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 confi guration is the correct one (see table page 53).
2) YOUR CB RADIO WILL NOT RECEIVE OR RECEPTION IS POOR
- Check that RF GAIN (4) is on maximum.
- Check that the squelch level is properly adjusted.
- Check that the programmed confi guration is the correct one (see table page 53).
- Check that the volume is set to a comfortable listening level.
- 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.
3) YOUR CB WILL NOT LIGHT UP
- Check the power supply.
- Check the connection wiring.
- Check the fuse.
E) HOW TO TRANSMIT OR RECEIVE A MESSAGE
Now that you have read the manual, make sure that your CB Radio is ready for use
(i.e. check that your antenna is connected).
Choose your channel (19, 27).
Choose your mode (AM/FM) which must be the same as that of your correspondent.
