9. Fault Finding
Problem
Possible Causes
Solution
Equipment display not lit
-Supply voltage missing on PIN24
-Radio not switched on
-Equipment fuse blown
-Radio signal not recognised
-Check the voltage on PIN24 e.g.
Test function of the 12V socket with
charger cable
-Switch on radio
-Replace plug in fuse on the circuit
board
-Connect the ignition plus signal in
addition
Equipment display does not shut
down
-Switch off delay not working (+-
40min.)
-Noise in audio signal
-Switch off radio
-Switch off audio source
-Switch off ignition (PIN22)
-Increase threshold switching value
No audio output through
FastMute
Sonic XL
-Volume too low
-Threshold switching value too high
-Missing audio signal
-Incorrect connector cable
-Increase volume of the audio source
-Reduce threshold trigger value (Turn
the potentiometer a little to the left)
-Check the audio signal source with
headphones
-Use Stereo-connector cable (3 cores)
Switchover and mute signal
happens without an input audio
signal
-Threshold trigger value too low
-Noisy audio signal
- Increase threshold trigger value
(Turn the potentiometer a little to the
right)
-Check battery of audio source
