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 RF POWER switch ( 1 ) is set on maximum.
- Check that the CLARIFIER, FINE/COARSE ( 4 ) switches are set on central position.
- Check that the programmed configuration is the correct one (see p. 50) .
2) YOUR CB RADIO WILL NOT RECEIVE OR RECEPTION IS POOR
- Check that the RFGAIN (
3
) is set on maximum.
- Check that the squelch level is properly adjusted.
- Check that the programmed configuration is the correct one (see p. 50) .
- 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.
- Check that the CLARIFIER, FINE/COARSE (
4
) switches are set on central position.
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).
