USING THE CB AS A

BASE STATION

Although this CB is designed mainly for mobile use, you can also use it as a base station with an AC power source. For base station installation, you need the following items (all available at your local RadioShack store):

• 12-volt DC power supply (such as

Cat. No. 22-504)

Caution: Most 12-volt DC power supplies plug into a standard AC outlet to produce DC power.

Before connecting your CB to a

12-volt DC power supply, read and follow the instructions included with the power supply.

• Base station antenna (such as

Cat. No. 21-969)

• Coaxial antenna cable and connectors

Follow these steps to install the CB as a base station.

Warning: Use extreme caution when you install or remove a base station CB antenna. If the antenna starts to fall, let it go. It could contact overhead power lines. If the antenna touches the power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to do so yourself.

2. Route the antenna cable to the

CB, then connect the antenna to the ANTENNA jack on the back of the CB.

3. Connect the CB’s black power wire to the negative (–) terminal on the DC power supply.

4. Connect the CB’s red wire, with the in-line fuse, to the positive (+) terminal on the DC power supply.

5. Connect the DC power supply to a standard AC outlet.

Red wire to switched accessory terminal

Black wire to vehicle’s frame or battery (–)

1. Mount the base station antenna as described in its owner’s manual.
