Trouble shooting
Your CB radio set does not transmit at all or transmission
power is poor:
Check the standing wave ratio of your antenna as well as the cable
with regard to possible interruptions or loose contacts!
Check the micorphone for a proper connection and the connection
with regard to loose contacts!
With the push-to-talk button activated, TX should be lit and your
radio set should start transmission. By releasing the button once
again, the indicator should go out and your radio set should again
switch over to reception mode.
Your radio set does not receive any response to your
transmission or reception is poor:
Check whether the attenuator (
LOCAL
) is possibly switched on.
Check that the squelch level (
SQ
) is properly adjusted.
Check that the volume (
VOL
) is set to a comfortable listening level.
Make sure that you are using the same modulation mode (
AM
or
FM
) as your contact partner!
Your display does not light up:
Check whether your power supply unit is switched on.
Check the fuse installed in the cable!
Check the connections for proper wiring: plus pole = red and
negative pole = black! Exchange the connections if they are mixed up.
Tips on radio communication:
For enjoying an undisturbed radio communication you should
observe the following six rules of CB radio communication:
1. After switching on the radio set, always listen first whether the
set channel is free.
2. To do so, deactivate the squelch function such that you are also
able to hear weaker radio stations.
3. Start your own call only if the channel is absolutely free.
4. Transmit nothing but short calls.
5. After each call carefully listen to a station possibly answering
your call. Repeat your call only after having carefully listened.
6. After each transmission of your contact partner wait for several
seconds before answering in order to give further radio stations
the chance to participate in the radio communication (change-
over delay).
Call, emergency call and trucker channels
The usage of the following call channels is advisable:
Channel 1
(FM) as FM call channel
Channel 4
(AM) as AM call channel
Channel 9
(AM) as emergency channel and trucker channel
in Germany
Channel 19 (AM/FM) as trucker channel abroad
Deviating channels can of course be used as well.
Speech communication
When the radio contact is weak or intense interferences occur, it
is quite often difficult to understand everything perfectly, as e.g.
proper names or geographical names.
