The RCI-5054DX is easy to install. All necessary parts ( less the antenna
and cable ) have been included to facilitate installation.
and cable ) have been included to facilitate installation.
Transceiver Mounting
Choose a suitable location for the transceiver that will allow easy access to
the front panel as well as proper air circulation to the back of the unit. If you
are installing the unit in a vehicle , attach the mounting bracket first, then
attach the transceiver to the mounting bracket using the hardware provided.
Before making any electrical connection, ensure that the transceiver is
turned off and the vehicle's battery is disconnected.

Power Connection
The transceiver operates off of any regulated 13.8 VDC negative or positive
ground source.
ground source.
If an AC power supply is used with your radio, it must be regulated and rated
for at least 7 Amps continuous for the RCI-5054DX. Low voltage while under
load will reduce receiver gain and transmitter output.

NOTE
The condition of a vehicle's electrical system can affect the operation of
your RCI-5054DX . A low battery , worn generator/alternator , or poor
voltage regulator will impair performance of the unit as well as the vehicle.
(High noise generation or low voltage delivery can result from these
conditions.)

CAUTION
Voltage above 15 VDC will damage the unit. Be sure to check the
source voltage before connecting the power cord.

1. FREQUENCY SELECTOR : Used to select the desired transmit and
receive frequency, the FREQUENCY SELECTOR allows continuous
tuning over the entire range of the transceiver.

2. RF POWER CONTROL : This control adjust the RF power output level
you want in AM/FM/SSB transmission.
3. MIC GAIN CONTROL : This feature adjust the microphone gain in the
transmit and PA modes, changing the audio level of the microphone for
maximum performance and clarity.

4. ON/OFF VOLUME CONTROL : Turn clockwise to apply power to the
radio and to set the desired listening level.
5. SQUELCH CONTROL : This control is used to control or eliminate
receiver background noise in the absence of an incoming signal. For
maximum receiver sensitivity, it is necessary that the control be adjusted
only the point where the receiver background noise is eliminated. Turn
fully counterclockwise and then slowly clockwise until the receiver noise
