D) BREAKDOWN GUIDE:
1) YOUR CB RADIO WILL NOT TRANSMIT OR YOUR TRANSMIS-
SION 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.
