Safety and General Information
Important Information on Safe and Efficient Operation
Read This Information Before Using Your Radio.
The information provided in this document supersedes the general safety information in user
guides published prior to December 1, 2002.
Transmit and Receive Procedure
Your two-way radio contains a transmitter and a receiver. To control your exposure and ensure
compliance with the general population/uncontrolled environment exposure limits, always adhere
to the following procedure:
• Transmit no more than 50% of the time.
• To receive calls, release the PTT button.
• To transmit (talk), press the Push to Talk (PTT) button.
Transmitting 50% of the time, or less, is important because the radio generates measurable RF
energy exposure only when transmitting (in terms of measuring standards compliance).
Exposure to Radio Frequency Energy
Your Motorola two-way radio complies with the following RF energy exposure standards and
guidelines:
• United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2
sub-part J.
• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers
(IEEE) C95. 1-1992.
• Institute of Electrical and Electronics Engineers (IEEE) C95. 1-1999 Edition.
• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998.
• Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radiofrequency
Electromagnetic Fields in the Frequency Range from 3 KHz to 300 GHz, 1999.
•Australian Communications Authority Radio communications (Electromagnetic
Radiation—Human Exposure) Standard, 2003.
• ANATEL ANNEX to Resolution No. 303 of July 2, 2002
• ANATEL ANNEX to Resolution No. 533 of September 10, 2009.
To ensure optimal radio performance and make sure human exposure to radio frequency
electromagnetic energy is within the guidelines set forth in the above standards, always adhere to
the following procedures.
Portable Radio Operation and EME Exposure
Antenna Care
Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications,
or attachments could damage the radio and may violate FCC regulations.
Do NOT hold the antenna when the radio is “IN USE.” Holding the antenna affects its effective
range.
Body-Worn Operation
To maintain compliances with FCC/Health Canada RF exposure guidelines if you wear a
radio on your body when transmitting always place the radio in a Motorola-supplied or
approved clip holder, holster, case or body harness for this product. Use of
non-Motorola-approved accessories may exceed FCC/Health Canada RF exposure
guidelines.
If you do not use one of the Motorola-supplied or approved body-worn accessories and
are not using the radio held in the normal use position, ensure the radio and its antenna are
at least 1 inch (2.5 cm) from your body when transmitting.
Data Operation
If applicable, when using any data feature of the radio with or without an accessory cable,
position the radio and its antenna at least one inch (2.5 cm) from the body.
Electromagnetic Interference/Compatibility
Note: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if
inadequately shielded, designed or otherwise configured for electromagnetic compatibility.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference;
2. This device must accept any interference received, including interference that may
cause undesired operation.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in
any facility where posted notices instruct you to do so. Hospitals or health care facilities
may be using equipment that is sensitive to external RF energy.
Aircraft
When instructed to do so, turn off your radio when onboard an aircraft. Any use of a radio
must be in accordance with applicable regulations per airline crew instructions.
Medical Devices – Pacemakers
The Advanced Medical Technology Association recommends that a minimum separation
of 6 inches (15 cm) be maintained between a handheld wireless radio and a pacemaker.
These recommendations are consistent with the independent research by and
recommendations of the U.S. Food and Drug Administration.
People with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 cm) from their pacemaker when the
radio is turned ON.
• Not carry the radio in the breast pocket.
• Use the ear opposite the pacemaker to minimize the potential for interference.
• Turn the radio OFF immediately if there is any reason to suspect that interference is
taking place.
Medical Devices – Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such
interference, you may want to consult your hearing aid manufacturer to discuss
alternatives.
Medical Devices – Other
If you use any other personal medical device, consult the manufacturer of your device to
determine if it is adequately shielded from RF energy. Your physician may be able to
assist you in obtaining this information.
Safety and General Use While Driving
Check the laws and regulations regarding the use of radios in the area where you drive,
and always obey them. If you do use your radio while driving, please:
• Give full attention to driving and to the road.
• Use hands-free operation, if available.
• Pull off the road and park before making or answering a call if driving conditions so
require.
The use of a two-way radio while engaged in activities requiring concentration may cause
distraction or otherwise impair your ability to safely participate in such activities. Always
use technology safely.
Do not place a portable radio in the area over an air bag or in the air bag deployment area.
Air bags inflate with great force. If a portable radio is placed in the air bag deployment
area and the air bag inflates, the radio may be propelled with great force and cause
serious injury to occupants of the vehicle.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive atmosphere. Only
radio types that are especially qualified should be used in such areas as “Intrinsically
Safe.” Do not remove, install or charge batteries in such areas. Sparks in a potentially
explosive atmosphere can cause an explosion or fire resulting in bodily injury or even
death.
Note: The areas with potentially explosive atmospheres referred to above include fueling
areas such as below decks on boats, fuel or chemical transfer or storage facilities, areas
where the air contains chemicals or particles (such as grain, dust or metal powders) and
any other area where you would normally be advised to turn off your vehicle engine. Areas
with potentially explosive atmospheres are often—but not always—posted.
Blasting Caps and Areas
To avoid possible interference with blasting operations, turn off your radio when you are
near electrical blasting caps, in a blasting area, or in areas posted “Turn off two-way
radios.” Obey all signs and instructions.
Operational Cautions
Antennas
Do not use any portable radio that has a damaged antenna. If a damaged antenna
comes into contact with your skin, a minor burn can result.
Batteries
All batteries can cause property damage and/or bodily injury such as burns if a conductive
material—like jewelry, keys or beaded chains—touch exposed terminals. The conductive
material may complete an electrical circuit (short circuit) and become quite hot. Exercise
care in handling any charged battery, particularly when placing it inside a pocket, purse or
other container with metal objects.
Exercise care when removing NiMH or AA batteries. Do not use sharp or conductive tools
to remove either of these batteries.

Scanning Channels
Use scan to search the 22 channels for transmissions from unknown parties, to find
someone in your group who has accidentally changed channels, or to quickly find unused
channels for your own use.
There is a priority feature and 2 modes of scanning (basic and advanced) to make your
search more effective. The basic scan mode uses the channel and code combinations for
each of the 22 channels as you have set them. The “Advanced Scan” mode will scan all
channels for any and all codes, detect any code in use, and use that code value
temporarily for that channel.
Priority is given to the “home channel,” that is, the channel (and Interference Eliminator
Code) your radio is set to when you start the scan. This means the initial channel (and
code setting) is scanned more often than the other 21 channels, and your radio will
respond quickly to any activity occurring on the home channel as a priority.
To start Scanning:
1. Briefly press the key. The scan will appear in the display, and the radio will
begin to scroll through the channel and code combinations.
2. When the radio detects channel activity matching the channel and code combination, it
stops scrolling and you can hear the transmission.
3. To respond and talk to the person transmitting, press within five seconds after the
end of the transmission.
4. The radio will resume scrolling through the channels five seconds after the end of any
received activity.
5. To stop scanning, briefly press the key.
To start Advanced Scanning:
1. Set the Interference Eliminator Code to “0”.
2. Briefly press the key. The scan will appear in the display, and the radio will
begin to scroll through the channels. No Interference Eliminator Codes will filter what is
heard.
3. When the radio detects channel activity with ANY code (or NO code), it stops scrolling
and you can hear the transmission. Any Interference Eliminator Code that may be in use
by that party will be detected and displayed.
4. To respond and talk to the person transmitting, press within five seconds of the
end of the transmission. The radio will transmit using the newly detected Interference
Eliminator Code.

Weather Receiver
This radio can tune in to broadcasts by the United States National Oceanic and
Atmospheric Administration (NOAA) Weather Radio.
You can listen to a weather channel (see “Weather Channels and
Frequencies” table for details) or set the radio to alert you to emergency weather
broadcasts that interrupt routine broadcasts. When you listen to a weather channel, you
cannot use the radio in scan mode or for two-way communications.
NOAA has transmitters located throughout the United States. These transmitters
broadcast watches, forecasts, and other information 24 hours a day.
Note: NOAA weather radio stations are assigned to cover specific areas and service may
be limited. Please check with your local weather office for frequency and details, or visit
www.weather.gov/nwr in the US to view the appropriate transmitter for your area.
