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.
- Check that the RF POWER value is set on maximum. (See § RF POWER page
34).
- Check that the MIC GAIN value is set on maximum. (See § MIC GAIN page
34).
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 RF GAIN level is set on maximum. (See § RF GAIN page
34).
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 (17) and announce your message «Attention
stations, transmission testing» which will allow you to check the clearness
and the power of your signal. Release the switch and wait for a reply. You
should receive a reply like, «Strong and clear».
If you use a calling channel (19) and you have established communication
with someone, it is common practice to choose another available channel
so as not to block the calling channel.
