Installation

Note

Before installing the CB radio, visually check the vehicle’s battery connection to deter- mine which terminal, positive or negative, is grounded (pos- itive is the larger of the two) to the engine block (or chas- sis). A negatively grounded vehicle has its negative lead grounded to the chassis.

Note

Connecting to an accessory fuse prevents the unit from being left on accidentally, and also per- mits operating the unit without running the engine.

Note

In positive ground vehicles the red wire goes to the chassis and the black wire is connected to the ignition switch.

4In a negative grounded vehicle, connect the red lead of the DC power cord to an accessory 12 volt fuse.

5Connect the black lead to the negative side of the vehicle. This is usually the chassis. Any con- venient location with a good electrical contact (remove paint) may be used.
