29 GR-English.qx 6/22/99 9:14 AM Page 4 Installation Installation Note Before installing the CB radio, visually check the vehicle’s battery connection to determine which terminal, positive or negative, is earthed to the engine block (or chassis). A negatively earthed vehicle has its negative lead earthed to the chassis. Note Connecting to a fuse circuit controlled by the ignition switch prevents the unit from being left on accidentally, and also permits operating the unit without running the engine.

This calibration is critical in order to achieve optimum performance. Note 3 1 Select Push and hold microphone button. Note The reading will be slightly higher on Channels 1 and 40 com pared to Channel 20. channel 20.

With the S/RF-SWR-CAL switch in the SWR position the meter needle should ideally be as far to the left as possible. Anything over 3 is not acceptable. A slight antenna height adjustment (higher or lower) may be required. Repeat relcalibration steps.
