TRANSCEIVER PREPARATION
Installation/Tools Needed
• Electric drill with 6mm bit or above
• Cross head screwdriver
• Hex socket sleeve (used for mounting 5mm × 16mm self-tapping screw)
When installing your transceiver, be sure to select a safe, convenient location. If you’re
installing inside your vehicle, choose a location that minimizes danger to your passengers
and yourself while the vehicle is in motion. Consider installing the unit so that knees or legs
will not strike the unit during vehicle operation. Try to pick a well ventilated location that is
shielded from direct sunlight for your installation location.
Install the mounting bracket in the vehicle using the supplied self-tapping screws (4), flat
washers (4), and spring washers (4). Position the bracket so that the 3 long screw hole
positions on the side of the mounting bracket are towards the rear of the bracket. (Figure 1)
Use the 3 screw positions on the side of the mounting bracket to determine the appropriate
angle of the transceiver. (Figure 2) Position the transceiver, then insert and tighten the
supplied hexagon SEMS screws (4) and flat washers (4). (Figure 3) Double check that all
hardware is securely fastened to ensure that vehicle vibration will not loosen the bracket
or transceiver.

DC Power Cable Connection
Mobile Operation
Your vehicle battery must have a nominal rating of 12V. Never connect the transceiver to
a 24V battery. Be sure to use a 12V vehicle battery that has sucient current capacity. If
the current to the transceiver Is insucient, the display may darken during transmission, or
transmit output power may drop excessively.
1. Route the DC power cable supplied with the transceiver directly to the vehicle’s battery
terminals using the shortest path from the transceiver. If using a noise filter, it should
be installed with an insulator to prevent it from touching metal on the vehicle. We
recommend you do not use the power outlet/cigarette lighter socket as some power
outlets have an unacceptable voltage drop. The entire length of the cable must be
dressed so it is isolated from heat, moisture and the engine secondary (high voltage)
ignition system/cables.
2. After the cable Is In place, wrap heat-resistant tape around all fuse holders to protect it
from moisture and tie down the full run of cable.
3. To prevent the risk of short circuiting, disconnect other wiring from the negative (-)
battery terminal before connecting the transceiver.

4. Confirm the correct polarity of the connections, then attach the power cable to the
battery terminals; red connects to the positive (+) terminal and black connects to the
negative (-) terminal. Use the full length of the supplied cable without cutting o excess
even If the cable is longer than required. In particular, never remove the fuse holders
from the cable. (Figure 4)
5. Reconnect any wiring removed from the negative terminal.
6. Connect the DC power cable to the transceiver’s power supply connector. Press the
connectors firmly together until the locking tab connectors firmly together until the
locking tab clicks. (Figure 5)

Microphone Jack
For voice communications, connect a 600 Ω microphone equipped with an 8-pin modular
plug into the modular socket on the front of the main unit. Press firmly on the plug until the
locking tab clicks. (Figure 8)

Microphone Hanger
Attach the supplied microphone hanger using included screws in an easy to access
location that will not interfere with vehicle operation. (Figure 9)

Operational Status Indicators
Your radio indicates its operational status through the following:
• Display Icons
• Call Icons
• Sent Item Icons
• LED Indicator
• Audio Tones
Display Icons
The LCD display shows radio status, text entries, and menu entries. The following icons
will appear on the radio’s display. (see chart)
Audio Tones
Alert tones provide you with audible indications of the radio’s status or the radio’s
response to data received.
Continuous Tone - A monotone sound.
Sounds continuously until termination.
Periodic Tone - Sounds periodically depending on the duration set by the radio.
Repetitive Tone - A single tone that repeats itself until it is terminated by the user.
Momentary Tone - Sounds only once for a short period of time defined by the radio.
Antenna Connection
Before operating the radio, install an ecient, well-tuned antenna. The success of your radio
installation will depend largely on the type and installation of your antenna. The transceiver
will provide excellent results if the antenna system and radio installation are handled
properly. (Figure 6)
Use a 50 Ω impedance antenna and low-loss coaxial feed line that has a characteristic
impedance of 50 Ω to match the transceiver input impedance. Coupling the antenna to the
transceiver via feed lines having an impedance other than 50 Ω reduces the eciency of
the antenna system and can cause interference to nearby broadcast television and radio
receivers, and other electronic equipment.
Accessory Connections
External Speaker
If you plan to use an external speaker, choose a speaker with an impedance of 8 Ω. The
external speaker jack accepts a 1/8” (3.5 mm) mono (2-conductor) plug. (Figure 7)
Caution:
• Transmitting without first connecting an antenna or other matched load may
damage the transceiver. Always connect the antenna to the transceiver before
transmitting.
• All fixed stations should be equipped with a lightning arrester to reduce the risk of
fire, electric shock, and transceiver damage.
Making and Receiving Calls
1. Hold the microphone about 2” from your mouth when speaking and press the [PTT]
(push to talk) button. (Figure 10) The red LED lights during call.
2. Release [PTT] to return to the receive/listen (RX) mode. To receive your radio must be
switched to the proper channel and set with matching signaling or Color Code and
Group ID if used in digital mode.

PTT Button
(Push to talk)
Note on PTT: If the Talk Permit Tone is enabled, wait
until the short alert tone ends before talking.
During a call, if the Channel Free Indication feature
is enabled on your radio (programmed by your RCA
Communications Systems Dealer), you will hear a short
alert tone the moment the target radio (the radio that is
receiving your call) releases the PTT button, indicating the
channel is free for you to respond. You will also hear the
Channel Free Indication tone if your call is interrupted, for
example, when the radio receives an Emergency Call.
