Trouble shooting
Cause 1:
Mains lead not plugged in correctly.

Check connection, push connector in firmly.
Cause 1:
Incorrectly inserted batteries or flat batteries in the remote control handset.
Remedy:
Re-install batteries correctly or fit new ones.
Cause 2:
The remote control transmitter has no direct line-of-sight with the .
Remedy:
Make sure that the remote control transmitter has direct line-of-sight contact
with the receiver - note that glass doors can interrupt the connection.
Maximum range between transmitter and receiver: approx. 8 metres.
Be sure to position the receiver where it is not subjected to direct sunlight or
very bright artificial light. Fluorescent tubes and energy-saving lamps are
powerful sources of interference.
Cause:
The loudspeaker cables are connected with reversed polarity.
Remedy:
Check the speaker connections at the loudspeakers and at the amplifier's
speaker terminals; correct if necessary.
Cause:
Poor contact between the Cinch plugs and sockets, or a faulty Cinch cable.
Remedy:
Please check all connections and cables thoroughly.
Cause:
The antenna lead is routed too close to a mains, remote control or audio signal
cable.
Remedy:
Move the leads so that they are spaced well apart. Use the domestic (loft or
outside) antenna or a cable connection.
Cause 1:
The station is not broadcasting RDS information.
Cause 2:
Reception is poor, interference is severe, or the field strength (signal strength)
is low.
Remedy:
Select only those stations which can be received with a strong signal: hiss-free
and without interference.
Cause:
The antenna system or antenna cable is faulty.

Remedy:
Check the antenna lead for good contact at the antenna socket (at the wall)
and in the back of the tuner. As a test, try using the system with a trailing
antenna. If you can now receive stations reasonably well, we recommend that
you call out an expert antenna technician to check your antenna system.
