Installation

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, 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:

• 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 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.

CAUTION: Make sure the SWR is less than 2:1 before using the radio. An SWR higher than 2:1 can damage the transmitter.

Maintenance

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.
