G) TROUBLE SHOOTING
1) YOUR 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.
- You are using the same modulation mode than your correspondent.
- Check that the programmed configuration is the correct one (see table
page 74) .
2) YOUR RADIO WILL NOT RECEIVE OR RECEPTION IS POOR
- Check that the squelch level is properly adjusted.
- Check that the volume (
1
) is set to a comfortable listening level.
- 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 correspond-
ent.
- Check that the programmed configuration is the correct one (see table
page 74) .
- Consult the VOLUME ACCESSORY menu page 48 .
- Check that you are not using any CTCSS/DSC code (See the §
CTCSS/DSC
page 42
3) YOUR RADIO WILL NOT LIGHT UP
- Check the power supply.
- Check the connection wiring.
- Check the fuse.
H) 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).
Press the «push-to-talk» switch ( 12 ) and announce your message «Attention
