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.
- With the «push-to-talk» switch activated, the display flashes. Release the
«push-to-talk» switch, then re-press it to go into transmission.
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 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.
Press the «push-to-talk» switch and announce your message «Attention
