4.1 Care of the housing
The surface and the printing on the housing are largely scratch-resistant. The CD 30.3 can be
cleaned with mild soapy water or a gentle glass cleaner and a soft duster.
ATTENTION
: During cleaning, liquid must never be allowed to enter the interior of the housing.
In addition, for safety reasons, the power cord should be disconnected before wiping the CD
30.3 with a damp cloth. Do not use any solvents or abrasive cleaners that could damage the
surface or printing on the housing.
4.2 Troubleshooting
Often alleged defects can be traced back to operating errors, sometimes other devices
connected to the CD 30.3 are also responsible for a malfunction. Before you contact your dealer
or us about a defect, please check the following list to see if you can correct the malfunction
yourself.
1. No music playback
a) The
MUTE
function (via remote control RC 8) is active. Deactivate it.
b) Accidentally switch to stand-by. Press the power key (1).
c) If the display (7) is dark and the blue LED (6) is not lit, the mains fuse may be defective. Since
this is usually caused by a defect of the power supply unit or the other electronics (e.g. due to
lightning), please contact your dealer.
2. Remote control without function
a) The batteries of the remote control are flat. Please replace the batteries (see section 1.8.1).
b) There is no direct connection between the remote control and the unit or the distance is
too great. One of the protective circuits of the unit (e.g. overload, overtemperature, short
circuit) has responded. Please contact your specialist dealer.
3. A CD was inserted, but "no disc" appears in the display
a) Es wurde entweder eine verschmutzte oder defekte CD eingelegt oder die CD wurde falsch
herum eingelegt (Etikettenseite nach unten statt nach oben).
