CONNECTING VEHICLE BATTERY POWER

Follow these steps to connect the CB to vehicle battery power.

To Chassis Ground (black)

To ACC Power (red)

1.Connect the red wire (with the in- line fuse holder) on the back of the CB to a terminal in your vehicle’s fuse box that has power only when the ignition is in the ACC (acces- sory) or ON position.

2.Connect the black ground wire to a metal part of the vehicle’s frame (chassis ground).

Caution: Do not connect the black wire to a non-metallic (plastic) part, or to any part insulated from the ve- hicle’s chassis by a non-metallic part.

CONNECTING AN EXTERNAL SPEAKER

You can connect an optional external speaker to the CB. Use an 8-ohm speaker with a 1/8-inch (3.5-mm) plug. Insert the speaker’s plug into the CB’s EXT. SP. jack. Your local RadioShack store carries a wide selection of suitable speakers.

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 these items.

•a 12-volt DC power supply that can supply at least 1.5 amps

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 in- structions included with the power supply.

•base station antenna

•coaxial antenna cable and connec- tors

Note: Your local RadioShack store car- ries a wide selection of base station an- tennas, coaxial antenna cable, and connectors. In addition, you can choose from a selection of suitable base station power supplies.
