INTRODUCTION

Welcome to the world of Citizens Band radio communications. Your
Uniden radio is an advanced mobile radio designed for use in the
Citizens Band (CB) Radio Service. It will operate on any of the 40 AM
frequencies authorized by the Federal Communications Commission
(FCC). Your Radio features a superheterodyne circuit with PHASE
LOCKED LOOP techniques to assure precise frequency control.

Safety Notice

The antenna used for this radio must be properly installed and
maintained and must provide a separation distance of at least 34 cm
(13.4 Inches) from all persons and must not be collocated or operated
in conjunction with any other antenna or transmitter. Never transmit if

any person is closer than the specied distance to the antenna.

Note that Uniden does not specify or supply any antenna with
this transceiver. While a 0 dBi gain antenna is normal for a typical
installation, the above limit applies to any antenna with up to 3 dBi gain.

This device complies with Industry Canada license-exempt RSS
standard(s). Operation is subject to the following two conditions: (1) this
device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation
of the device.

CB license requirement

U.S. users no longer need to apply for a license to use a CB radio.
However, CB radio is still considered a “license by rule” service. This
means that, while the FCC permits CB station operation without station

identication, station operators are still required to comply with the

2

Communications Act and with the rules of CB Radio Service. (For more
information on U.S. radio rules, visit the FCC website at www.fcc.gov.)

INSTALLATION

Connect the microphone

Align the microphone connector with the jack on the front of the radio.

Push the connector in rmly and secure it with the locking screw.

Connect the power

You can connect the radio to any standard 12 volt DC power source,
with either a positive or negative ground. If you don’t know whether
your power supply uses a positive or negative ground, consult the
manual for your power supply or contact the manufacturer.

WARNING! DO NOT connect this equipment to a power supply if you
are not absolutely certain of the grounding type!

1) Make sure your power supply is turned off.

2) For power supplies with a NEGATIVE ground, connect the RED
lead on the radio to the power supply’s POSITIVE (+) pole, and
connect the BLACK lead to the power supply’s NEGATIVE (–) pole
or to a neutral ground such as the chassis.
Turn on your power supply.

3) Turn the radio’s Volume knob clockwise to power on the radio.

Installing the mounting bracket

When choosing the location for the radio’s mounting bracket, keep the
following things in mind:

5

► Pick a location that does not block your view, interfere with your

vehicle’s controls, or hinder your driving.

► Make sure the radio and microphone are not in front of an airbag.

► Pick a solid surface that can support the bracket and radio weight.

► Make sure there’s enough room. (You may want to put the radio in

the bracket when you’re choosing where to install the bracket.)

Once you choose the location, use the included, self-tapping screws
to attach the mounting bracket and the microphone bracket to your
vehicle (you don’t have to drill holes). Slide the radio into the bracket
and use the included knobs to hold it at the preferred angle.

Connecting an external antenna

WARNING! The antenna used for this radio must be installed at least
8 inches (20 cm) away from all persons. The antenna must not be
collocated or used with any other antenna or transmitter.

CAUTION: Never operate your radio with no antenna or with a
damaged antenna cable. This can damage the radio.

You will need to purchase an antenna to operate the radio. There are
two basic types of mobile CB antennas–full-length whips and loaded
whips–with a wide variety of mounts to suit different vehicle locations.

► Choose an antenna that matches the specications of this radio.

► Follow the manufacturer’s installation instructions carefully.

► Tune your antenna using a Standing-Wave Ratio (SWR) meter: set

the radio to channel 20, and adjust the antenna until the SWR is as
close as 1:1 as possible.

Connecting external speakers

Your radio supports two external speakers for remote monitoring and
public address features. External speakers are sold separately.

To prevent feedback, direct all speakers away from the microphone.

needs. Consult the specications in the back of this manual for detailed
