Trouble shooting
Many problems have a simple cause and a correspondingly simple solution. The following section describes a few
difficulties you may encounter, and the measures you need to take to cure them. If you find it impossible to solve a
problem with the help of these notes please disconnect the unit from the mains and ask your authorised

specialist dealer for advice.
Machine does not switch on Cause 1:
Mains lead not plugged in correctly.
Remedy:
Check connection, push connector in firmly.
Cause 2:
Mains switch on the back panel not switched on.
Remedy:
Switch the mains switch on.
Device makes click noises
Cause :
The clicking is caused by the gold contact relays. These are responsible for
the volume control, switching and muting of the audio signal. Relays are the
technically best solution for these applications. Therefore, clicking is a
quality feature and not a shortcoming.
FM radio
Whistling or whispering
noises from the speakers.
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.
The RDS station name does
not appear in the display. 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.
The unit can be operated
normally, but very few
stations or none at all can be
picked up. 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.
