Symptom Solution
No power
Make sure the power supply is securely plugged into a standard wall outlet and the
cord is plugged into the power connector on the CB module.
Make sure the CB module is turned on using the front panel power button or the
remote control power button.
CB is not responding to the
remote control
Make sure to point the remote control directly at the remote control sensor on the
CB, with no obstacles in between them.
You may be too far from CB. Try moving closer.
Make sure that the remote control batteries are installed in the correct direction (+
and –).
The batteries may be depleted. Try replacing them with new ones.
Verify CB is operating correctly by pressing buttons on the front panel of CB.
No picture
Make sure that the antenna in cable is correctly connected to the CB.
Make sure that the video out cable is correctly connected to the CB and TV.
Make sure that the CB and TV are turned on.
Make sure that the TV is correctly set to the selected CB video output channel.
Refer to the TV owner’s manual for further information.
Check the antenna and the antenna cable. There may be damage or interference
sources.
Picture is blocky or not clear
Check the antenna and the antenna cable. There may be damage or interference
sources.
Reposition the antenna to improve signal strength. Signal strength can also be
affected by rain or snow. In the USA, the website www.antennaweb.org
can
provide help in determining the best antenna orientation.
No sound
Make sure that the audio cables are correctly connected between the CB audio
outputs and the TV audio inputs.
Make sure that CB and TV are turned on.
Make sure the CB and TV volume settings are at a reasonable level.
Make sure that the MUTE function is not activated on the CB or TV.
Make sure the TV is correctly set to the selected C B audio output channel.
When TV has only one audio input jack, use a standard audio cable (white) to
connect the audio output jack (white) on the C B to the audio input jack on the TV.
The red audio cable and the CB red audio output jack are not needed.
