MM-014763-001, Rev. G 7 1 REGULATORY AND SAFETY INFORMATION 1.1 SAFETY SYMBOL CONVENTIONS The following conventions are used in this manual to alert the user to general safety precautions that must be observed during all phases of operation, installation, service, and repair of this product. Failure to comply with these precautions or with specific warnings elsewhere violates safety standards of design, manufacture, and intended use of the product. Harris Corporation assumes no liability for the customer's failure to comply with these standards. The WARNING symbol calls attention to a procedure, practice, or the like, which, if not correctly performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING symbol until the conditions identified are fully understood or met. CAUTION The CAUTION symbol calls attention to an operating procedure, practice, or the like, which, if not performed correctly or adhered to, could result in damage to the equipment or severely degrade equipment performance. The NOTE symbol calls attention to supplemental information, which may improve system performance or clarify a process or procedure. 1.2 RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION FOR FCC OCCUPATIONAL USE REQUIREMENTS Before using the two-way mobile radio, review the following important RF energy awareness and control information and operational instructions. Comply with this information and instructions in order to ensure compliance with RF exposure guidelines. This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to remain below RF exposure limits. This radio is NOT authorized for general population, consumer, or any other use. CAUTION Changes or modifications not expressly approved by Harris could void the user's authority to operate the equipment. This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses RF energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. Experts in science, engineering, medicine, health, and industry work with organizations to develop standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
MM-014763-001, Rev. G 8 both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All two-way radios marketed in North America are designed, manufactured, and tested to ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of two-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Refer to the following websites for more information on what RF energy exposure is and how to control exposure to assure compliance with established RF exposure limits: http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov./SLTC/radiofrequencyradiation/index.html 1.2.1 Federal Communications Commission Regulations Before it was marketed in the United States, the M7300 two-way mobile radio was tested to ensure compliance with FCC RF energy exposure limits for two-way mobile radios. When two-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a label directing users to specific user awareness information. The radio has an RF exposure product label. Also, this Installation and Product Safety Manual and the applicable Operator’s Manual include information and operating instructions required to control RF exposure and to satisfy compliance requirements. 1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS The M7300 two-way mobile radio is designed and tested to comply with a number of national and international standards and guidelines regarding human exposure to RF electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not when it is receiving (listening), or in a standby mode. The M7300 two-way mobile radio complies with the following RF energy exposure standards and guidelines:  United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR § 2 sub-part J.  American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.  Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.  IC Standard RSS-102, Issue 2, 2005: Spectrum Management and Telecommunications Radio Standards Specification. Radiofrequency Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands). CAUTION Table 1-1 (for VHF radios) and Table 1-2 (for 700 and 800 MHz radios) list the recommended minimum safe lateral distances for a controlled environment and for unaware bystanders in an uncontrolled environment, from transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio power for mobile radios installed in a vehicle. Transmit only when unaware bystanders are at least the uncontrolled recommended minimum safe lateral distance away from the transmitting antenna.
MM-014763-001, Rev. G 9 Based on the highest radiated RF power and the highest antenna gain in antennas to be used with M7300, the distances listed in Table 1-1 (for VHF radios) and Table 1-2 (for 700 and 800 MHz radios) are considered as safe distances for controlled and uncontrolled environments with the M7300 mobile radio transmitting at a maximum 50% duty cycle: Table 1-1: Recommended Minimum Safe Lateral Distance from Transmitting Antenna Connected to a VHF M7300 Mobile Radio RECOMMENDED MINIMUM LATERAL HUMAN BODY DISTANCE FROM TRANSMITTING ANTENNA ANTENNA PART NUMBER ANTENNA DESCRIPTION CONTROLLED ENVIRONMENT (Centimeters) UNCONTROLLED ENVIRONMENT (Centimeters) AN102800V1 136 to 941 MHz, ¼-Wavelength*, Standard Rooftop-Mount; 0 dBd Gain 63 140 AN102800V2 136 to 941 MHz, ¼-Wavelength*, Thick Rooftop-Mount; 0 dBd Gain 63 140 AN-025147-001 (Discontinued) 136 to 174 MHz, Standard Rooftop-Mount; 0 dBd Gain 63 140 AN-025147-003 (Discontinued) 136 to 174 MHz, GPS Combo Rooftop-Mount; 0 dBd Gain 63 140 AN-025147-005 (Discontinued) 136 to 174 MHz, Magnetic-Mount; 0 dBd Gain 63 140 AN-125001-001 (mount) with AN-225002-001 (element) 136 to 174 MHz, Standard Rooftop-Mount; 0 dBd Gain 63 140 AN-125001-006 (mount) with AN-225002-001 (element) 136 to 174 MHz, GPS Combo Rooftop-Mount; 0 dBd Gain 63 140 AN-125001-007 (mount) with AN-225002-001 (element) 136 to 174 MHz, Magnetic-Mount; 0 dBd Gain 63 140 * Driven elements of AN102800V1 and AN102800V2 must be trimmed to proper lengths in order to minimize antenna system VSWR.

Use only approved/supplied antenna(s) or an approved replacement antenna. Unauthorized antennas, modifications, or attachments can cause the FCC RF exposure limits to be exceeded. 1.3.2 Approved Accessories The radio has been tested and meets FCC RF guidelines when used with accessories supplied or designated for use with it. Use of other accessories may not ensure compliance with the FCC’s RF exposure guidelines, and may violate FCC regulations. For a list of approved accessories refer to Section 4 in this manual (begins on page 24) and/or the Products and Services Catalog.
MM-014763-001, Rev. G 13 1.3.3 Contact Information For additional information on RF exposure and other information, contact Harris using one of the contact links listed in Section 3.4 on page 23. 1.4 OCCUPATIONAL SAFETY GUIDELINES AND SAFETY TRAINING INFORMATION To ensure bodily exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use. Always adhere to the following basic guidelines:  The push-to-talk button should only be depressed when intending to send a voice message.  The radio should only be used for necessary work-related communications.  The radio should only be used by authorized and trained personnel. It should never be operated by children.  Do not attempt any unauthorized modification to the radio. Changes or modifications to the radio may cause harmful interference and/or cause it to exceed FCC RF exposure limits. Only qualified personnel should service the radio.  Always use only authorized accessories (antennas, control heads, speakers/mics, etc.). Use of unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded. The information listed above provides the user with information needed to make him or her aware of a RF exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio. 1.5 COMMON HAZARDS The operator of any mobile radio should be aware of certain hazards common to the operation of vehicular radio transmissions. Possible hazards include but are not limited to:  Explosive Atmospheres — Just as it is dangerous to fuel a vehicle while its engine is running, be sure to turn the radio OFF while fueling the vehicle. If the radio is mounted in the trunk of the vehicle, DO NOT carry containers of fuel in the trunk. Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn the radio OFF when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the radio or its accessories could generate sparks.  Interference To Vehicular Electronic Systems — Electronic fuel injection systems, electronic anti-skid braking systems, electronic cruise control systems, etc., are typical of the types of electronic devices that can malfunction due to the lack of protection from radio frequency (RF) energy present when transmitting. If the vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits perform normally when the radio is transmitting.  Electric Blasting Caps — To prevent accidental detonation of electric blasting caps, DO NOT use two-way radios within 1000 feet (305 meters) of blasting operations. Always obey the “Turn Off Two-Way Radios” (or equivalent) signs posted where electric blasting caps are being used. (OSHA Standard: 1926.900).  Radio Frequency Energy — To prevent burns or related physical injury from radio frequency energy, do not operate the transmitter when anyone outside of the vehicle is within the minimum safe
MM-014763-001, Rev. G 14 distance from the antenna as specified in Table 1-1 (for VHF radios) and Table 1-2 (for 700 and 800 MHz radios). Refer to Section 1.2 for additional information.  Vehicles Powered By Liquefied Petroleum (LP) Gas — Radio installation in vehicles powered by liquefied petroleum gas, where the LP gas container is located in the trunk or other sealed-off space within the interior of the vehicle, must conform to the National Fire Protection Association standard NFPA 58. This requires:  The space containing the radio equipment must be isolated by a seal from the space containing the LP gas container and its fittings.  Outside filling connections must be used for the LP gas container.  The LP gas container space shall be vented to the outside of the vehicle.  Vehicles Equipped with Airbags — For driver and passenger safety, avoid mounting the radio’s control head (or any other component) above or near airbag deployment areas. In addition to driver-side and passenger-side front-impact airbags, some vehicles may also be equipped with side-impact airbags. For occupant safety, verify the location of all airbags within the vehicle before installing the radio equipment. 1.6 SAFE DRIVING RECOMMENDATIONS The American Automobile Association (AAA) advocates the following key safe driving recommenda-tions:  Read the literature on the safe operation of the radio.  Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in motion.  Place calls only when the vehicle is stopped.  When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations brief.  If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and continue the call.  Whenever using a mobile radio, exercise caution. 1.7 OPERATING RULES AND REGULATIONS Two-way radio systems must be operated in accordance with the rules and regulations of the local, regional, or national government. In the United States, the M7300 mobile radio must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). Operators of two-way radio equipment, must be thoroughly familiar with the rules that apply to the particular type of radio operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing radio channels, and results in a smoothly functioning radio network. When using a two-way radio, remember these rules:  It is a violation of FCC rules to interrupt any distress or emergency message. The radio operates in much the same way as a telephone “party line.” Therefore, always listen to make sure the channel is clear before transmitting. Emergency calls have priority over all other messages. If someone is sending an emergency message – such as reporting a fire or asking for help in an accident, do not transmit unless assistance can be offered.
MM-014763-001, Rev. G 15  The use of profane or obscene language is prohibited by Federal law.  It is against the law to send false call letters or false distress or emergency messages. The FCC requires keeping conversations brief and confined to business. Use coded messages whenever possible to save time.  Using the radio to send personal messages (except in an emergency) is a violation of FCC rules. Send only essential messages.  It is against Federal law to repeat or otherwise make known anything overheard on the radio. Conversations between others sharing the channel must be regarded as confidential.  The FCC requires self-identification at certain specific times by means of call letters. Refer to the rules that apply to the particular type of operation for the proper procedure.  No changes or adjustments shall be made to the equipment except by an authorized or certified electronics technician. CAUTION Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of the United States may be punishable by a fine of up to $10,000, imprisonment for up to two (2) years, or both. 1.8 OPERATING TIPS The following conditions tend to reduce the effective range of two-way radios and should be avoided whenever possible:  Operating the radio in areas of low terrain, or while under power lines or bridges.  Obstructions such as mountains and buildings. In areas where transmission or reception is poor, communication improvement may sometimes be obtained by moving a few yards in another direction, or moving to a higher elevation.

MM-014763-001, Rev. G 19 3 INTRODUCTION This manual contains installation procedures for the M7300 mobile radio, the CH-721 control heads, and the HHC-731 hand-held controller. Procedures cover the mounting and cabling of the equipment, as well as the basic in-vehicle test procedures. In addition, product safety-related information is included. 3.1 GENERAL DESCRIPTION The M7300 mobile radio is a high-performance digital mobile radio. Shown in Figure 5-3 on page 37, the M7300 mobile radio is available in both a VHF-band-only radio and a dual-band 700 and 800 MHz radio. 3.1.1 VHF-Band M7300 Radio The VHF-band M7300 radio can operate in the 136 to 174 MHz RF band with the following radio systems/standards:  APCO Project 25 Phase I compliant Common Air Interface (P25 CAI) trunked radio networks;  Talk-around communications in accordance with the APCO Project 25 Phase I standard; and,  Conventional FM repeater-based and FM talk-around voice communications in VHF-band in accordance with the TIA/EIA-603 conventional land-mobile radio standard. 3.1.2 Dual-Band 700 and 800 MHz M7300 Radio The dual-band 700 and 800 MHz M7300 mobile radio can operate with the following radio systems/-standards:  700 MHz and 800 MHz OpenSky® trunked radio networks using the OpenSky Trunking Protocol (OTP);  800 MHz Enhanced Digital Access Communications System (EDACS®) trunked radio networks;  800 MHz ProVoice™ trunked radio networks;  800 MHz APCO Project 25 Phase I compliant Common Air Interface (P25 CAI) trunked radio networks;  700 MHz talk-around communications in accordance with the APCO Project 25 Phase I standard; and,  Conventional FM repeater-based and FM talk-around voice communications in 700 and 800 MHz bands in accordance with the TIA/EIA-603 conventional land-mobile radio standard. 700 MHz operating bands of the dual-band M7300 mobile radio include the repeater output bands (mobile receive) of 764 to 767 MHz, 769 to 775 MHz and 773 to 776 MHz, and the repeater input bands (mobile transmit) of 794 to 797 MHz, 799 to 805 MHz and 803 to 806 MHz. The radio also provides talk-around operation in the 764 to 767 MHz, 769 to 775 MHz and 773 to 776 MHz bands. In high-power transmit mode on a 700 MHz RF channel, the radio’s rated transmit output power is 19 watts. 800 MHz operating bands of the dual-band M7300 mobile radio include 806 to 824 MHz repeater input band (mobile transmit) and the 851 to 869 MHz band used for repeater output and talk-around communications. In high-power transmit mode on an 800 MHz RF channel, the radio’s rated transmit output power is 35 watts. 3.1.3 General Information The M7300 is designed to operate in a mobile environment, typically within a motor vehicle. It must be connected to an external transmit/receive antenna such as one mounted to the vehicle’s rooftop or trunk
MM-014763-001, Rev. G 20 lid. Several different types of external-mount antennas are approved and available for use with the radio, as listed in Table 1-1 (for VHF radios) and Table 1-2 (for 700 and 800 MHz radios), and in Table 4-7. Front-mount and remote-mount M7300 radio configurations are available. In the front-mount configuration, the control head is an integral part of the mobile radio. In the remote-mount configuration, the control head is located near the radio operator’s position and the radio is mounted remotely from the control head, typically in the vehicle’s trunk. As described later in this section, a HHC-731 hand-held controller can be connected to a remote-mount radio, in place of the CH-721 control head. The remote-mount radio is shown in Figure 5-3 on page 37. Control heads used with the M7300 radio include the CH-721 Scan and the CH-721 System model control heads. See Figure 8-5 (page 67) through Figure 8-7 (page 68). Both heads feature a large 3-line graphical vacuum-fluorescent display, front panel controls and buttons/keys for user control of the mobile radio, an internal high-power audio amplifier to drive an externally-connected speaker, and a front panel microphone connector. The CH-721 System control head also has a 12-button numeric keypad that provides Dual-Tone Multi-Frequency (DTMF) functionality and easier operator system/group selection control at the control head’s front panel. In a remote-mount M7300 mobile radio installation, the HHC-731 hand-held controller can be used in place of the CH-721 control head. This easy-to-use hand-held mobile radio controller is primarily designed for use in harsh environments such as maritime (i.e., boating) applications and All-Terrain Vehicle (ATV) applications. The HHC-731 hand-held controller has easy-to-use buttons, a tough liquid-crystal display (LCD), and a built-in microphone. As of the publication of this manual, only one (1) HHC-731 hand-held controller can be connected to a radio, and without any connected CH-721 control heads. The front of the HHC-731 hand-held controller is shown in Figure 8-14 on page 77. The remote-mount M7300 radio is designed for remote mounting in a motor vehicle’s trunk, or some other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf. Up to four (4) control heads can be connected to a front-mount M7300, and up to five (5) control heads can be connected to a remote-mount M7300. The radio is remotely controlled by a control head(s) connected to it via 3-wire Controller Area Network (CAN) cables. Between the radio and control head(s), the CAN link carries digitized microphone and speaker audio, controlling data such as button presses and radio messages, and user data such as that for a mobile data terminal connected to the serial port of the radio or control head. For proper operation, the CAN link must be terminated appropriately on each end. In multiple control head installations, two or more control heads are interconnected to the mobile radio in a series (“daisy-chain”) fashion via CAN link cables. As shown in Figure 8-7 on page 68, the CH-721 Scan and System model control heads used in remote-mount radio installations have several connectors located on the head’s rear panel. These connectors include a DC power connector, two (2) CAN port connectors used for CAN link interconnections, an external speaker connector, a 9-pin serial port connector for connecting optional equipment such as a mobile data terminal, and a 25-pin accessory connector. Both CH-721 models can interface to an optional Federal Signal Electronic siren/light control system for broadcasting via a public address (PA) speaker. The radio and control head/hand-held controller must be powered by an external +13.6-volt (nominal) DC power source. In mobile applications, the motor vehicle’s electrical system is utilized as the source of DC power. In a remote-mount radio installation, the CH-721 control head(s) or the HHC-731 hand-held controller connected to the radio is also powered by the same DC power source, but separately fused. When the control head/hand-held controller is powered-up by the operator, it “wakes up” the radio by transmitting data to the radio via the CAN link. The radio provides half-duplex voice and data communications. Voice communications are accomplished via a “push-to-talk” (PTT) type microphone and an external speaker connected to the control head. The HHC-731 hand-held controller has an integrated microphone and PTT button/key. When a control head is
MM-014763-001, Rev. G 21 employed in a mobile radio installation, an audio amplifier in the head drives the speaker. When the hand-held controller is employed, an audio amplifier in the remote-mounted mobile radio drives the speaker. For data communications, the radio has an industry-standard 9-pin serial interface port for connecting optional data-type equipment, such as a Mobile Data Terminal (MDT), a laptop PC, an external display, or a key-entry device. This port works seamlessly with equipment from popular manufacturers and off-the-shelf applications. OpenSky employs User Datagram Protocol over Internet Protocol (UDP/IP) data packet transfers, providing “plug and play” connectivity for data-type devices. The radio has an optional built-in Global Positioning System (GPS) tracking receiver. On an OpenSky trunked radio network, the GPS tracking receiver can provide quick and accurate unit location information to dispatchers via the radio network. The GPS receiver determines the unit’s location and the radio transmits it to the network, either when polled by the network or automatically on a predetermined periodic basis. The GPS antenna can be integrated into the mobile transmit/receive antenna (i.e., a “combination” antenna). Alternately, the GPS antenna can be located/mounted completely separate from the mobile transmit/receive antenna. The M7300 mobile radio, the CH-721 control head and the HHC-731 hand-held controller exceed tough environmental specifications included within military standard MIL-STD-810F, the radio industry standard TIA/EIA-603, and the radio standard established by the U.S. Forest Service. An M7300 radio operating on an OpenSky radio network uses Time-Division Multiple-Access (TDMA) digital modulation technology on the radio frequency link. TDMA allows multiple radio users to share a single RF channel. In addition, a single RF channel can support simultaneous digital voice and data communications. OpenSky employs Advanced Multi-Band Excitation (AMBE®) speech and data compression technology developed by Digital Voice Systems, Inc. When operating on an OpenSky radio network, AMBE gives an M7300 the ability to provide exceptional voice quality via the limited bandwidth of the radio frequency path, even when the received RF signal is weak (i.e., even in “fringe” areas). AMBE is performed by a Digital Signal Processor (DSP) integrated circuit within the radio programmed to perform an AMBE compression algorithm during mobile transmissions, and an AMBE expansion algorithm during mobile reception. Speech compression electronic circuitry—be it AMBE or another type such as IMBE®—is sometimes referred to as “vocoding” circuitry for voice coding, or simply a “vocoder” circuit. The M7300 mobile radio supports operation on APCO Project 25 phase I compliant Common Air Interface (P25 CAI) trunked radio networks, and operation in a talk-around mode in accordance with the APCO Project 25 phase I standard. P25 radio systems utilize Improved Multi-Band Excitation (IMBE) speech and data compression technology, also developed by Digital Voice Systems, Inc. Like AMBE technology, IMBE technology allows the M7300 to deliver exceptional voice quality, even in areas where the received RF signal strength is weak. IMBE replicates human speech better than other voice compression technologies, resulting in better voice quality and better speaker recognition. The Telecommunications Industry Association (TIA) funded an independent study to evaluate compression technologies. The findings showed that when compared with other industry-recognized compression technologies, IMBE provided the highest voice quality. In the study, radio users were asked to listen to coded speech produced by four different compression technologies (i.e., vocoder circuits) operating under a variety of conditions. The users rated the speech on a scale of one to five, with five being the best quality. Under each operating conditions, IMBE was rated the best. The M7300 mobile radio can also operate using Harris’ digital voice technology called ProVoice. Like P25 radio systems, ProVoice also employs IMBE technology.
MM-014763-001, Rev. G 22 EDACS and ProVoice trunked radio networks employ analog FM and 2-level Gaussian Frequency-Shift Keying (GFSK) modulation techniques on the RF channels. Data is transmitted on an RF channel at a 9600 bits-per-second rate. For over-the-air secure radio communications, the M7300 mobile radio may be equipped for 64-bit DES (Data Encryption Standard) encryption or 128/256-bit AES (Advanced Encryption Standard) encryption. With encryption, voice and/or user data signals transmitted and received by the radio on an RF channel are digitally encrypted (“scrambled”) to virtually eliminate unauthorized monitoring via the RF channel.

MM-014763-001, Rev. G 38 5.3 LOCATING COMPONENTS Plan the mounting locations of all components (radio, control head/hand-held controller, antenna, and cables) and determine the routes for all wiring and cables. Particularly consider the connection of the radio for planning purposes.  Determine the customer’s preferences, if any, for location of components. Comply with these preferences as long as they are consistent with safety recommendations and guidelines presented in this manual, and other generally accepted professional radio installation practices.  For a front-mount installation, the radio is typically located under the vehicle’s dash panel. However, it may be mounted above the dash, or at some other location per customer requirements, available space, and/or mounting surface strength. Dimensions for the radio, control head, and hand-held controller are listed in Section 2.1 on page 16. As noted in that section, these dimensions do not include space required at the rear of the radio for cables. Several inches of clearance space is required.  For a remote-mount radio installation, the radio is typically located in the motor vehicle’s trunk, or some other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf. The control head is typically located under the vehicle’s dash panel. Dimensions for the radio, control head, and hand-held controller are listed in Section 2.1 on page 16. As noted in that section, these dimensions do not include space required at the rear of the radio and control head for cables. Several inches of clearance space is required at the back of the control head, and at least six (6) inches is recommended at the back of the radio. In addition, several inches of clearance space is required at each side of the radio for access to the screws that secure the radio to its mounting bracket.  When selecting a mounting location, verify sufficient clearance behind the radio can be maintained so cables will not be stressed, crushed, twisted, or bent at severe angles. This also applies to the control head in a remote-mount radio installation. Also, the front and sides of the units must have clearance for air circulation, access to mounting screws, mounting hardware, etc.  Verify the drilling of holes and the insertion of screws will not damage or interfere with any existing vehicle components (for example, a fuel tank, fuel lines, the transmission housing, etc.), or any existing vehicle wiring.  For antenna location and installation-related information, refer to Section 6. CAUTION The radio must be kept out of direct sunlight and away from heat sources. Adequate free-air ventilation must be provided to its rear fins. The radio will automatically reduce its transmit RF output power when its ambient temperature exceeds approximately +140° Fahrenheit (+60° Celsius). CAUTION All cables should have a service loop near each connector end. Do not bend the cables at severe angles near the connector end. Above all, after all components are installed, verify no cable is under any tension. Failure to do so may lead to damaged cables, causing intermittent radio operation or complete radio failure.
MM-014763-001, Rev. G 39 6 ANTENNA INSTALLATION 6.1 ANTENNA MOUNTING LOCATIONS At this time, review all information presented in the REGULATORY AND SAFETY INFORMATION section of this manual (see page 7). A transmitting antenna must be installed in accordance with the guidelines presented in both the REGULATORY AND SAFETY INFORMATION section, and in this section. As a guide for determining the best possible mounting location in order to reduce human exposure to radio frequency (RF) electromagnetic energy during transmit mode, use Table 1-1 for a VHF radio, Table 1-2 for a 700 and 800 MHz radio, and Figure 6-1. Antennas must be mounted in one of four (4) possible locations on the vehicle. Figure 6-1 shows the recommended locations and antenna part numbers. Also, see Table 4-7 for additional information. Always follow the antenna manufacturer’s instructions when mounting an antenna. 6.1.1 Direct Center or Center-Rear of Rooftop The center of the vehicle’s roof is the best location for a rooftop-mount antenna (location  in Figure 6-1). For optimal performance, the mounting area under the antenna must be a flat with a minimum radius of six (6) inches of metal ground plane. It must be located directly in the center of the roof to minimize human exposure to RF electromagnetic energy. Other obstructions such as a light bar or another antenna may prevent the antenna from being mounted in the direct center of the roof. In this case, the antenna should be mounted a minimum of one foot away from and behind the obstruction but in the middle of the roof with respect to the left and right sides of the vehicle (location  in Figure 6-1). 6.1.2 Center of Trunk Lid Certain vehicles do not allow for the antenna to be placed in the center or center-rear of the roof. In this case, the next best location for the antenna is in the direct center of the trunk lid (location  in Figure 6-1). In this case, an elevated-feed-point antenna is recommended. Although this type of antenna does not require a metal ground plane, it must be located directly in the center of the trunk lid to minimize human exposure to RF electromagnetic energy. 6.1.3 Rear Deck Lid for Stand-Alone GPS Receive Antenna If the M7300 mobile radio does not use a GPS combination-type antenna and it is equipped with a GPS receiver, a stand-alone GPS receive antenna must be separately located and mounted. The vehicle’s rear deck lid (location  in Figure 6-1) is the recommended mounting location for this case. This locates the GPS antenna inside the vehicle.

MM-014763-001, Rev. G 42 6.2 ANTENNA INSTALLATION PROCEDURES An antenna must be installed before completing the radio installation. Table 4-7 (page 31) and Figure 6-1 (page 41) list the mobile radio antennas available for use with the radio. As presented in the previous section, various mounting locations exist. Optimal performance is achieved via a rooftop antenna mounted in the direct center of the motor vehicle’s roof. 6.2.1 Installing NMO Antenna Mounts AN-125001-001, -002, -003 and -004 These NMO style antenna mounts can each be used with several different antenna elements. Only limited access under the mounting location is typically required. The installation procedure is presented in Section 6.2.1.3. 6.2.1.1 Standard NMO Antenna Mounts AN-125001-001 and AN-125001-002 These standard ¾-inch NMO antenna mounts require a ¾-inch hole in a relatively flat area of the vehicle body, with a vehicle metal thickness of between 0.020 and 0.040 inches. AN-125001-002 has a very-low-loss coax cable (LMR-195 or equivalent). 6.2.1.2 Thick-Roof NMO Antenna Mounts AN-125001-003 and AN-125001-004 Both of these thick-roof NMO antenna mounts use either a ⅜-inch or a ¾-inch mounting hole in a relatively flat area of the vehicle body, with a vehicle metal thickness of between 0.040 and 0.1875 inches (3/16-inch maximum thickness). AN-125001-004 has a very-low-loss coax cable (LMR-195 or equivalent). For thick-roof NMO antenna mounts AN-125001-003 or AN-125001-004, using a ⅜-inch mounting hole will require better access to the underside of the mounting location than if a ¾-inch hole is used. This is because, in the case of a ⅜-inch hole, the antenna mount’s bushing assembly must be inserted from the underside of the mounting surface. When using a ¾-inch mounting hole to mount thick-roof NMO antenna mounts AN-125001-003 or AN-125001-004, the thickness of the mounting surface must be at least ⅛-inch (0.125-inch minimum thickness). This requirement is due to the thickness of the alignment ring used to center the bushing assembly within the ¾-inch mounting hole. 6.2.1.3 Installation Procedure for Mounts AN-125001-001 through -004 1. Select the antenna mounting location in accordance with the information presented in Sections 1 and 6.1 of this manual. If necessary, contact the Technical Assistance Center for assistance. See page 23 for TAC contact information. 2. Verify no obstructions exist immediately below the respective mounting location on the underside of the vehicle body, such as vehicle ribbing/body framing, a wiring harness, air bag equipment, etc. Also verify there is a sufficient access path and clearance for the mount’s coax cable. If there is an obstruction or insufficient clearance, select another nearby mounting location. 3. Measure and mark the center point of the selected antenna mounting location. Be sure to center the mark from side-to-side of the vehicle.
MM-014763-001, Rev. G 43 4. Obtain a hole saw specifically designed for drilling NMO mounting holes of the required diameter. (e.g., Antenex/Laird Technologies model HS34 or equivalent for a ¾-inch hole; Antenex/Laird Technologies model HS38 or equivalent for a ⅜-inch hole). 5. If the vehicle’s headliner panel, carpet, seats, or otherwise, is below the mounting location, move or remove the headliner panel, etc. as necessary to protect it. Alternately, apply a heat-resistant mask material (such as a fiberglass mat or thin sheet metal with masked edges) as required to “catch” the metal shavings and the metal plug (if any) produced by the hole saw. The plug (if any) may be relatively hot if/when it drops out of the saw upon completion of the hole drilling process. ⅜-inch diameter hole saws generally produce only shavings, not plugs. 6. With the hole saw and a drill, drill a hole at the marked hole center point. Position the drill square to (i.e., 90 degrees from) the vehicle mounting surface so paint immediately outside of the perimeter of the hole is evenly removed. CAUTION Excessive use of the hole saw and/or failure to position the drill “square” with (i.e., at a 90-degree angle from) the vehicle mounting surface may result in damage to the metal mounting surface, in the area immediately outside of the perimeter of the hole. 7. Ensure the saw removed the paint immediately around the hole as the drilling operation completed. If not, do so by reinserting the saw completely into the hole and spinning it as required. This allows proper grounding via the mount’s lock nut on the top of the mounting surface. On the bottom of the mounting surface, the “teeth” of the mount’s bushing assembly may not provide a good ground due to thick vehicle undercoating, thick primer, oxidation/rust, etc. 8. For a ¾-inch hole, feed the unterminated end of the mount’s coax cable into the hole from the top surface of the vehicle until the mount’s bushing assembly is in position to drop into the hole. The bushing should be tilted at a slight angle and fed into the hole. The threaded shank of the mount’s bushing assembly will not fall through a ¾-inch hole. For a ⅜-inch hole, feed the threaded shank of the mount’s bushing assembly into the hole from the underside of the mounting surface. Hold it into position until the lock nut is installed. 9. If installing a thick-roof antenna mount (⅜-inch shank) into a ¾-inch hole, place the alignment ring onto the threaded shank of the mount. This ring has an approximate ¾-inch outside diameter. 10. A tube of synthetic lubricant is included with the antenna mount. Apply this lubricant to the mount’s rubber O-ring. Do not get any lubricant on the center contact of the mount’s bushing assembly. 11. As illustrated in Figure 6-2 and Figure 6-3, add the O-ring (C) and lock nut (D) to the top of the mount’s bushing assembly (A). With the O-ring in the groove in the underside of the lock nut, thread the lock nut onto the bushing assembly. Be sure the O-ring remains in the groove before tightening the lock nut. 12. Using a 15/16-inch open-end wrench, tighten the lock nut until it fully compresses the O-ring and makes good contact with the vehicle mounting surface. The groove’s ridges on the bottom of the lock nut must make full contact with the unpainted metal surface of the vehicle. 13. Install the antenna element per the procedure in Section 6.2.4.

Thoroughly clean the bottom of the magnetic mount and the selected vehicle mounting surface by removing all dust, dirt, etc. 2. Carefully place the magnet mount onto the metal surface of the vehicle at the selected location. The coax cable exiting the mount’s base should be orientated towards the point at which it will enter into the interior of the vehicle. Do not try to reposition it by sliding it on a painted metal surface. 3. Route the mount’s coax cable to the radio location, passing it by trunk lid’s perimeter gasket, door perimeter gasket, etc., as necessary. 4. Install the antenna element per the procedure in Section 6.2.4.

MM-014763-001, Rev. G 45 CAUTION To remove a magnetic antenna mount, hold it at the bottom of its base and tilt it at an angle to release the magnetic attraction force. Do not pull on the mount’s coax cable. Do not drag the mount across the mounting surface. 6.2.3 Installing All Other Antenna Mounts For any other type of antenna mount not covered in the previous sections, such as GPS combination antennas, install the mount in accordance with the installation instructions included with the mount. 6.2.4 Attaching NMO Antenna Elements 1. Clean the top surface of the NMO mount and the surface of the vehicle immediately around the mount. 2. Place the gasket included with the antenna element (not pictured in Figure 6-2 or Figure 6-3) around the mount and against the surface of the vehicle. If a lubricate or sealant was included with the gasket, apply it to the gasket before placing the gasket. 3. Apply the antenna element to the top of the mount and tighten it in a clock-wise direction (as viewing from the top). Use an appropriate wrench if required. Do not over-tighten. 4. Install a placard (not supplied) on the vehicle’s dash panel, in accordance with the following CAUTION. Place the placard in plain view of the vehicle operator’s position. CAUTION Before entering any automatic vehicle (“car”) wash equipment, remove the antenna element from the antenna mount, and secure the element in a safe location inside the vehicle. This will prevent the wash equipment from damaging the element and/or mount. After exiting the wash equipment, thoroughly dry the top of the mount before re-installing the element. 5. Continue with the connection procedure presented in the next section. 6.2.5 Installing the Coax Cable and TNC RF Connector 1. Route the coax cable from the antenna mount to the location where the mobile radio will be installed. Remove headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual contact from persons within the vehicle. Tie and stow the cable as necessary to protect it from possible chafing. The antenna cable should never be cut to a shorter length. Instead, excess cable must be tied and stowed. This not only prevents the antenna from radiating above its intended or configured power, but it also allows for future re-installation considerations such as a relocation of the mobile radio within the vehicle. Installations requiring longer cables are treated as custom and separately specified. 2. Using an appropriate crimp tool, crimp the supplied TNC RF connector to the end of the antenna cable. For crimping instructions, see Figure 6-4 or the instructions supplied with antenna mount. 3. The antenna cable is connected to the radio’s TNC receptacle-type (female) RF connector per a procedure presented later in this manual. The cable and its TNC connector must be protected from damage, dirt, and/or metal shavings which may be generated during the mechanical and electrical installation of the radio. Temporarily tying the connector and cable-end within a small plastic bag is recommended.

A) Figure 6-4: Crimping Instructions for TNC RF Connector 6.2.6 Install GPS Antenna (Required Only if Radio has GPS Receiver Option) If the M7300 radio is equipped with the GPS receiver option, the GPS receiver requires connection to an externally-mounted GPS antenna. The GPS antenna must be kept at least six (6) inches away from any other antenna mounted on the vehicle and it must have at least six inches of surface ground plane beneath it. The following antenna installation procedure is recommended: A combination (“combo”) antenna kit includes a GPS antenna built into the base of the mobile antenna. Refer to Table 4-7 (page 31) and/or Figure 6-1 (page 41) for available combo antennas. 1. After selecting a mounting location, refer to the antenna manufacturer’s mounting and testing instructions for installation guidance. Install the antenna in accordance with these instructions. If necessary, contact the Technical Assistance Center. See page 23 for TAC contact information. Do not alter the GPS antenna cable length; tie and stow excess cable as necessary. 2. Route the cable from the antenna base to the location of where the radio will be installed. Remove headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual contact from persons within the vehicle. Tie and stow it as necessary to protect it from possible chafing. 3. The antenna cable is connected to the radio’s SMA receptacle-type (female) RF connector per a procedure presented later in this manual. The cable and its (male) SMA connector must be protected from damage, dirt, and/or metal shavings which may be generated during the mechanical and electrical installation of the radio. Temporarily tying the connector and cable-end within a small plastic bag is recommended.
MM-014763-001, Rev. G 47 7 FRONT-MOUNT RADIO INSTALLATION This section includes detailed instructions for mechanically installing and wiring a front-mount M7300 mobile radio. For remote-mount M7300 mobile radio installation procedures, refer to Section 8 which begins on page 57. 7.1 MOUNTING THE FRONT-MOUNT RADIO The Mounting Bracket Kit for the front-mount M7300 mobile radio includes a heavy-gauge steel U-shaped mounting bracket. The radio should be attached to a mounting surface using this bracket. The bracket can be mounted above or below the radio. Kit contents are shown in Figure 7-2, and bracket dimensions are shown in Figure 7-3. Both the radio and the mounting bracket have multiple holes in both sides for adjusting the radio within the bracket. The design allows for both front-to-rear tilting of the radio within the bracket for best viewing angle, and a front-to-rear position offset. The radio has six (6) threaded mounting holes, three (3) per side, and the mounting bracket has ten (10) corresponding holes, five (5) per side. The radio must be secured to the bracket using at least four of the six M5 socket-head screws included in the Mounting Bracket Kit (2 screws per side). Typically, the radio is front-to-rear centered within the bracket. However, it can be front-to-rear offset by approximately 2 inches (5.1 centimeters), if required. Also, the radio can be positioned straight in the bracket (i.e., parallel with the bottom surface of the bracket), or it can be tilted up or down at an angle of between approximately 10 to 20 degrees. When positioned straight and centered front-to-rear within the bracket, the radio extends approximately 2.5 inches (6.4 centimeters) from the front and rear edges of the bracket. In the rear, additional clearance must be included for cables. The area directly at the front of the radio must be completely clear of all objects (e.g., gear shift, other radio equipment, etc.) so the operator can easily access and visualize the radio’s control head. The mounting bracket must be attached to a secure metal surface that meets or exceeds the minimum 1/16-inch-thick steel sheet metal requirement in accordance with the following WARNING. For example, it can be attached directly to the bottom of the dash if the gauge of the sheet metal is high and the surface is firm and flat, or it can be attached to the transmission hump, etc., if a mounting wedge (not included) is utilized. The front-mount M7300 radio weighs approximately 9.2 pounds (4.17 kilograms). At a minimum, the mounting surface should be 16-gauge (approximately 1/16-inch thick) steel sheet metal. Mounting to plastic or other material with low tensile and shear strength could lead to an unsafe and/or failed mounting condition, turning the radio and its mounting bracket into a projectile during a high-shock incident such as a motor vehicle accident. If the selected mounting surface does not meet the minimum 16-gauge steel sheet metal requirement, the surface should be reinforced with a metal backing plate (not supplied) or it should be reinforced using some other approved mounting method. CAUTION In addition to improving safety of the installation, firm mounting also prevents unreasonable vibration that could damage the radio, adversely affect transceiver performance and/or cause its cable connections to loosen. An improperly mounted M7300 radio may experience degradation in the quality of voice and data communications.

MM-014763-001, Rev. G 49 7.1.1 Mounting Bracket Installation The front-mount M7300 radio’s mounting bracket is included with the Front-Mount Mounting Bracket Kit KT101533V1. Kit contents are shown in Figure 7-2. This kit is Item 1 listed in Table 4-4 (page 26). Mounting Bracket Self-Tapping Screws for FM101319V1 Securing Bracket (Marked KTB0310), M5 Hardware for to Mounting Surface Ties and Grommet Securing Radio to Bracket Figure 7-2: Front-Mount Mounting Bracket Kit KT101533V1 When selecting a mounting location for the radio, verify sufficient clearance can be maintained around the radio for installation and service access. A minimum clearance of approximately four (4) inches (10 centimeters) is recommended at the rear, left and right sides of the radio. As previously stated, the area directly at the front of the radio must be completely clear of objects so the operator can easily access and visualize the radio’s control head. As illustrated in Figure 7-3, the bracket is both left-to-right and front-to-rear symmetrical. It has eleven (11) holes for securing it to a mounting surface. At least four (4) of these holes must be used to secure the bracket to the mounting surface. Five 20-millimeter-long self-tapping screws are included in the Mounting Bracket Kit for this purpose. However, some other type of hardware (not supplied) may be used, such as #10-32 stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts), or self-drilling screws. Self-drilling screws such as “TEK” screws do not require drilling of a pilot hole prior to installation. Do not use common self-threading sheet metal screws because they will loosen over time with vehicle vibrations. The following mounting procedure is recommended: 1. Determine the best radio-to-bracket position and angle by test-fitting the radio into the mounting bracket at the selected vehicle mounting location. Slide the radio between the sides of the bracket and temporarily secure it to the bracket with several of the M5 socket-head screws from the bracket kit. When positioned straight and centered front-to-rear within the bracket, the radio extends approximately 2.5 inches (6.4 centimeters) from the front and rear edges of the bracket. In the rear, additional clearance must be included for cables. The area directly at the front of the radio must be completely clear of all objects (e.g., gear shift, other radio equipment, etc.) so the operator can easily access and visualize the radio’s control head. 2. At the rear of the radio, verify sufficient clearance is available for cables and service access.

If the mounting surface is not flat (such as the top of a transmission hump), construct a suitable mounting wedge as necessary, and attach the wedge to the surface using an approved attachment method. Never mount the bracket directly to a non-flat surface. 4. On the mounting surface, mark the selected location for the bracket, and then remove the radio from the bracket. 5. Clean and remove any foreign material from the mounting surface. Bracket-To-Vehicle Screw Holes (11 places)Bracket-To-Radio Screw Holes(10 places, 5 each side)
MM-014763-001, Rev. G 51 6. Using the bracket as a template, and/or the dimensional information shown in Figure 8-3, mark and drill at least four (4) mounting holes into the mounting surface as required per the type of hardware used. CAUTION Before drilling holes and/or installing mounting screws, verify these operations will not damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the transmission housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. Always deburr drilled holes before installing screws. 7. Temporarily remove the bracket and deburr all of the newly drilled holes. 8. If necessary, apply an approved paint or rust-inhibitor at the holes in the mounting surface. 9. Set the bracket back into place. 10. Install and tighten the mounting screws/hardware. 11. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable vibration, which could damage the radio and/or cause its cable connections to loosen. 12. If the rear of the radio is easily accessible when the radio is positioned in the selected position within the bracket, it is recommended that the radio be temporarily inserted into the bracket. Otherwise, do not mount the radio into the bracket at this time, because several cable connections must be made at the rear of the radio. 7.1.2 Inserting the Radio into the Mounting Bracket The radio should now be inserted into the mounting bracket according to this procedure: 1. Lay the radio into the mounting bracket with the front of the radio facing in the correct direction (usually towards the rear of the vehicle). 2. Secure the radio to the bracket using at least four (4) of the six (6) M5 x 10 mm stainless-steel socket-head screws included with the Mounting Bracket Kit. These screws have captive lockwashers. Kit contents are shown in Figure 7-2. This kit is Item 1 listed in Table 4-4 (page 26). 3. Tighten all screws using a 4-millimeter hex key wrench until each lockwasher is fully compressed and the radio is firm and flush in between the brackets. 4. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an area to secure and rest the excess cable lengths. Proper mounting is one factor that ensures optimal radio performance. An improperly mounted radio may experience degradation in the quality of voice and data communications. 7.2 FRONT-MOUNT RADIO’S DC POWER INSTALLATION 7.2.1 Overview of On/Off Power Wiring Configurations The following power wiring configurations are supported:  Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the
MM-014763-001, Rev. G 52 radio. The white wire of the radio’s DC Power Cable is connected to a fused switched power source, typically identified as vehicle “Accessory” power. This source must switch on (up to positive (+) battery voltage potential) when the vehicle’s ignition switch/key turns on, and it must switch off (to near zero volts) when the ignition switch/key turns off. The required fuse rating is 3 amperes. When using this configuration, the on/off/volume control must be left in the on position for automatic power-up/down to function properly. In a front-mount M7300 radio installation, to fuse the white wire of the radio’s DC Power Cable, a yellow waterproof (HFB type) fuse holder and a 3-amp AGC fuse are included with the cable.  Radio turns on and off with a manual switch — This configuration is used when, for example, the radio has to remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable. The white wire of the radio’s DC Power Cable is connected to one side of a manually-controlled switch, and the other side of this switch is connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes. When using this configuration, the on/off/volume control must be left in the on position for automatic power-up/down to function properly.  Radio turns on with its on/off/volume control (“hot wired”) — This configuration allows radio on/off power control only via its on/off/volume control. It may be desired if, for example, the radio has to remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is not desired and/or not acceptable. The white wire of the radio’s DC Power Cable must be connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes. In all of the above cases, the radio’s main DC power input (red wire) must be connected through an in-line fuse to unswitched vehicle DC power. The red wire must be connected to raw battery power (positive battery terminal) via the supplied fuse. CAUTION Any DC input power provided to the radio shall be no higher or lower than 13.6 volts DC 10%. The DC input power should be free and clear of any AC noise or DC spikes above 18 volts. If the vehicle cannot meet these requirements, then DC conditioning will be required before any DC power is connected to the radio. This includes conditioning for both the radio’s main DC power input lead and for its switched ignition sense power input. DC conditioning can be accomplished by a noise filter or DC isolation equipment such as Harris part number FL-018314-001 or FL-018314-002, or similar units with equal specifications. The fuse must be placed in-line before any noise filter. Contact TAC for additional information. 7.2.2 DC Power Cable and Main Fuse Holder Installation The radio’s DC Power Cable has a 3-pin connector, a 20-foot red wire (for the main power connection), a 20-foot white wire (for the switched power source connection), and a 4-foot black wire (for the ground connection). It is supplied with waterproof fuse holders, two AGC-type fuses, and non-insulated ring terminals. The following installation procedures are recommended: 7.2.2.1 Black Wire Connection (Ground Wire) 1. Connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s 3-pin power cable connector as follows: Visually align the key and firmly push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm proper mating.
MM-014763-001, Rev. G 53 2. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal within approximately two (2) feet of the radio. This surface must have a solid and stable connection to vehicle ground. If not, add grounding strap(s) as necessary. 3. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square. 4. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-insulated ring terminal is supplied with the cable to make this ground connection. Therefore, hole diameter should be appropriate for the utilized grounding screw/bolt size and type used to connect the ring terminal to the bare metal surface. This hardware is not supplied. 5. Cut the black wire to the required length plus some additional length for a service loop, then strip insulation back approximately ¼-inch. 6. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire. 7. Attach the ring terminal and black wire to the bare metal surface using stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten securely. 8. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface and around the ring terminal. 7.2.2.2 Red Wire and Main Fuse Holder Connection (Radio’s Main Power Wire) 1. Continue installation of the radio’s DC Power Cable by routing its 20-foot 10-AWG red wire to the location of the vehicle’s battery (or its main DC bus bar or stud). Remove interior panels, door kick panels, etc., and route the wire through existing channels in the vehicle body as necessary. Protect the wire from possible chafing where necessary. Tie and stow the wire as necessary. CAUTION Plan the routing of the 10-AWG red wire carefully, using an existing access hole in the vehicle’s firewall if possible. Alternately, drill a new hole approximately ½-inch in diameter and install a small rubber grommet (one supplied with the bracket kit) to protect the wire from chafing at the hole’s sharp metal edge. To prevent fumes from entering the passenger compartment, this hole/grommet/wire combination must also be sealed with a silicon-based sealer before completing the installation. CAUTION Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s engine. Excessive engine heat can cause permanent damage to these components and can lead to intermittent electrical connection to the battery. Before making connections to the battery’s positive post, carefully disconnect the battery’s negative (ground) cable(s). This will prevent tools or other metallic objects which come in contact with the battery’s positive terminal from shorting to vehicle ground, causing sparks or even a fire or an explosion! When disconnecting the negative cable(s), cover/insulate the positive post(s) if it is not already so a tool cannot short between the posts. Some vehicles, such as those with diesel engines have more than one battery; in this case, disconnect the negative cables at all batteries. Radio fuses should not be installed until all wiring is complete. This will prevent the radio from powering up prematurely and/or causing an in-rush of current that could lead to shorting of the battery, sparks, or even fire.
MM-014763-001, Rev. G 54 2. Obtain the orange waterproof (HFB type) fuse holder included with the DC Power Cable. 3. Observe and follow the previously presented WARNING! 4. Cut the red wire to the required length for connection to the battery’s positive (+) battery terminal (or the main DC bus bar or stud). 5. Prepare to splice the fuse holder into the red wire by cutting it again, at approximately three (3) to six (6) inches from the end. 6. Strip all three (3) wire ends back approximately ⅜-inch, place a fuse holder shell on each wire, and securely crimp a fuse holder terminal to each wire end. Before crimping, verify fuse holder shells are oriented in the correct directions (i.e., with each large end towards the wire end). 7. Label this fuse holder and red wire appropriately (e.g., “M7300 Main Power: 15-AMP FUSE”). 8. Do NOT install a fuse into the fuse holder at this time. 9. Crimp an appropriate electrical terminal to the short red wire. A corrosion-resistant ⅜-inch ring terminal is included with the cable for this purpose, but another size corrosion-resistant terminal type (not supplied) may be used if required. 10. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s main/non-switched power distribution terminal block). A front-mount M7300 mobile radio installation may be equipped with additional CH-721 control heads in a multi-head installation. In this case, refer to Section 8.3 (begins on page 67) for control head installation procedures. 7.2.2.3 White Wire Connection A review of the information presented in Section 7.2.1 (page 51) may be beneficial at this time. As required per the chosen power-up configuration, connect the white wire by following one of the three procedures presented in the respective sub-section that follows. 7.2.2.3.1 Radio Turns On and Off with Vehicle’s Ignition Switch/Key With this wiring configuration, the radio (and its control head) automatically turns on and off with the vehicle’s ignition switch/key. The white wire is sometimes referred to as the “white ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire connects to a switched power source, typically identified as “Accessory” power, that switches on and off with the vehicle’s ignition switch/key. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. The white ignition sense wire must be connected to a fused power source that switches from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition switch/key is turned from the OFF position to the ACCESSORY and RUN positions. Use of a switched power source that is subject to voltage changes as a result of other actions, such as opening a vehicle door, may result in undesirable radio power cycles. 1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s fuse panel. It may be necessary to consult the vehicle manufacturer’s wiring diagram. 2. Route the white wire of the radio’s DC Power Cable from the back of the radio to the area near this connection point. Protect the wire from possible chafing as necessary.
MM-014763-001, Rev. G 55 3. Obtain the other waterproof (HFB-type) fuse holder included with the radio’s DC Power Cable. 4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the connection point. 5. Using an appropriate electrical terminal, connect the white wire to the switched power connection point. An open-barrel spade terminal is included with the cable for this purpose, but another type of terminal (not supplied) may be used as required. 6. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder. 7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is avoided. 8. Continue with the speaker installation procedures presented in Section 9.1 on page 84. 7.2.2.3.2 Radio Turns On and Off with a Manual Switch With this wiring configuration, the radio (and its control head) is manually turned on and off via an on/off switch mounted separately from the radio, not through the vehicle’s ignition switch/key. This configuration is used when, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable and/or required. In this configuration, the white wire connects to a fused switched power source such as that provided by a toggle switch mounted on the vehicle’s dash panel. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. 1. Route the white wire of the radio’s DC Power Cable from the back of the radio to an area near the location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary. 2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends. 3. Obtain the other waterproof (HFB-type) fuse holder included with the radio’s DC Power Cable, and crimp one half of it to one end of the short section of wire. 4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC power source at or near the vehicle’s fuse box. 5. Cut another section of white wire from the cable. This wire must be long enough to reach from the fuse holder to the location of the panel-mounted on/off switch. 6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end. 7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common terminal of the switch. 8. Connect the white wire of the power cable to the load (switched) side of the switch. 9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location. 10. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder. 11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe is avoided. 12. Label this power switch accordingly. For example: “RADIO ON/OFF.” 13. Continue with the speaker installation procedures presented in Section 9.1 on page 84. 7.2.2.3.3 Radio Is “Hot Wired” In the “hot-wired” configuration, the radio (and its control head) is turned on and off only by the control head’s on/off/volume control located on the front panel of the control head. In this configuration, the
MM-014763-001, Rev. G 56 white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the procedure presented in Section 7.2.2.3.1, except connect the white wire to unswitched battery power instead of switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line fuse holder and 3-amp AGC fuse. 7.3 TERMINATE CAN PORTS Add a CAN Terminator to each CAN port connector on the rear of the radio. Two (2) CAN Terminators are included in the installation kit for this purpose (item 3 in Table 4-4).
MM-014763-001, Rev. G 57 8 REMOTE-MOUNT RADIO INSTALLATION This section includes detailed instructions for mechanically installing and wiring a remote-mount M7300 mobile radio. For front-mount M7300 mobile radio installation procedures, refer to Section 7 which begins on page 47. 8.1 MOUNTING THE REMOTE-MOUNT RADIO This section provides details on mounting a remote-mount M7300 mobile radio in the vehicle. CH-721 control head installation procedures are included in Section 8.3 which begins on page 67. HHC-731 hand-held controller installation procedures are included in Section 8.4 which begins on page 77. As an assembled unit, the radio weighs approximately 8 pounds (3.63 kilograms). The preferred mounting of the radio is on top of a firm, flat surface. Radio dimensions are shown in Figure 8-1. Installation Kit MAMW-NZN7R (contents listed in Table 4-5 on page 27) contains the most complete set of materials for installing the remote-mount M7300 mobile radio. Therefore, the following instructions make repeated reference to this kit. Item numbers given in parenthesis refer to items in the kit. Prior to beginning the installation, verify the radio has the proper version of software and verify it has been configured properly for customer usage. Consult with the radio system network administration personnel as necessary. CAUTION Though generally mounted in a trunk or remote location, the remote-mount mobile radio must be kept away from heat sources. Mounting it in a location which is out of direct sunlight is recommended but not required. Adequate ventilation space must be provided to the side fins. The radio reduces its RF output power when its ambient temperature exceeds approximately +140 o Fahrenheit (+60o Celsius). At a minimum, the mounting surface should be 16-gauge (approximately 1/16-inch thick) steel sheet metal. Mounting to plastic or other material with low tensile and shear strength could lead to an unsafe and/or failed mounting condition, turning the radio and its mounting bracket into a projectile during a high-shock incident such as a motor vehicle accident. If the selected mounting surface does not meet the minimum 16-gauge steel sheet metal requirement, the surface should be reinforced with a metal backing plate (not supplied) or it should be reinforced using some other approved mounting method. CAUTION Before drilling holes and/or installing mounting screws, verify these operations will not damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the transmission housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. Always deburr drilled holes before installing screws.

MM-014763-001, Rev. G 59 8.1.1 Mounting Bracket Installation The remote-mount radio’s mounting bracket is included with the Remote-Mount Mounting Bracket Kit KT23117. Kit contents are shown in Figure 8-2. This kit is Item 1 listed in Table 4-5 (page 27). M5 Hardware for Mounting Bracket Securing Radio FM103111V1 to Bracket Figure 8-2: Remote-Mount Mounting Bracket Kit KT23117 Typically, the radio’s mounting bracket is mounted in the vehicle’s trunk, on the top surface of the trunk tray or on the trunk floor. However, it can be suspended from the trunk’s rear deck if the surface is completely flat and the thickness of deck’s sheet metal is adequate. When selecting a mounting location for the radio, verify sufficient clearance can be maintained around the radio for installation and service access. A minimum clearance of four (4) inches (approximately 10 centimeters) is recommended at the rear, left and right sides of the radio, and at least 2 inches (approximately 5 centimeters) of clearance is recommended at the front of the radio. As illustrated in Figure 8-3, the bracket is left-to-right symmetrical and the shortest portion of its side rails are at the rear. As installations differ, bracket-to-vehicle mounting screws are not included. Utilization of ¼-inch-diameter, 28-thread-per-inch (¼-28) stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) is highly recommended. However, ¼-inch stainless-steel self-drilling screws may be employed to speed installation time. Self-drilling screws such as “TEK” screws do not require drilling of a pilot hole prior to installation. Do not use common self-threading sheet metal screws because they will loosen over time with vehicle vibrations. The bracket has four (4) available mounting holes. All four must be used to secure the bracket to its mounting surface. The following mounting procedure is recommended: 1. Using the mounting bracket as a template, and/or the dimensional information shown in Figure 8-3, mark and drill four (4) mounting holes into the mounting surface as required per the type of hardware used. When the radio is installed in the bracket, it will extend approximately one (1) inch past the front edge bracket, and at the rear, it will extend approximately ½-inch past the rear edge of the bracket. This distance at the rear does not include space required for cable connections at the rear of the radio. As previously stated, a clearance of least four (4) inches (approximately 10 centimeters) at the rear of the radio is recommended. 2. Temporarily remove the bracket and deburr all of the newly drilled holes.
MM-014763-001, Rev. G 60 3. If necessary, apply an approved paint or rust-inhibitor at the holes in the mounting surface. 4. Set the bracket back into place, and verify front-to-rear orientation. 5. Install and tighten the mounting screws/hardware. 6. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable vibration, which could damage the radio and/or cause its cable connections to loosen.

MM-014763-001, Rev. G 61 8.1.2 Inserting the Radio into the Mounting Bracket The radio should now be inserted into the bracket according to this procedure: 1. Lay the radio down into the mounting bracket with the front of the radio at the front of the mounting bracket. 2. Attach the radio into the mounting bracket using the six (6) M5 x 10 mm stainless-steel hex-head screws, and flatwashers and lockwashers included with the Mounting Bracket Kit (item 1 in Table 4-5). Tighten all six screws using a 5/16-inch wrench (or a ¼-inch-drive ratchet with a 5/16-inch socket) until each lockwasher is fully compressed and the radio is firm and flush in between the brackets. 3. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an area to secure and stow the excess cable lengths. Proper mounting is one factor that ensures optimal radio performance. An improperly mounted radio may experience degradation in the quality of voice and data communications. 8.2 REMOTE-MOUNT RADIO’S DC POWER INSTALLATION Unless otherwise noted, references in the following subsections to the “control head” also apply to the hand-held controller. 8.2.1 Overview of On/Off Power Wiring Configurations Radio on/off power control is accomplished by the control head, except in the case of a data-only radio installation which has no control head. In a standard installation, when the control head is turned on, it “wakes-up” the radio via data activity on the CAN link. The following power wiring configurations are supported:  Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the radio. The white wire of the control head’s DC Power Cable is connected to a fused switched power source, typically identified as vehicle “Accessory” power. This source must switch on (up to positive (+) battery voltage potential) when the vehicle’s ignition switch/key turns on, and it must switch off (to near zero volts) when the ignition switch/key turns off. The required fuse rating is 3 amperes. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. In a remote-mount radio installation, to fuse the white wire of the control head’s DC Power Cable, a yellow waterproof (HFB type) fuse holder and a 3-amp AGC fuse are included with the cable.  Radio turns on and off with a manual switch — This configuration is used when, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable. The white wire of the control head’s DC Power Cable is connected to one side of a manually-controlled switch, and the other side of this switch is connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly.

MM-014763-001, Rev. G 64  Radio turns on with control head’s on/off/volume control (“hot wired”) — This configuration allows radio on/off power control only via the control head’s on/off/volume control. It may be desired if, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is not desired and/or not acceptable. The white wire of the control head’s DC Power Cable must be connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes. In all of the above cases, both the radio’s main DC power input (red wire) and the control head’s main DC power input (also a red wire) must each be connected through an in-line fuse to unswitched vehicle DC power. The red wire of the radio’s DC Power Cable must be connected to raw battery power (positive battery terminal) via the supplied fuse. Likewise, the red wire of the control head’s DC Power Cable must also be connected to unswitched vehicle DC power via another supplied fuse. The white ignition wire of the radio’s DC Power Cable is only used for the data-only radio (i.e., no control head), and it is the only means for turning its power on in the data-only radio installation. CAUTION Any DC input power provided to the radio shall be no higher or lower than 13.6 volts DC 10%. The DC input power should be free and clear of any AC noise or DC spikes above 18 volts. If the vehicle cannot meet these requirements, then DC conditioning will be required before any DC power is connected to the radio. This includes conditioning for both the radio’s main DC power input lead and for its switched ignition sense power input. DC conditioning can be accomplished by a noise filter or DC isolation equipment such as Harris part number FL-018314-001 or FL-018314-002, or similar units with equal specifications. The fuse must be placed in-line before any noise filter. Contact TAC for additional information. 8.2.2 DC Power Cable and Main Fuse Holder Installation The radio’s DC Power Cable has a 3-pin connector, a 20-foot red wire (for the main power connection), a 20-foot white wire (only connected in a data-only radio installation), and a 4-foot black wire (for the ground connection). It is supplied with waterproof fuse holders, two AGC-type fuses, and non-insulated ring terminals. The following installation procedures are recommended: 8.2.2.1 Black Wire Connection (Ground Wire) 1. Connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s 3-pin power cable connector as follows: Visually align the key and firmly push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm proper mating. CAUTION Do not confuse the radio’s DC Power Cable which has a 10-AWG red wire with the control head’s DC Power Cable which has a 12-AWG red wire. The radio requires much more DC operating current than the control head. Therefore, it requires the larger wire size of 10-AWG. The part number of the radio’s DC Power Cable is CA-012365-001. 2. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal within approximately two (2) feet of the radio. This surface must have a solid and stable connection to vehicle ground. If not, add grounding strap(s) as necessary. 3. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square. 4. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-insulated ring terminal is supplied with the cable to make this ground connection. Therefore, hole
MM-014763-001, Rev. G 65 diameter should be appropriate for the utilized grounding screw/bolt size and type used to connect the ring terminal to the bare metal surface. This hardware is not supplied. 5. Cut the black wire to the required length plus some additional length for a service loop, then strip insulation back approximately ¼-inch. 6. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire. 7. Attach the ring terminal and black wire to the bare metal surface using stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten securely. 8. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface and around the ring terminal. 8.2.2.2 Red Wire and Main Fuse Holder Connection (Radio’s Main Power Wire) 1. Continue installation of the radio’s DC Power Cable by routing its 20-foot 10-AWG red wire to the location of the vehicle’s battery (or its main DC bus bar or stud). Remove interior panels, door kick panels, etc., and route the wire through existing channels in the vehicle body as necessary. Protect the wire from possible chafing where necessary. Tie and stow the wire as necessary. CAUTION Plan the routing of the 10-AWG red wire carefully, using an existing access hole in the vehicle’s firewall if possible. Alternately, drill a new hole approximately ⅜-inch in diameter and install a small rubber grommet to protect the wire from chafing on the hole’s sharp metal edge. To prevent fumes from entering the passenger compartment, this hole/grommet/wire combination must also be sealed with a silicon-based sealer before completing the installation. CAUTION Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s engine. Excessive engine heat can cause permanent damage to these components and can lead to intermittent electrical connection to the battery. Before making connections to the battery’s positive post, carefully disconnect the battery’s negative (ground) cable(s). This will prevent tools or other metallic objects which come in contact with the battery’s positive terminal from shorting to vehicle ground, causing sparks or even a fire or an explosion! When disconnecting the negative cable(s), cover/insulate the positive post(s) if it is not already so a tool cannot short between the posts. Some vehicles, such as those with diesel engines have more than one battery; in this case, disconnect the negative cables at all batteries. Radio and control head fuses should not be installed until all wiring is complete. This will prevent the radio from powering up prematurely and/or causing an in-rush of current that could lead to shorting of the battery, sparks, or even fire. 2. Obtain the orange waterproof (HFB type) fuse holder included with the DC Power Cable. 3. Observe and follow the previously presented WARNING! 4. Cut the red wire to the required length for connection to the battery’s positive (+) battery terminal (or the main DC bus bar or stud).
MM-014763-001, Rev. G 66 5. Prepare to splice the waterproof fuse holder into the red wire by cutting it again, at approximately three (3) to six (6) inches from the end. 6. Strip all three (3) wire ends back approximately ⅜-inch each, place a fuse holder shell on each wire, and securely crimp a fuse holder terminal to each wire end. Before crimping, verify fuse holder shells are oriented in the correct directions (i.e., with each large end towards the wire end). 7. Label this fuse holder and red wire appropriately (e.g., “M7300 Main Power: 15-AMP FUSE”). 8. Do NOT install a fuse into the fuse holder at this time. 9. Crimp an appropriate electrical terminal to the short red wire. A corrosion-resistant ⅜-inch ring terminal is included with the cable for this purpose, but another size corrosion-resistant terminal type (not supplied) may be used if required. 10. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s main/non-switched power distribution terminal block). Most M7300 radio installations have one or more control heads connected to the radio. In an installation of this type, the white wire of the radio’s DC Power Cable requires no electrical connection. Rather than be cut from the cable, it is recommended that it be routed up to the vehicle’s fuse box, coiled, labeled, and stowed for possible future use. The white wire of the control head’s DC Power Cable is the radio installation’s ignition sense input for on/off power control of both the control head and radio. Radio on/off power control is accomplished by the control head. The control head “wakes-up” the radio via data activity on the CAN link. 8.2.2.3 White Wire Connection (for Data-Only Radio Installations) In the case of a data-only radio installation (i.e., no control head connected to the radio), the white wire of the radio’s DC Power Cable is used as the radio installation’s ignition sense input. Therefore, it requires electrical connection to a fused switched power source. The following procedure is recommended: 1. Route the 20-foot white wire of the radio’s DC Power Cable to the location of the vehicle’s switched power source connection point, typically identified as “Accessory” power. Remove interior panels, door kick panels, etc., and route the wire through existing channels in the vehicle body as necessary. Protect the wire from possible chafing where necessary. Tie and stow the wire as necessary. 2. Connect this white wire through a fuse to the switched power source in accordance with the instructions presented within the respective subsection of Section 8.3.4.2 (page 74) for the control head’s white wire. Follow the procedure in Section 8.3.4.2.1 (page 74) if the vehicle’s ignition switch/key must control the data-only radio’s on/off power. Follow the procedure in Section 8.3.4.2.2 (page 74) if a manually-controlled switch must control the data-only radio’s on/off power. The “hot wired” wiring configuration (as depicted in Section 8.3.4.2.3) cannot be utilized for the data-only radio, since this configuration does not employ the DC Power Cable’s white wire. 8.2.3 Additional Hook-Up Required for a Data-Only Radio Installation The CTLON (control power on) logic input of a data-only radio must be grounded per this procedure: 1. Obtain M5300/M7300 Option Cable CA-012349-001. 2. Connect this cable’s male DB-44 connector to the female DB-44 connector on the rear of the radio. Tighten the connector’s two (2) jackscrews firmly.
MM-014763-001, Rev. G 67 3. Using an appropriate DB-25 connector, hook-up wire, ring terminal and hardware (not supplied), connect pin 14 of this cable’s DB-25 connector (P4 pin 14) to vehicle ground. This grounds the radio’s CTLON input at pin 15 of the DB-44 connector. See Section 11.1 for additional information on the Option Cable. Keep the length of the ground wire as short as reasonably possible. 4. Tie and stow the cable and wire as necessary to protect them from possible cable chafing. CAUTION When servicing the radio and/or control head, always manually power-down the radio equipment via the control head’s on/off/volume control knob, and then remove the main power fuse near the battery. 8.3 CH-721 CONTROL HEAD INSTALLATION This section includes installation instructions for the CH-721 control head. If the radio is being installed with and connected to a HHC-731 hand-held controller, skip this section and advance to Section 8.4 which begins on page 77. 8.3.1 General Information The remote-mount M7300 mobile radio must be connected to a control head to provide the operator-to-radio interface. Two different control heads are available — the CH-721 Scan model and the CH-721 System model. See Figure 8-5 and Figure 8-6 respectively. The CH-721 Scan model control head features three (3) large menu selection buttons. The System model control head has a 12-button keypad to allow advanced operations without the need of a DTMF-capable microphone. Figure 8-7 on page 68 illustrates the rear panel of the two control head models. Both models have identical rear panels and rear panel connectors.

MM-014763-001, Rev. G 68 (Other controls are same as shown for Scan model.) Figure 8-6: CH-721 System Model Control Head Front Panel The CH-721 control heads feature a large easy-to-read 3-line graphical vacuum fluorescent display, an on/off/volume control knob, menu controls and buttons, trunking mode buttons, an emergency/home button, a scan on/off button, and three (3) preset buttons. Other front panel components include a microphone connector and LED-type indicators. One LED indicator is the busy indicator that lights when the radio is receiving a call and one is the transmitter-enabled indicator that lights when the radio is transmitting. The front panel also has an ambient light sensor for automatic display dimming. Figure 8-7: CH-721 Rear Panel (both control head models) Prior to installing the control head, verify it has the proper software version installed and verify it has been properly configured for customer use. Because Installation Kit MAMW-NZN7R contains the most complete set of materials for installing the radio and control head, the following instructions make repeated reference to items within this kit. Item numbers given in parenthesis refer to items in the kit as listed in Table 4-5 on page 27. 12-Button Keypad Clear ButtonMenu ButtonOption ButtonCAN Port Connectors(2 places)Speaker Audio ConnectorSerial Port Connector (DB-9)DC Power Connector Accessory Connector(DB-25) Note: Serial and Accessory connectors are shown without waterproof covers.
MM-014763-001, Rev. G 69 In a mobile installation, more than one control head can be connected to one mobile radio for multi-head installations. A multi-head installation may be required in a vehicle such as a fire truck or any large vehicle where more than one operator may require use of the radio. Multi-head installations also provide other benefits such as intercom functionality between different operator positions. 8.3.2 Control Head Mechanical Installation 8.3.2.1 Selecting the Mounting Location When selecting a location for the CH-721 control head, first observe the safety and operator-convenience related information presented in Section 5.1 on page 35. Always consider and include clearance for the microphone’s connector that must mate to the mic connector on the front panel of the head, and clearance for the connectors/cables that must mate to the connectors on the rear panel of the head. The CH-721 control head can be mounted under or on top of a mounting surface (typically the vehicle’s dash) as space permits using either the standard U-shaped mounting bracket or the optional mounting pedestal. Figure 8-8: Standard U-Shaped Control Head Mounting Bracket (Kit Part Number KT-008608) Mounting Bracket (Shown positioned above control head) Bracket shown attached to a CH-721 System model control head (Head is not included with Mounting Bracket Kit) Socket-Head Cap (Allen) Screw, Lockwasher and Flat Washer; 2 places each side (Included with kit)
MM-014763-001, Rev. G 70 Figure 8-9: Optional Control Head Mounting Pedestal (Part Number MACDOS0012) 8.3.2.2 Using the Standard U-Shaped Mounting Bracket If the standard U-shaped mounting bracket will be used to mount the control head, the following mounting procedure is recommended. As listed in Table 4-5 on page 27, this bracket is item 2 in the Installation Kit. 1. Using the mounting bracket as a template, mark and drill mounting holes into the mounting surface as required. The round and elliptical holes in the bracket’s vehicle mounting surface are symmetrical, so forwards/backwards positioning is not important during this step. However, positioning is important in the next step. CAUTION Before drilling holes and/or installing mounting screws, verify these operations will not damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the transmission housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. Always deburr drilled holes before installing screws. 2. Postion the bracket at the mounting surface so the two round holes in its two side “ears” are nearest to the normal location of the operator (typically towards the rear of the vehicle) and the two slotted holes are furthest from the normal location of the operator (typically towards the front of the vehicle). 3. Install and tighten the mounting screws. Screws for mounting the bracket to the mounting vehicle’s surface are not included, as all installations differ. Self-threading screws are recommended. Use of self-drilling screws may cause damage to some mounting surfaces, such as a plastic dash panel. 4. Verify the bracket is held firmly to the mounting surface. Firm mounting prevents unreasonable vibration, which could damage the control head and/or cause its cable connections to loosen. 5. Slide the control head into the bracket, placing the two pegs protruding from its left and right sides into the respective round holes in the bracket’s two side “ears.” 6. In each side “ear” of the mounting bracket, start a #8-32 hex-socket-head cap (Allen) head screw with a lockwasher and a flat washer by inserting the screw through the slotted hole in the bracket and then into the threaded hole in the side of the control head. This hardware is included with Mounting Control Head Mounting Pedestal MACDOS0012 (Pedestal can be attached to the bottom of the head (as shown) or it can be attached to the top of the head.) Pedestal shown attached to a CH-721 Scan model control head (Head is not included with Mounting Pedestal.) #8-32 Pan-Head Screw; 4places (Included withMounting Pedestal)For a “hanging” control headinstallation, the pedestal canbe attached to the top of thehead via threaded holes inthe top of the head’s case.This figure shows thepedestal attached to thebottom of the control head viathreaded holes in the bottomof the case.
MM-014763-001, Rev. G 71 Bracket Kit. The lockwasher should be adjacent to the screw head and the flat washer should be adjacent to the bracket. Turn each screw clockwise as observed from the head of the screw. 7. The control head can be positioned at various angles for best display viewing at the normal position of the operator. As necessary, turn it on the pegs to a good position and tighten both screws using an ⅛-inch hex key (Allen) wrench until the control head is held firmly in place. Do not over-tighten. 8.3.2.3 Using the Mounting Pedestal (Optional) An optional Mounting Pedestal, part number MACDOS0012, may be purchased separately to replace the standard U-shaped mounting bracket. This pedestal can be attached to the bottom of the control head as shown in Figure 8-9, and then mounted to a mounting surface below the two. It can also be attached to the top of the head and then mounted to a mounting surface above the two. 8.3.3 Control Head-to-Radio CAN Cable Connections 8.3.3.1 General Information A remote-mount radio installation requires a CAN cable between every two “CAN devices” and CAN terminators on each end of the CAN link. The M7300 mobile radio is considered a CAN device, and each CH-721 control head in the installation is also considered a CAN device. Figure 8-10 illustrates CAN cable and CAN terminator connections for a single control head installation. Figure 8-11 illustrates this for a multi-head control head installation where, for example, one control head is located at the main operator location and another is located near the rear of the vehicle. Because CAN devices do not have internal terminators, the CAN link must be terminated at both ends via external CAN terminators, as depicted in the following figures. For Available CAN Cable Lengths and Respective Part Numbers, see Table 4-8 on page 34. Figure 8-10: CAN Link Connections for a Single Control Head Installation
MM-014763-001, Rev. G 72 For Available CAN Cable Lengths and Respective Part Numbers, see Table 4-8 on page 34. Figure 8-11: Typical CAN Link Connections for a Multi-Control Head Installation Both the radio and the control head have two CAN ports to support “daisy-chaining” of multiple control heads or other CAN devices. Figure 5-3 on page 37 shows the radio’s two CAN port connectors, which are located near the center of the radio’s rear panel. Figure 8-7 on page 68 shows the two CAN port connectors on the control head’s rear panel. 8.3.3.2 Make CAN Link Terminations and Cable Connection Follow this procedure for an installation which has only one control head. For a multi-control head installation, refer to Figure 8-11 as necessary. 1. Mate a CAN Terminator (item 5 in Table 4-5 on page 27) with either one of the two smaller 3-pin CAN port connectors on the rear panel of the CH-721. This action makes the CAN termination at the control head end of the CAN link. When mating any CAN connection (terminators and cables) to a rear panel connector, visually align the ¾-moon-shaped keys of the connectors, and then gently push and turn the outer locking ring of the plug (male) connector clockwise until it stops. A mild click will be sensed to confirm proper mating. Without visual alignment as a guide, it is possible with excessive force to mate the CAN connectors improperly. Damage to the connector(s) may result. Therefore, visual alignment is recommended when mating CAN connectors. 2. Obtain a CAN Cable and mate it to the other CAN port connector on the rear panel of the CH-721. Typically, item 6 in Table 4-5 is utilized, a 30-foot CAN cable.
MM-014763-001, Rev. G 73 3. Route the cable through the vehicle’s interior wire/cable channeling to the radio. Remove interior panels, door kick panels, etc., as necessary. Protect the cable from possible chafing as necessary. 4. Mate this other end of the cable to one of the two CAN port connectors on the rear panel of the radio. 5. Mate another CAN Terminator to the other CAN port connector on the rear panel of the radio. This action makes the CAN termination at the radio-end of the CAN link. 6. Loop, tie and stow the excess cable as necessary, leaving a service loop at the back of the radio and at the back of the control head. 8.3.4 Control Head Power Cable Installation Plan the route of the control head’s DC Power Cable carefully. Do not route the cable where it will be damaged by heat sources or by casual contact, and protect it from wire chafe per standard installation methods. The following procedures are recommended: 8.3.4.1 Install DC Power Cable and Make Power and Ground Connections 1. Connect the control head’s DC Power Cable (item 4 in Table 4-5 on page 27) to the large 3-pin connector at the rear of the head. Visually align the key and gently push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm proper mating. 2. At the back of the control head, locate a nearby section of vehicle chassis ground and strip this area of any paint or dirt to expose a bare metal surface. 3. Cut the black wire of the control head’s DC Power Cable to the required length, plus a service loop of at least six (6) inches, then strip it and crimp a ⅜-inch ring terminal to it. Two ring terminals of this type are included with the cable. 4. Drill a hole as necessary and attach this ring terminal to chassis ground. Use stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten securely. 5. At the back of the control head, tie and stow the cable as necessary. 6. For the positive 12-volt DC main power source connection, route the cable’s red wire to the location of an unswitched 12-volt DC power source, typically near the vehicle’s battery. Remove interior panels, door kick panels, etc. Protect the wire from possible chafing as necessary. This is the control head’s main DC power source. 7. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC Power Cable. 8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the unswitched 12-volt DC power source connection point. 9. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A ⅜-inch ring terminal is included with the cable for this purpose, but another terminal type (not supplied) may be used if required. 10. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder. Do not share the control head’s fuse with any other device. Doing so can cause excess current to flow through the fuse, causing it to blow unnecessarily.
MM-014763-001, Rev. G 74 CAUTION The fuse for the control head’s red wire is rated at 5 amperes. The 3-amp fuse included with the cable must not be used for fusing the control head’s main DC power. It fuses the head’s white wire. 8.3.4.2 Connect DC Power Cable’s White Wire A review of the information presented in Section 8.2.1 (page 61) may be beneficial at this time. As required per the chosen power-up configuration, connect the white wire by following one of the three procedures presented in the respective sub-section that follows. 8.3.4.2.1 Control Head and Radio Turn on with Vehicle’s Ignition Switch/Key With this wiring configuration, the control head and radio automatically turn on and off with the vehicle’s ignition switch/key. The white wire of the control head’s DC Power Cable is sometimes referred to as the “white ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire connects to a switched power source, typically identified as “Accessory” power, that switches on and off with the vehicle’s ignition switch/key. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. The white ignition sense wire must be connected to a fused power source that switches from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition switch/key is turned from the OFF position to the ACCESSORY and RUN positions. Use of a switched power source that is subject to voltage changes as a result of other actions, such as opening a vehicle door, may result in undesirable radio power cycles. 1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s fuse panel. It may be necessary to consult the vehicle manufacturer’s wiring diagram. 2. Route the white wire of the control head’s DC Power Cable from the back of the head to the area near this connection point. Protect the wire from possible chafing as necessary. 3. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC Power Cable. 4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the connection point. 5. Using an appropriate electrical terminal, connect the white wire to the switched power connection point. An open-barrel spade terminal is included with the cable for this purpose, but another type of terminal (not supplied) may be used as required. 6. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder. 7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is avoided. 8.3.4.2.2 Control Head and Radio Turn On with a Manual Switch With this wiring configuration, the control head and radio are manually turned on and off via an on/off switch mounted separately from the control head and radio, not through the vehicle’s ignition switch/key. This configuration is used when, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable and/or required. In this configuration, the white wire connects to a fused switched power source such as that provided by a toggle
MM-014763-001, Rev. G 75 switch mounted on the vehicle’s dash panel. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. 1. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near the location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary. 2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends. 3. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC Power Cable, and crimp one half of it to one end of the short section of wire. 4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC power source at or near the vehicle’s fuse box. 5. Cut another section of white wire from the cable. This wire must be long enough to reach from this fuse holder to the location of the panel-mounted on/off switch. 6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end. 7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common terminal of the switch. 8. Connect the white wire of the power cable to the load (switched) side of the switch. 9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location. 10. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder. 11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe is avoided. 12. Label this power switch accordingly. For example: “RADIO ON/OFF.” 8.3.4.2.3 Control Head and Radio Are “Hot Wired” In the “hot-wired” configuration, the control head and radio are turned on and off only by the control head’s on/off/volume control located on the front panel of the control head. In this configuration, the control head’s white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the procedure presented in Section 8.3.4.2.1, except connect the white wire to unswitched battery power instead of switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line fuse holder and 3-amp AGC fuse. 8.3.5 Using Vehicle Fuse and T-Tap Kit (Optional) Instead of Waterproof Inline Fuse Holder (Standard) The waterproof inline fuse holder and AGC fuse included with the DC Power Cable must be used if the white wire connection point is located in a harsh environment such as in the vehicle’s engine compartment. In this case, disregard all information presented in this section, and follow one of the three procedures presented in Section 8.3.4.2 to connect the white wire. However, if the connection point is not in a harsh environment, such as under the vehicle’s dash panel, Vehicle Fuse and T-Tap Kit FS24473 may be ordered and used to make the white wire connection. As shown in Figure 8-12, this kit includes an ATM fuse holder and fuse, T-tap crimp terminals for tapping into an existing vehicle switched power wire, and a quick-disconnect terminal. The following installation procedure is recommended for this optional kit: 1. Locate the switched ignition or “Accessory” power wire (typically at or near the vehicle’s fuse block or in a vehicle wiring harness) that will be used for the switched ignition power source. It may be necessary to consult the vehicle manufacturer’s wiring diagram.
MM-014763-001, Rev. G 76 2. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near the switched ignition power source. At the back of the head, be sure to maintain a cable service length of at least six (6) inches and do not loop the cable. 3. Cut a short section (6 to 8 inches) off the end of the white wire and strip each end of this short wire.

From the Vehicle Fuse and T-Tap Kit, locate the male-tab quick-disconnect terminal and crimp it to one end the short wire. 5. From the same kit, locate the ATM fuse holder and crimp it to the other end of the short wire. The holder has built-in crimpable joints. 6. Cut the excess length from the white wire of the control head’s power cable, strip it, and crimp it to the other side of the ATM fuse holder. 7. Pull enough of the switched ignition source wire out of the vehicle’s wiring harness so one of the T-tap terminals may be attached to it. 8. Two T-tap terminals are included in the kit. Based on the gauge of wire, select the proper terminal size: Red is for connecting to a 22 to 18-AWG wire, and blue is for connecting to an 18 to 14-AWG wire. 9. Attach the selected T-tap terminal by fitting the wire into its wire groove and snapping the two halves together with a pair of pliers as shown in Figure 8-13. 10. Push the male-tab quick-disconnect terminal into the T-tap terminal’s inlet until it is fully engaged. 11. Install the 2-amp ATM fuse into the fuse holder. It is recommended that a piece of electrical tape be wrapped around the fuse connection to keep the fuse from being jostled out of the holder. 12. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe is avoided. Diagram Courtesy of 3M Corp.

MM-014763-001, Rev. G 77 8.4 HHC-731 HAND-HELD CONTROLLER INSTALLATION In a remote-mount M7300 mobile radio installation, the HHC-731 hand-held controller can be used in place of the CH-721 control head. This easy-to-use hand-held mobile radio controller is primarily designed for use in harsh environments such as maritime (i.e., boating) applications and All-Terrain Vehicle (ATV) applications. The HHC-731 hand-held controller has easy-to-use buttons, a tough liquid-crystal display (LCD), and a built-in microphone. As of the publication of this manual, only one (1) HHC-731 hand-held controller can be connected to a radio, and without any connected CH-721 control heads. The front of the HHC-731 hand-held controller is shown in Figure 8-14. Installation procedures for the HHC-731 hand-held controller are included in this section. Procedures include:  Mounting the HHC-731 Interface Cable and Bracket (see page 78);  Connecting CAN Link (see page 79);  Connecting DC Power (see page 80);  Mounting the HHC-731 Hanger (see page 82); and,  Connecting the HHC-731 to the HHC-731 Interface Cable (see page 83).

MM-014763-001, Rev. G 78 8.4.1 Mounting the HHC-731 Interface Cable and Bracket HHC-731 Interface Cable Mounting Bracket Kit KT-018752-001 is show in Figure 8-15. This kit includes Bracket FM-018681-001 and mounting hardware, which secure the HHC-731 Interface Cable to a mounting surface. In Table 4-6 and page 29, the bracket kit is item 3, and the cable is item 3. Figure 8-15: HHC-731 Interface Cable Mounting Bracket Kit KT-018752-001 Follow this procedure to attach the cable to the bracket, and to mount the bracket to a firm surface: 1. Attach the bracket to the large end of the cable using the two #6-32 machine screws and flatwashers included in the bracket kit. As illustrated in Figure 8-16, the two can be attached either perpendicular or parallel to each other. The “wings” of the bracket should be positioned away from the cable. Only two of four center-most holes in the bracket are used. 2. Tighten the two (2) screws securely with a #1 Phillips screwdriver. Do not over-tighten. Bracket Attached Bracket Attached Perpendicular to Cable: Parallel to Cable: Figure 8-16: HHC-731 Interface Cable Mounting Bracket-to-Cable Positioning 3. Select a firm mounting surface near the controller, for the bracket. Review and follow the safety and operator-convenience related information presented in Section 5.1 on page 35. Also, always consider and include clearance for the mating of the two connectors on each side of the square end of the cable, and for clearance for the two “pigtail” style cables extending from the bottom of the square end. 4. Using the four (4) corner holes of the mounting bracket as a template, mark and drill mounting holes into the selected mounting surface as required. CAUTION Before drilling holes and/or installing mounting screws, verify these operations will not damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the transmission housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. Always deburr drilled holes before installing screws.
MM-014763-001, Rev. G 79 5. Mount the mounting bracket and cable to the selected mounting surface using the thread-forming screws, lockwashers, and flatwashers included with the HHC-731 installation kit, or other screws as required per the mounting surface. Tighten the four screws securely, but do not over-tighten them. 6. Verify the mounting bracket is firmly mounted. Firm mounting prevents unreasonable vibration, which could damage the cable and/or cause its cable connections to loosen over time. 8.4.2 Connecting CAN Link Connect the CAN link between the radio’s CAN port and the CAN port connector of the HHC-731 Interface Cable in accordance with this procedure. Connections are illustrated in Figure 8-17: 1. Mate a CAN terminator to either one of the two small 3-pin CAN port connectors on the rear panel of the radio. The CAN terminator is item 7 in Table 4-6. 2. Obtain a CAN cable and mate it to the other CAN port connector on the rear panel of the radio. Typically, the 30-foot CAN cable is used, item 8 in Table 4-6. Other length CAN cables may be used, as listed in Table 4-8 on page 34. 3. Route the CAN cable through the vehicle’s interior wire/cable channeling to the radio. Remove interior panels, door kick panels, etc., as necessary. Do not route the cable where it will be damaged by heat sources or by casual contact. Protect the cable from possible chafing and other damage as necessary. 4. Mate the other end of the cable to the small 3-pin CAN port connector of the HHC-731 Interface Cable. 5. Loop, tie and stow the excess cable as necessary, leaving a service loop at the back of the radio and at the location of the interface cable. DB-25(F) Connector For Available CAN Cable Lengths and Respective Part Numbers, see Table 4-8 on page 34. Figure 8-17: M7300-to-HHC-731 CAN Link Connections
MM-014763-001, Rev. G 80 8.4.3 Connecting DC Power Plan the route of the DC Power Cable for HHC-731 hand-held controller carefully. Do not route it where it will be damaged by heat sources or by casual contact, and protect it from wire chafe per standard installation methods. The following procedures are recommended: 8.4.3.1 Install DC Power Cable and Make Power and Ground Connections 1. Connect the DC Power Cable (item 6 in Table 4-6) to the large 3-pin connector of the HHC-731 Interface Cable. Visually align the key and gently push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm proper mating. 2. Near the HHC-731 Interface Cable’s mounting location, locate a nearby section of vehicle chassis ground and strip this area of any paint or dirt to expose a bare metal surface. 3. Cut the black wire of the DC Power Cable to the required length, plus a service loop of at least six (6) inches, then strip it and crimp a ⅜-inch ring terminal to it. Two ring terminals of this type are included with the cable. 4. Drill a new hole as necessary and attach this ring terminal to chassis ground. Use stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten securely. CAUTION Do not ground the black wire by attaching it via the same hardware that secures the cable’s mounting bracket. CAUTION Before drilling holes and/or installing mounting screws, verify these operations will not damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the transmission housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. Always deburr drilled holes before installing screws. 5. Tie and stow the cable near the HHC-731 Interface Cable’s bracket. 6. For the positive 12-volt DC main power source connection, route the cable’s red wire to the location of an unswitched 12-volt DC power source, typically near the vehicle’s battery. Remove interior panels, door kick panels, etc. Protect the wire from possible chafing as necessary. This is the hand-held controller’s main DC power source. 7. Obtain one of the waterproof (HFB-type) fuse holders included with the DC Power Cable. 8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the unswitched 12-volt DC power source connection point. 9. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A ⅜-inch ring terminal is included with the cable for this purpose, but another terminal type (not supplied) should be used as required. 10. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder. Do not share the HHC-731 hand-held controller’s fuse with any other device. Doing so can cause excess current to flow through the fuse, causing it to blow unnecessarily.
MM-014763-001, Rev. G 81 CAUTION The fuse for the HHC-731 hand-held controller’s red wire is rated at 5 amperes. The 3-amp fuse included with the cable must not be used for fusing the controller’s main DC power. The 3-amp is used to fuse the controller’s white wire. 8.4.3.2 Connect DC Power Cable’s White Wire Connect the DC Power Cable’s white wire by following one of the following three procedures, per the customer’s required on/off power control method: 8.4.3.2.1 Hand-Held Controller and Radio Turn on with Vehicle’s Ignition Switch/Key With this wiring configuration, the HHC-731 hand-held controller and the radio turn on and off with the vehicle’s ignition switch/key (power on also requires pressing of the HHC-731’s front panel power on/off button). The white wire of the HHC-731’s DC Power Cable is sometimes referred to as the “white ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire of the HHC-731’s DC Power Cable connects to a switched power source, typically identified as “Accessory” power, that switches on and off with the vehicle’s ignition switch/key. The white ignition sense wire must be connected to a fused power source that switches from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition switch/key is turned from the OFF position to the ACCESSORY and RUN positions. Use of a switched power source that is subject to voltage changes as a result of other actions, such as opening a vehicle door, may result in undesirable radio power cycles. 1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s fuse panel. It may be necessary to consult the vehicle manufacturer’s wiring diagram. 2. Route the white wire of the HHC-731’s DC Power Cable to the area near this connection point. Protect the wire from possible chafing as necessary. 3. Obtain one of the waterproof (HFB-type) fuse holders included with the HHC-731’s DC Power Cable. 4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the connection point. 5. Using an appropriate electrical terminal, connect the white wire to the switched power connection point. An open-barrel spade terminal is included with the cable for this purpose, but another type of terminal (not supplied) may be used as required. 6. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder. 7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is avoided. 8.4.3.2.2 Hand-Held Controller and Radio Turn On with a Manual Switch With this wiring configuration, the HHC-731 hand-held controller and radio are turned on and off via an on/off switch mounted separately from the HHC-731 and radio, not through the vehicle’s ignition switch/key (power on also requires pressing of the HHC-731’s front panel power on/off button). This configuration is used when, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable and/or required. In this configuration,
MM-014763-001, Rev. G 82 the white wire of the HHC-731’s DC Power Cable connects to a fused switched power source such as that provided by a toggle switch mounted on the vehicle’s dash panel. 1. Route the white wire of the HHC-731’s DC Power Cable to an area near the location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary. 2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends. 3. Obtain one of the waterproof (HFB-type) fuse holders included with the HHC-731’s DC Power Cable, and crimp one half of it to one end of the short section of wire. 4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC power source at or near the vehicle’s fuse box. 5. Cut another section of white wire from the cable. This wire must be long enough to reach from this fuse holder to the location of the panel-mounted on/off switch. 6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end. 7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common terminal of the switch. 8. Connect the white wire of the power cable to the load (switched) side of the switch. 9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location. 10. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder. 11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe is avoided. 12. Label this power switch accordingly. For example: “RADIO ON/OFF.” 8.4.3.2.3 Hand-Held Controller and Radio Are “Hot Wired” In the “hot-wired” configuration, the HHC-731 hand-held controller and radio are turned on and off only by the on/off button on the front of the HHC-731. In this configuration, the HHC-731’s white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the procedure presented in Section 8.4.3.2.1, except connect the white wire to unswitched battery power instead of switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line fuse holder and 3-amp AGC fuse. 8.4.4 Mounting the HHC-731 Hanger A HHC-731 hanger is provided with the HHC-731 hand-held controller. Follow this procedure to mount the hanger: 1. Select a mounting surface location that will position the HHC-731 within easy reach of the radio operator’s location. Consult with the customer as necessary. Also review the information presented in Section 5. The selected location must have sufficient clearance for the HHC-731 when it is hung in the hanger. 2. Using the hanger as a template, drill mounting holes in the surface of the selected location. Use self-locking hardware (i.e., machine screws with washers and locking nuts), self-drilling screws, or other appropriate hardware as necessary. Tighten securely. 3. Stow the HHC-731 in the hanger and verify it can be easily inserted and removed. A spring detent action keeps the HHC-731 firmly stowed.
MM-014763-001, Rev. G 83 8.4.5 Connecting the HHC-731 to the HHC-731 Interface Cable 1. Mate the HHC-731’s female DB-25 connector to the male DB-25 connector of the HHC-731 Interface Cable. Tighten the two jackscrews securely, but do not over-tighten them. 2. If not already, tie and stow the HHC-731 Interface Cable. 3. Hang the HHC-731 in its hanger.
MM-014763-001, Rev. G 84 9 SPEAKER INSTALLATION 9.1 FRONT-MOUNT RADIO INSTALLATION In a front-mount radio installation, total speaker cable length (of both cables) is approximately 10 feet (308 centimeters). Therefore, to include service loops in these cables, the speaker must be mounted within approximately 9.5 feet (290 centimeters) of the M7300 mobile radio. 1. Select a location for the speaker that will allow for proper listening range with a moderate volume setting. 2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker’s part number, see Table 4-4 (page 26). 3. Route the speaker cable to the rear of the M7300 mobile radio. 4. Connect the M5300/M7300 Option Cable CA-012349-001 (item 5 in Table 4-4) to the DB-44 connector on the rear of the radio. Tighten the cable’s two (2) jackscrews securely. See Section 11.1 for additional information on this cable. 5. Mate the Option Cable’s 2-pin connector (identified P2) to the 2-pin connector on the end of the speaker cable. A mild click will be sensed to confirm proper mating. 6. Route the cables out of the way of casual contact. Tie and stow as necessary. 9.2 REMOTE-MOUNT RADIO INSTALLATION 9.2.1 With CH-721 Control Head In a remote-mount mobile radio installation with the CH-721 control head, an audio amplifier in the CH-721 control head drives the external speaker. For this case, total speaker cable length of both cables between the control head and speaker is approximately five (5) feet. Therefore, to include service loops in these cables, the speaker must be mounted within approximately 4.5 feet of the installation’s CH-721 control head. 1. Select a location for the speaker that will allow for proper listening range with a moderate volume setting. 2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker’s part number, see Table 4-5 (page 27). 3. Route the speaker cable to the rear of the CH-721 control head. 4. Mate the 6-inch speaker cable (item 8 in Table 4-5) to the 2-pin connector at the rear of the control head by visually aligning the ¾-moon-shaped keys of the connectors, and then pushing and turning the outer locking ring of the cable connector clockwise until it stops. A mild click will be sensed to confirm proper mating. 5. Connect the speaker cable’s 2-pin plastic connector to the respective mating connector on the 6-inch speaker cable. 6. Route the cables out of the way of casual contact. Tie and stow as necessary.
MM-014763-001, Rev. G 85 9.2.2 With HHC-731 Hand-Held Controller In a remote-mount mobile radio installation with the HHC-731 hand-held controller, an audio amplifier in the mobile radio drives the external speaker. The HHC-731 does not have a high-power speaker audio amplifier. The following speaker installation procedure is recommended for this case: 1. Obtain the speaker, item 9 in Table 4-6. 2. Select a location for the speaker that will allow for proper listening range with a moderate volume setting. 3. Install the speaker using the hardware and mounting bracket supplied with it. 4. If no other optional connections are required at the back of the radio, obtain Speaker Only Option Cable CA-012349-007. This cable is item 10 in Table 4-6. It is approximately 20-feet long. However, if other optional connections are required at the back of the radio (such as GPS NMEA-formatted serial data connections), obtain M5300/M7300 Option Cable CA-012349-001. This cable is approximately 5.5-feet long. In this case, the length of the cable’s 2-wire speaker leads may not be sufficient to reach the 2-pin speaker connector of the option cable, and they will need to be lengthened using approved splicing techniques. 5. Connect the option cable to the DB-44 connector on the rear of the radio. Tighten the two jackscrews securely, but do not over-tighten them. 6. Route the option cable’s 2-wire speaker lead to the 2-pin connector of the speaker cable. 7. Mate the option cable’s 2-pin connector to the 2-pin connector of the speaker cable. 8. After mating the two 2-pin connectors, secure them together with nylon tie wrap so they will not disconnect with vehicle vibrations or other movements. 9. Route the cables out of the way of casual contact. Tie and stow as necessary.
MM-014763-001, Rev. G 86 10 MICROPHONE ATTACHMENT There are several versions of microphones available for use with the radio. Each has a 17-pin flush-mount type connector that mates with the mic connector on the front panel of the control head. The mic’s connector includes a captive thumbscrew that secures it to the mic connector on the front panel of the control head. A microphone clip is included with each microphone. The radio can be configured to provide a monitor function when the microphone is cradled in the clip. Connect the mic to the control head and install the clip as follows: 1. As illustrated in Figure 10-1, grasp the mic’s connector with a thumb and index finger on the sides of the connector just adjacent to the thumbscrew. 2. Position connector just in front of the control head’s mic connector so its male pins can engage straight into the female (socket) pins of the control head’s mic connector. The thumbscrew must be oriented directly above the hanging mic cable. 3. Mate the two connectors by pressing them fully together. Do not apply any force to the thumbscrew when mating the connectors. 4. Tighten the thumbscrew finger-tight. Do not use a screwdriver to tighten it. 5. Using the microphone clip as a template, drill mounting holes in the surface of the selected location. 6. Select a mounting surface location that has clearance for the mic when it is clipped to the clip, and then attach the microphone clip to the surface. Use self-locking hardware (i.e., machine screws with washers and locking nuts), self-drilling screws, or other appropriate hardware as necessary. Tighten securely. Microphones used with the CH-721 control head have integrated hookswitches. Therefore, the microphone clip does not need to be grounded. 7. Clip the microphone to the clip. Figure 10-1: Attaching the Microphone to the CH-721Control Head As illustrated, do not apply anyforce to the thumbscrew whenmating the mic connectors.
MM-014763-001, Rev. G 87 11 OPTIONAL CABLES 11.1 M5300/M7300 OPTION CABLE CA-012349-001 M5300/M7300 Option Cable CA-012349-001 connects to the 44-pin I/O connector on the rear of the radio. It breaks out into several smaller standardized connectors, allowing straightforward access to external I/O interfaces provided by the radio. The cable also shortens radio removal and re-installation time when required. The cable is shown in Figure 11-1 below. The cable’s 44-pin D-subminiature connector that mates with the connector on the rear of the radio is identified P1. P2, the cable’s 2-pin connector, provides connections for an external speaker in a front-mount M7300 mobile radio installation, or in a remote-mount radio installation with a HHC-731 hand-held controller. For connection information, see Section 9.1 and Section 9.2.2 respectively. P2 is not used in a remote-mount radio installation with a CH-721 control head, since the audio amplifier in the head drives the external speaker (speaker connection is made at the rear of the control head). P3, the cable’s 6-pin connector, is a connector for basic accessories (e.g., hookswitch, etc.). P4, the cable’s D-subminiature 25-pin connector, provides audio and data connections for optional equipment such as an external siren and light system (e.g., Federal Signal SS2000 SmartSiren®).

MM-014763-001, Rev. G 96 12 GPS NMEA-FORMATTED SERIAL DATA CONNECTION To obtain GPS NMEA-formatted serial data from the radio, M5300/M7300 Option Cable CA-012349-001 is required. In addition, the radio must be equipped with the GPS receiver option. Follow this procedure to complete the GPS NMEA-formatted serial data connections: 1. Obtain M5300/M7300 Option Cable CA-012349-001. Each “leg” of this cable is approximately 65 inches long (166 centimeters). 2. Connect the cable’s 44-pin D-subminiature (DB-44) male connector to the DB-44 female connector on the rear panel of the radio. Tighten the two jackscrews with a small flathead screwdriver. Do not over-tighten. 3. Connect the cable’s DB-9 female connector to the computer’s serial port DB-9 male connector—either directly or extended via serial cable CA-013671-020 (a 20-foot-lon cable); see Section 11.2. Tighten the screws firmly, and then route the cabling as required. If the computer is not equipped with a DB-9 serial port connector, the use of a suitable adapter is required, such as USB-to-RS-232 Adapter Cable CN24741-0001. 4. Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the radio. If the M5300/M7300 Option Cable is not available, a 3-wire serial cable can be field-fabricated. On the radio end, this cable must interface to the three GPS-related signals of the radio’s 44-pin I/O Cable connector (pins 7, 31 and 32). See Table 11-1 for additional information. Industry software to process GPS information through this interface is not supported by Harris.
MM-014763-001, Rev. G 97 13 INITIAL POWER-UP TEST 1. At the radio’s main waterproof (HFB-type) fuse holder installed near the vehicle battery, insert the 15-amp AGC-type fuse that was included with the radio’s DC Power Cable. 2. Tie and stow all fuse holders at this location to prevent excess vibration/movement. 3. Carefully reconnect the vehicle’s battery ground cable. 4. If not already, temporarily connect the mobile antenna cable from the vehicle-mounted mobile antenna to the female TNC RF connector on the rear panel of the radio. This is a temporary connection until test procedures in Section 14 are complete. 5. If the radio is equipped with the GPS receiver option, permanently connect the antenna cable from the GPS antenna (or mobile/GPS combo antenna) to the female SMA connector on the rear panel of the radio. The male SMA connector on most GPS antenna cables has a 5/16-inch hex collar, so the use of a wrench of this same size is normally required for tightening. However, some may have collars with only knurled surfaces, so a standard wrench or torque wrench cannot be used. In either case, do not over tighten the connector and do not twist the cable when tightening. 6. If the installation is wired so the vehicle’s ignition key/switch turns the radio on and off, turn the switch to the Accessory or Run position. 7. If the control head is not already powered up, do so by rotating its on/off/volume control clockwise out of the detent position. For the HHC-731, press the on/off power button located just above the display. 8. Verify the control head/hand-held controller has powered-up by observing its display. If the display is not functioning, refer to Section 8.2.1 as necessary. Unlike many mobile radio products, the radio powers-up to the state of last control. As long as the software configuration parameters have been loaded, successful installation is almost immediately realized:  After a short boot-up sequence, the control head/hand-held controller displays login information and/or a talk group.  If no errors are displayed, the installation is most-likely properly wired.  If an error is displayed, recheck all cable connections, verify all fuses are properly installed, and verify battery power on the load side of the fuses, etc. If problems persist, contact the Technical Assistance Center (see page 23).  Consult the Operator’s Manual for operational information. Refer to Section 14 for performance test information.
MM-014763-001, Rev. G 98 14 PERFORMANCE TESTS This section includes procedures to verify the performance of the installation’s mobile antenna system. There are three (3) procedures in this section:  Changing Operating Mode for Tests  Testing by Transmitting into a Dummy Load (a 50-Ohm RF Terminator)  Testing by Transmitting into the Mobile Antenna CAUTION The accuracy of test results depends upon a DC power source in the range of 13.6 volts DC 10%, with a current capacity of greater than 15 amps. Make sure the vehicle’s battery is fully charged by running the engine for a few minutes before the test, and keep the engine running during the test procedures. Abide by the following WARNING! If the vehicle’s engine must remain running, the vehicle location should be well ventilated so exhaust fumes from the engine do not cause harm! CAUTION If a vehicle equipped with this radio requires jump-starting, the radio installation’s main AGC fuse (15-amp) should be removed from the holder prior to jump-starting. Doing so will prevent damage to the radio system. Prior to installation, the radio’s power level should be configured appropriately. The wide range of power levels indicated in the following procedures takes into account such things as: customer’s requirements; measurement errors, especially to include uncalibrated equipment; cabling losses; and voltage and temperature variations. By no means should the result from Performance Testing in this section be construed as the exact value of power level output from the radio, as the value is set and more accurately measured in the factory. The values obtained in these test procedures determine a successful installation only. 14.1 CHANGING OPERATING MODE FOR TESTS To complete tests in this section, placing the radio in a conventional mode and using an average-responding wattmeter to measure RF transmit power is recommended. However, if the radio is not programmed for conventional mode operations (i.e., OpenSky Trunking Protocol (OTP) mode is available but EDACS/Conventional/P25 (ECP) modes are not), tests will require a peak-reading RF wattmeter to measure RF transmit power. To select either conventional or OpenSky mode, use one of the following procedures: 14.1.1 Changing from OpenSky to Conventional This procedure assumes the control head/hand-held controller is configured with default keypad mapping. 1. Apply power to the radio and turn it on via the On/Off/Volume Control on the CH-721 control head. See Figure 8-5. For the CH-731 hand-held controller, use the On/Off Power Button located just above its display. See Figure 8-14.
MM-014763-001, Rev. G 99 2. For the control head, use the / Ramp Control to scroll through the menu until Mode Menu appears in the display. For the hand-held controller, use the Ramp Up Button or Ramp Down Button located on the top of the controller to scroll through the menu until Mode Menu appears in the display. 3. For the control head, select an available conventional channel/system via the +/- Ramp Control. For the hand-held controller, use the 6 (ADD) or 9 (DEL) keys on the keypad to select an available conventional channel/system. 4. For the control head, confirm the selection by pressing the MENU button, then toggling the Ramp Control once (to select Y for Yes), followed by pressing the MENU button again. The radio will enter the selected mode as indicated by the display. For the hand-held controller, confirm the selection by pressing the Menu Button (M), then the Ramp Up Button or Ramp Down Button, and then the Menu Button (M) again. 5. For the control head, select a conventional channel for test transmissions using the System/Group/-Channel Selection Control. For the hand-held controller, select a conventional channel for test transmissions using the  (up arrow) button or the  (down arrow) button located just below the display. 14.1.2 Changing from Conventional to OpenSky This procedure assumes the control head/hand-held controller is configured with default keypad mapping. 1. Apply power to the radio and turn it on via the On/Off/Volume Control on the CH-721 control head; see Figure 8-5. For the CH-731 hand-held controller, use the On/Off Power Button just above its display; see Figure 8-14. 2. For the control head, use the / Ramp Control to scroll through the menu until the required OpenSky system’s name is displayed. For the hand-held controller, use the Ramp Up Button or Ramp Down Button located on the top of the controller to scroll through the menu until the required OpenSky system’s name is displayed. 3. After a few seconds, the radio will automatically transition to OTP mode for operations on the selected OpenSky system. 4. If the radio is not programmed for auto-login, login to the OpenSky system. For login instructions, refer to the respective operator’s manual or quick guide as necessary. The quick guide is included with the radio when it ships from the factory. 5. For the control head, select a talk group for test transmissions using either the / Ramp Control or the System/Group/Channel Selection Control (required control per programming). For a hand-held controller, select a talk group for test transmissions using the  (up arrow) button or the  (down arrow) button located just below the display.

Vehicle-Mounted Antenna Tests are performed with the vehicle-mounted antenna per the installation described in Section 6 of this manual. 14.3 TRANSMITTING INTO A DUMMY LOAD 1. Using the Type N male to TNC male RF coaxial jumper cable, connect the radio’s antenna connector to the wattmeter’s input connector. Refer to Figure 14-1 as necessary. 2. Connect the 50-ohm dummy load to the wattmeter’s output connector, in place of the antenna cable from the vehicle-mounted antenna. As previously stated, if conventional mode is not available per radio programming (i.e., OTP mode is available but ECP mode is not), a peak-reading RF wattmeter is required to measure RF transmit power. Otherwise, the use of an average-responding wattmeter is recommended. See Table 14-1. 3. If not already, turn the radio on and set it to the required operating mode (based upon available radio programming and test equipment). Refer to Section 14.1 as necessary. 4. Set the radio to a test talk group or conventional channel, if available. It is recommended that a test talk group/channel be allocated for this testing. This same group should be used during the antenna test procedure which is presented in the subsequent section. or
MM-014763-001, Rev. G 101 Figure 14-1: Wattmeter Connections for Antenna System Tests 5. Position the wattmeter’s slug to measure forward RF output power. Rotate it if necessary. The arrow on the face of the slug must point away from the radio and towards the dummy load for forward power measurements. 6. For conventional mode transmissions, set the wattmeter to measure average RF power. For OpenSky mode transmissions, set the wattmeter to measure peak RF power. 7. Key the radio’s transmitter via the microphone’s PTT button. 8. For a VHF band transmission, compare the wattmeter’s reading with the target RF output power range of between 39.8 and 63 watts (50 watts ±1 dB). This transmit output power range assumes the radio is currently configured for high-power transmit. For a 700 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 15.1 and 23.9 watts (19 watts ±1 dB). This transmit output power range assumes the radio is currently configured for high-power transmit. For an 800 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 27.8 and 44.1 watts (35 watts ±1 dB). This transmit output power range assumes the radio is currently configured for high-power transmit. Transmit only for as long as needed to take the measurement, then immediately disable the transmission. 9. If the wattmeter reading is within the range, record the measured value in the appropriate space on the data collection form near the end of this manual. If the wattmeter reading is outside the range, verify the radio’s power supply voltage (i.e., battery voltage) is within the specified range, recheck all connections and measure the RF output power again. If this fails to produce a reading within the range, replace it and repeat this procedure. If problems persist, contact the Technical Assistance Center (see page 23).
MM-014763-001, Rev. G 102 14.4 TRANSMITTING INTO THE MOBILE ANTENNA 1. Connect the antenna cable from the vehicle-mounted antenna to the wattmeter as shown in Figure 14-1. 2. If not already, turn the radio on and set it to the required operating mode (based upon available radio programming and test equipment). Refer to Section 14.1 as necessary. 3. Set the radio to a test talk group or conventional channel, if available. It is recommended that a test talk group/channel be allocated for this testing. Otherwise, interference with other radio users in the system may occur. Also, during transmissions, always observe the RF exposure-related safety information presented in Section 1.2 (begins on page 7). 4. Position the wattmeter’s slug to measure forward RF output power. Rotate it if necessary. The arrow on the face of the slug must point away from the radio and towards the antenna for forward power measurements. 5. For conventional mode transmissions, set the wattmeter to measure average RF power. For OpenSky mode transmissions, set the wattmeter to measure peak RF power. 6. Key the radio’s transmitter via the microphone’s PTT button. 7. For a VHF band transmission, compare the wattmeter’s reading with the target RF output power range of between 39.8 and 63 watts (50 watts ±1 dB). This transmit output power range assumes the radio is currently configured for high-power transmit. For a 700 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 15.1 and 23.9 watts (19 watts ±1 dB). This transmit output power range assumes the radio is currently configured for high-power transmit. For an 800 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 27.8 and 44.1 watts (35 watts ±1 dB). This transmit output power range assumes the radio is currently configured for high-power transmit. Transmit only for as long as needed to take the measurement, then immediately disable the transmission. 8. If the wattmeter reading is within the range, record the value in the appropriate space on the data collection form near the end of this manual. If the wattmeter reading is outside the range, verify the radio’s power supply voltage (i.e., battery voltage) is within the specified range, recheck all connections, and measure the forward power again. If the installation employs a ¼-wave unity-gain antenna, observe the following NOTE. If these checks/corrections fail to produce a reading within the range, check all cabling and connections and repeat the testing procedure to this point. In the event the wattmeter reading still falls outside the range, replace the antenna, make sure all connections are seated firmly, and repeat the testing procedure. If problems persist, contact the Technical Assistance Center (see page 23).
MM-014763-001, Rev. G 103 If the mobile radio installation employs a ¼-wave unity-gain antenna (part number AN102800V1 or AN102800V2), the driven element (i.e., whip) of the antenna must be trimmed to the proper length in order to minimize antenna system VSWR. Refer to the instructions included with the antenna for trimming instructions. 9. Position the wattmeter’s slug to measure reverse (reflected) RF power from the antenna. The arrow on the face of the slug must point away from the antenna and to the radio to measure reverse power. 10. Key the radio’s transmitter via the microphone’s PTT button. 11. Compare the wattmeter reading with the RF power output range of 2 watts or less. Transmit only for as long as needed to take the measurement, then immediately disable the transmission. 12. If the wattmeter reading is within the range, record the value in the appropriate space on the data collection form near the end of this manual. If the wattmeter reading is outside the range, make sure the antenna is consistent with the specified frequency range of the radio. Recheck all antenna connections, and measure the reverse power again. If the installation employs a ¼-wave unity-gain antenna, observe the NOTE that immediately follows step 8. If these checks/corrections fail to produce a reading within the range, replace the antenna and repeat the entire antenna test procedure. Any value exceeding the maximum allowable reflected power value will result in a diminished RF output signal. If problems persist, contact the Technical Assistance Center (see page 23). 13. Disconnect the coaxial cable jumper and wattmeter. 14. Permanently connect the cable from the vehicle-mounted antenna to the radio’s antenna cable by mating the two TNC connectors together. Use two pairs of soft-jaw pliers to gently tighten this connection. Do not over tighten and do not twist either cable. 15. Make several test calls on the radio system to verify operation of the mobile radio. Before making the calls, select other talk groups or conventional channels, as required to verify operation. To prevent RF leakage and ensure peak performance, make sure the RF connectors are tight, but do not over-tighten so connector damage will not occur. Improper installation of the RF cables may lead not only to poor radio performance but also to harmful exposure to RF electromagnetic energy. Testing is complete. The radio is now ready for normal communications.

MM-014763-001, Rev. G 107 17 WARRANTY A. Harris Corporation, a Delaware Corporation, through its RF Communications Division (hereinafter "Seller") warrants to the original purchaser for use (hereinafter "Buyer") that Equipment manufactured by or for the Seller shall be free from defects in material and workmanship, and shall conform to its published specifications. With respect to all non-Seller Equipment, Seller gives no warranty, and only the warranty, if any, given by the manufacturer shall apply. Rechargeable batteries are excluded from this warranty but are warranted under a separate Rechargeable Battery Warranty (ECR-7048). B. Seller’s obligations set forth in Paragraph C below shall apply only to failures to meet the above warranties occurring within the following periods of time from date of sale to the Buyer and are conditioned on Buyer’s giving written notice to Seller within thirty (30) days of such occurrence: 1. for fuses and non-rechargeable batteries, operable on arrival only. 2. for parts and accessories (except as noted in B.1), ninety (90) days. 3. for P7300, P7200, P7100IP, P5400, P5300, P5200, P5100, P3300, M7300, M7200 (including V-TAC), M7100IP, M5300 and M3300 radios, two (2) years, effective 10/01/2007. 4. for Unity® XG-100P, three (3) years. 5. for all other equipment of Seller’s manufacture, one (1) year. C. If any Equipment fails to meet the foregoing warranties, Seller shall correct the failure at its option (i) by repairing any defective or damaged part or parts thereof, (ii) by making available at Seller’s factory any necessary repaired or replacement parts, or (iii) by replacing the failed Equipment with equivalent new or refurbished Equipment. Any repaired or replacement part furnished hereunder shall be warranted for the remainder of the warranty period of the Equipment in which it is installed. Where such failure cannot be corrected by Seller’s reasonable efforts, the parties will negotiate an equitable adjustment in price. Labor to perform warranty service will be provided at no charge during the warranty period only for the Equipment covered under Paragraph B.3 and B.4. To be eligible for no-charge labor, service must be performed at Seller’s factory, by an Authorized Service Center (ASC) or other Servicer approved for these purposes either at its place of business during normal business hours, for mobile or personal equipment, or at the Buyer’s location, for fixed location equipment. Service on fixed location equipment more than thirty (30) miles from the Service Center or other approved Servicer’s place of business will include a charge for transportation. D. Seller’s obligations under Paragraph C shall not apply to any Equipment, or part thereof, which (i) has been modified or otherwise altered other than pursuant to Seller’s written instructions or written approval or, (ii) is normally consumed in operation or, (iii) has a normal life inherently shorter than the warranty periods specified in Paragraph B, or (iv) is not properly stored, installed, used, maintained or repaired, or, (v) has been subjected to any other kind of misuse or detrimental exposure, or has been involved in an accident. E. The preceding paragraphs set forth the exclusive remedies for claims based upon defects in or nonconformity of the Equipment, whether the claim is in contract, warranty, tort (including negligence), strict liability or otherwise, and however instituted. Upon the expiration of the warranty period, all such liability shall terminate. The foregoing warranties are exclusive and in lieu of all other warranties, whether oral, written, expressed, implied or statutory. NO IMPLIED OR STATUTORY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE SHALL APPLY. IN NO EVENT SHALL THE SELLER BE LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, INDIRECT OR EXEMPLARY DAMAGES. This warranty applies only within the United States.
