D) TROUBLE SHOOTING
1) YOUR CB RADIO WILL NOT TRANSMIT OR YOUR TRANSMISSION
IS OF POOR QUALITY
- Check that the antenna is correctly connected and that the SWR is properly adjusted.
- Check that the microphone is properly plugged in.
- Check that the programmed configuration is the correct one (see table page 49).
2) YOUR CB RADIO WILL NOT RECEIVE OR RECEPTION IS POOR
- Check that the squelch level is properly adjusted.
- Check that the volume is set to a comfortable listening level.
- Check that the programmed configuration is the correct one (see table page 49).
- Check that the microphone is properly plugged in.
- Check that the antenna is correctly connected and that the SWR is properly adjusted.
- Check that you are using the same modulation mode as your correspondent.
