F) 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 bargraph is set on maximum.
- Check that the MIC GAIN bargraph is set on maximum.
2) YOUR CB RADIO WILL NOT RECEIVE OR RECEPTION IS
POOR
- Check that the RF GAIN bargraph is set on maximum.
- Check that the squelch level is properly adjusted.
- Check that the volume is set to a comfortable listening level.
- Check that the antenna is correctly connected and that the SWR
is properly adjusted.
3) YOUR CB WILL NOT LIGHT UP
- Check the power supply.
- Check the connection wiring.
- Check the fuse.
G) 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 and announce your message “At-
tention 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 commu-
nication with someone, it is common practice to choose another
available channel so as not to block the calling channel.
