Troubleshooting
Replay only through the front or rear speakers:
• The fader control is not adjusted correctly. Adjust the fader control.
• The speaker connection has come loose. Remove the CD tuner and/or speakers and check the connections.
In radio operation hardly any stations can be received:
• The aerial is not pulled out completely. Pull out the aerial to its full length.
• The aerial connection has come loose. Remove the CD tuner and check the connection.
• The aerial is defective. Check the connection, earthing and the aerial itself.
Interference noise during radio and CD replay:
• Interferences reach the CD tuner via the positive line. Install an additional interference suppression coil into the
positive line. If necessary, also equip the vehicle with spark-plug suppressor sockets, distributor arms etc. to
suppress interferences.
When you press a station button, you only hear hissing:
• No station has been programmed. Program the stations as described above.
Every time you switch off the CD tuner, the station programming gets lost:
• The continuous positive line is not connected, or has come loose. Connect or check the continuous positive line
as explained in the instructions or check whether the cable is correctly connected. Check the fuse.
Repairs other than those described above should only be carried out by an authorised
specialist.
