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.
The antenna used for this radio must be properly installed and maintained must provide a separation distance of at least 16.92 inches (43 cm) 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 specified 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.
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 identification, station operators are still required to comply with the 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.)

PARTS OF THE RADIO
NOTE: FCC rules reserve Channel 9 for motorist assistance and other emergency communications. Channel 9 should only be used in situations where there is immediate danger to the safety of individuals or the protection of property.
Press and hold the PTT button to transmit on the selected channel. Release the button to listen for a response.
NOTE: Make sure you have read and understood part 95 of the FCC rules and regulations before using the transmitter.
Connect the microphone
Align the microphone connector with the jack on the front of the radio. Push the connector in firmly and secure it with the locking screw.
Connect the power
You can connect the radio to any standard 12-volt DC power source, 4 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!
- Make sure your power supply is turned off.
- 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.
- 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:
- 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 16.92 inches (43 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 specifications 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.
Your Uniden dealer can help you select the antenna that is best for your needs. Consult the specifications in the back of this manual for detailed transmitter and antenna information.

- Tune the radio to the channel you want to transmit on and listen to make sure the channel is clear.
- Press and hold the PTT button.
- Hold the microphone about 2 inches away from your mouth and speak in a normal voice.
- Release the button to listen for a response.
Using the PA feature:
- Toggle the CB/PA switch to PA; this turns off the CB radio and activates the PA speaker.
- On the microphone, press and hold the PTT button.
- Hold the microphone about 2 inches away from your mouth and speak in a normal voice. Use the Volume knob to adjust the volume of the PA speaker.
- When you’re finished broadcasting, release the button and move the CB/PA switch back to CB.
Adjusting the squelch level:
- To filter out weaker signals and background noise, turn the knob clockwise to increase the squelch level.
- To decrease the squelch level so you can hear weaker radio signals, turn the knob counterclockwise.
Using the Instant Channel 9 feature:
- Press the CH9 button; the radio automatically tunes to channel 9.
- Press the CH9 button again to return to the previous channel.
NOTE: Make sure you read and understand part 95 of the FCC rules and regulations before using the transmitter.
Every six to twelve months, check to make sure that:
- The Voltage Standing Wave Ratio (VSWR) is less than 2:1.
- All electrical connections are secure and free of corrosion.
- The antenna cable shows no wear or damage.
- All mounting screws are securely fastened.
