Care of the housing
The surface and the printing on the housing are largely scratch-resistant. The A 30.3 can be
cleaned with mild soapy water or a gentle glass cleaner and a soft duster.
ATTENTION:
Do not allow any liquid to enter the inside of the housing during cleaning. In
addition, for safety reasons, the power cord should be disconnected before damp wiping. Do
not use solvents or abrasive cleaners that could damage the surface or printing on the housing.
3.2
Troubleshooting
Often, supposed defects can be traced back to operating errors. Sometimes other components
connected to the A 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, e.g. by resetting the device to the factory settings - see
RESET
in section 2.9.
1. No music playback
a) Accidentally switching to stand-by mode via remote control. Press the on/off button (2).
b) If the display is dark and the operation indicator LED (1) is not lit, the mains fuse may be
defective. Since this is usually caused by a defect in the power supply unit or amplifier
electronics (e.g. due to a lightning strike), please contact your dealer.
c) The unit has automatically gone into standby mode after a period of 20 minutes without
playing music or activating a function on the unit (see section 2.10)
2. The device switches off during operation
a)
If no music is played for a period of 20 minutes or if a function on the unit is activated, the
automatic switch-off function of the unit is activated and the unit switches automatically to
standby mode (see section 2.10
Automatic switch-off).
b)
One of the protective circuits of the unit (e.g. overload, overtemperature, short circuit) has
responded. Please contact your specialist dealer.
3. Remote control without function
a)
The batteries of the remote control are empty. Please replace the batteries (see section
1.15.1)
b)
There is no direct connection between the remote control and the device or the distance is
too great.
