© TTI and Geonautics 5 Law Enforcement ONLY INTRODUCTION Tactical Technologies Inc. Joey J1W (Model numbers CTR-751WT, CTR-752WT, CTR-753WT, CTR-754WT, CTR-754X2WT) is a 1 channel, VHF-FM synthesized voice transmitter combined with a state of the art solid-state digital recorder, specifically designed for law enforcement use. The concise product description of the J1W would be TRANSCORDER. The unit utilizes an external antenna for the transmitter and a single microphone for both the transmitter and recorder operations. The J1W can be equipped with an optional scrambler for added transmitter security. The Joey1W, whilst utilizing an onboard hardware compander, derives unprecedented audio quality from its ability to capture sounds at user definable settings. The J1W uses flash memory as onboard storage, is fully configurable and allows the user to trade off between quality and recording time to suit their application. Figure 1, The Joey1W Transcorder

© TTI and Geonautics 8 Law Enforcement ONLY 1.3 Using the J1W Transcorder The J1W is designed to be used,  operationally in a stand alone configuration, or  in conjunction with its USB cable and a personal computer for configuration, downloading and replay of stored audio, or  connected to a personal computer, TTI Citation Receiver, or TTI PTX-100 for Transmitter Only Frequency Programming. Before using the J1R in an operational environment, it should first be run in PC Mode and the recorder configured using the accompanying Joey software. The Transmitter operating frequency must be programmed separately. NOTE: Transmitter must be switched OFF while operating in PC Mode. 1.4 PC Mode – Recorder Operation Install the Joey software and USB device drivers. Using the USB cable supplied, connect the J1R to the computer and configure the unit to the desired operational parameters by running the Joey software. Make sure the Transmitter ON/OFF switch is in the OFF position. To connect the USB cable to the Joey1W, align the arrow and yellow dot on the USB Cable 6 pin connector with the yellow dot 6 pin connector of the J1W unit. If you attempt to install the cable upside down, you will damage the Joey1W.
© TTI and Geonautics 9 Law Enforcement ONLY Make sure that the connector makes contact head on with the J1W, ensuring no twist in the connection which may result in connector damage. Removal of cables also requires the connectors to come off without much twist, so that damage does not occur to the unit. When using the USB cable, the Joey1W’s recorder draws power directly from the computer through the cable. After you are finished configuring the Joey1W, disconnect the recorder from the USB cable. The recorder will remember it’s configuration parameters and will operate according to those parameters the next time power is applied. 1.5 Stand Alone Mode Once the recorder is configured using the Joey program and transmitter frequency has been programmed using a Citation Receiver, Personal Computer, or PTX-100 programmer. The transmitter and recorder will remember and use the current configuration each and every time power is applied to the unit. 1.5.1 Making the Connections For an operation, you must decide how you want to configure your J1R. 1. No matter what, you must connect the antenna. 2. External tethered or internal microphone? 3. Is there a need for the optional, tethered remote ON/OFF switch? See the diagram below for connector placement on the J1W.

Antenna Connector D: MASTER On/Off Switch E: 6 Pin connector for recorder programming, or external remote on/off switch. Antenna Connect the external antenna to the J1W by inserting the male end of the SMC type antenna connector on the device to the female connector end on the wire antenna. Twist the connector clockwise to tighten, HAND TIGHT ONLY! Microphone
© TTI and Geonautics 11 Law Enforcement ONLY Determine which of the two microphone configurations are best for your application: the long tethered remote microphone or the internal microphone. If you choose the internal microphone, you do not need to do anything. If you choose the external microphone, connect the external microphone by inserting the plug male end of the mini connector on the microphone cable into the female jack found on the J1W. Push the connectors firmly together. Twist the plug clockwise slightly to lock the connector in place. HAND TIGHT ONLY! Switching between the internal and external microphones is automatic and accomplished when the external microphone plug is inserted into (or removed from) the microphone jack on the J1W. Power IMPORTANT: Before applying power to the J1W ensure that: a) The Transmitter On/Off Switch is OFF, or b) An antenna is connected to the J1W. Never apply power to the J1W without an antenna connected. The J1W is powered by two 9 volt batteries which will operate both the transmitter and the recorder for up to 3 hours. 1.5.2 Microphone and Antenna Placement As a general rule the external microphone should be as close as possible to mouth level. Sound waves travel in straight lines and the placement should reduce obvious obstructions. If a microphone is to be placed behind a surface, which is not porous, a small pin hole should be placed in the surface opposite the microphones diaphragm.
© TTI and Geonautics 12 Law Enforcement ONLY Ensure that any material will not rub against the surface of the microphone. For maximum efficiency, the J1W antenna should be kept vertical whenever possible. Placing the antenna on a metal object may result in quite poor performance of the J1W’s transmitter. The antenna should not be wrapped around the J1W, nor should it be coiled or bunched in a ball. The antenna used for this transmitter must not be collocated or operating in conjunction with any other antenna or transmitter. The antenna must be installed to provide a separation distance of at least 20 cm from all persons. 1.5.3 Operational Mode When power is applied to the J1W via the master power switch, the unit will wait for approximately three seconds, and then start to record using its current configuration. Note: The exception to this is if the unit has been previously configured for timer mode. (See Error! Reference source not found. Error! Reference source not found.) Once the unit is recording, the transmitter will come on instantly when the Transmitter Power Switch is turned ON (towards the red dot). Removing power stops the recording and the RF transmissions. Subsequent recordings and resumption of transmissions may be made by re-applying power to the recorder. This is repeatable up until the unit becomes full and cannot record any more audio. The transmitter will still operate, even if the recorder is full.. When the operation is completed or the recorder becomes full, it should be downloaded using the Joey program. The recorder does not require power to retain its recordings and downloading can happen at any time subsequent to a recording being made.
© TTI and Geonautics 13 Law Enforcement ONLY Noteworthy Operational Considerations Before ANY use of the Joey1W: 1. Verify the TRANSMITTER is functioning correctly by checking its transmission with a good quality receiver programmed to the correct frequency. 2. Verify the RECORDER portion by operating the J1W in PC Mode and making a test recording. 3. ALWAYS use a fully charged battery at the start of any operation. 4. PRACTICE with this piece of equipment prior to official use. 1.6 Timer Mode When configured to timer mode, the J1W’s recorder will sleep until the next preset start time has been reached. After all timers have expired, the J1W’s recorder remains in sleep mode until a power reset returns it to normal operation. If all start times have expired prior to power being applied, the J1W’s recorder operates as if no timers had been set. 1.7 Recording Quality The Joey1W’s audio front end and data storage algorithms are designed to provide the user with a range of quality options ranging from direct storage of the 8 bit samples (Linear Pulse Code Modulation, LPCM) to Adaptive Differential Pulse Code Modulation (ADPCM) for the 4 bit modes. Sampling Speed (kHz) Typical Bandwidth (Hz) 8 3200 11 4700 Table 2, Typical Joey1W Recorder Audio Bandwidths 1.8 Recording Times

Battery Cell Type Operation mAHrs Timer Correction Hrs 1 x 9v 9 VDC Alkaline Recorder only 565 4 hrs per day 60 1 x 9v 9 VDC Alkaline Transmit and Record 565 0.5 hrs per day 3 Table 4, Battery Life When the J1W recorder is used in timer mode), the expected operating hours must be reduced. 1.10 Concealment and Tactical Issues Concealment and tactical issues surrounding the use of the Joey1W are beyond the scope of this guide. 1.10.1 Range of the J1W Transmitter It is impossible to state absolutes about how far an RF transmitter like the J1W will transmit. Many variables affect the range of a device including buildings, trees, weather, construction materials, installation, etc. All things being perfect (meaning transmissions are outdoors over flat terrain with no obstructions), a Joey1W should be able to easily transmit over a mile. You should expect less distance than that however, in a real world operation.
© TTI and Geonautics 16 Law Enforcement ONLY One of the most important variables, and one that the operator can actually control, is the placement of the receiver and the receiving antenna. A good rule to follow is the higher the antenna placement, the better chance you have of quality reception. This alone will increase your operating range. Just having the J1W in an ideal location is not enough.
