SAFETY AND GENERAL INFORMATION
This radio is restricted to occupational use only
to satisfy FCC RF energy exposure requirements.
Before using this product, read the operating
instructions.
•Do not transmit using high output power
for extended periods as the transceiver may
overheat.
•Turn radio off prior to entering any area with a
potentially explosive atmosphere, such as gas,
petroleum, chemicals, blasting caps, etc.
•Do not attempt to congure your transceiver
while driving. Be aware of local laws regarding
the use of headsets while driving.
•This equipment is to be serviced only by
authorized RCA Communications Systems
technicians. Any service performed by
unauthorized technicians will void the warranty.
•Turn radio off when near electrical blasting
caps to avoid possible interference with blasting
operations. Obey posted signs such as those in
hospitals or blasting areas advising people to
turn off all two-way radios.
•Do not place radio equipment over an air bag or
in an air bag’s deployment area, as an inated
air bag could propel the equipment and cause
serious injury.
•Do not place the radio close to a heat source
or expose the radio to direct sunlight for a
prolonged time.
•Do not place the transceiver in an excessively
dusty, humid or wet area, or on an unstable
surface.
•If smoke or an abnormal odor is detected
coming from the transceiver, turn OFF the
transceiver immediately and contact your RCA
dealer.

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), at 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

Installation/Tools Needed
•Electric drill with 6mm bit or above
•Cross head screwdriver
•Hex socket sleeve (used for mounting 5mm ×

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

(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 sufcient current capacity. If the current to the
transceiver Is insufcient, 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 lter, 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. Conrm 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 off 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
rmly together until the locking tab connectors
rmly together until the locking tab clicks.
(Figure 5)
Fixed Station Operation
In order to use this transceiver in a xed station
operation, you will need a separate 13.8V DC
power supply (not included). The recommended
current capacity of your power supply is 14A or
more.
1. Connect the DC power cable to the regulated
DC power supply and ensure that the polarities
are correct (Red: positive, Black: negative).
• Do not directly connect the transceiver to
an AC outlet.
• Use the supplied DC power cable to
connect the transceiver to a regulated
power supply. Do not substitute a cable
with smaller gauge wires. (Figure 6)
Copyright © 2015 RCA Communications Systems
11BRM300DTM Professional Digital Two-Way Mobile Radio Instruction Manual
• Do not plug the DC power supply into an AC
outlet until you make all connections.
Replacing Fuses
If a fuse blows, most times it indicates a problem.
Check the power source and the power cables
to determine the cause and then correct the
problem. Once the problem is resolved, replace
the fuse. (See Figure 7.) If newly installed fuses
continue to blow, disconnect the power cable and
contact your authorized RCA Dealer for assistance.

DC Power Cable 20A
2. Connect the transceiver’s DC power connector
to the connector on the DC power cable. Press
the connectors rmly together until the locking
tab clicks. (See Figure 5)
NOTE:
• For your transceiver to perform properly, we
recommend using a power supply with an
output of more than 23A/25% duty cycle.
• Before connecting the DC power supply to the
transceiver. be sure to switch the transceiver
and the DC power supply OFF.

CAUTION
Only use fuses of the specied type and
rating; otherwise the transceiver can be
damaged.
Note:
If you use the transceiver for a long period when
the vehicle battery is not fully charged or when the
engine is OFF, the battery may become discharged
and may not have sufcient reserves to start the
vehicle. Avoid using the transceiver under these
conditions.
Antenna Connection
Before operating the radio, install an efcient,
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 8)
Use a 50 Ωimpedance antenna and low-loss
coaxial feed line that has a characteristic impedance
of 50 Ωto match the transceiver input impedance.
Coupling the antenna to the transceiver via feed
lines having an impedance other than 50 Ωreduces
the efciency of the antenna system and can cause
interference to nearby broadcast television and
radio receivers, and other electronic equipment.
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 xed stations should be equipped with

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.
Select A Channel
Press [▲] or [▼] to switch between channels.
