12. Troubleshooting

With the Renkforce car radio, you have purchased a product built to the state of the art and operationally safe. If you
encounter any problems or interferences nevertheless, the following explanations may help in troubleshooting.
No playback, no display, and the lights are out
• Car fuse defective. Look up the respective fuse in the operation manual of your car. Check the fuse.
• The fuse of the car radio is defective. Remove the device and check the fuse.
• The positive line/earth line is loose. Remove the device and check the connections of the cables.
Playback only through one speaker
• The balance control is wrongly adjusted. Adjust the balance control as described.
• The speaker connection has come loose. Remove the device and/or speakers and check the connections.
Playback 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 device and/or speakers and check the connections.
The device mutes in DAB operation
• In contrast to FM reception, where reception interferences will cause interference noise, DAB is muted if the
reception is bad. This is often due to the station supply being not as well developed yet, in particular in rural areas.
This is not a device problem.
• The DAB aerial was placed in an unsuitable place (e.g. too close to the vehicle's sheet metal parts or behind a
metal-vaporised vehicle window). Use a DAB outer aerial if there is no better installation option.
• The DAB aerial connection has come loose from the device. Remove the device and check the connection.
In FM 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 device and check the connection.
• The aerial is defective. Check the connection, earthing and the aerial itself.
