The device is muted in DAB mode
•
Unlike normal radio operation, where interfering noise is caused by reception interferences, the DAB playback is
muted when reception is poor. This is often explained by underdeveloped communication infrastructure, especially
in rural areas. This is by no means a problem with your device.
•
The DAB antenna was not properly installed, for example, too close to the vehicle's sheet metal parts or behind
a metallised windscreen part. If a proper installation of the DAB antenna is not possible, use an external DAB
antenna.
•
The DAB antenna is not properly connected to/detached from the device or not connected to the antenna control
output. Remove the device and check the connections.
No stations are received by the FM radio
•
The antenna is not pulled out completely. Pull the antenna out to its full length.
•
The antenna connection has come loose. Remove the device and check the connection.
•
The antenna is defective. Check the connection, grounding and antenna itself.
Faulty radio, USB or SD memory card
•
Interferences reach the device via the positive line. Install an additional interference suppression coil into the
positive line.
•
If necessary, equip your vehicle with spark-plug suppressor sockets, distributor arms etc. to suppress interferences.
•
Bad ground connection. Check the ground connection; use a different ground connection if necessary.
