OPERATION

Before you start using your CB, you should know how to use it effectively and courteously. “CB Operation Tips” contains information that will help you use and enjoy your CB.

RECEIVING TRANSMISSIONS AND ADJUSTING SQUELCH

Caution: Do not attempt to use your CB without first connecting an anten- na to it.

1.Turn SQUELCH fully counter- clockwise.

2.To turn on the CB, turn VOLUME clockwise until you hear it click and you hear a hissing sound. The CB displays a channel num- ber.

Note: If the CB picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to decrease the CB’s sensitivity to these signals. If you want to listen to a weak or distant station, turn SQUELCH counterclockwise.

4.Adjust VOLUME to a comfortable listening level.

5.Press DOWN to select lower channels or UP to select higher channels. The channel number appears on the display.

Important! Channel 9 is reserved for motorist assistance and for reporting emergency information about accidents, hazardous road conditions, and so on. Always give emergency messages priority on Channel 9.
