4 Appendix
4.1 Cleaning
Use a soft cloth and normal glass cleansing fluid.
CAUTION:
Make sure that no fluid comes into the unit. Do not use scouring cleaners.
They may damage the surface.
4.2 Troubleshooting
Some putative defects are often caused by small mistakes in operation. Sometimes, other
units connected to the amplifier may cause problems, too. We therefore kindly ask you to
read the following tips first, before consulting your dealer or us.
1. No playback
Mute function is active, press button MUTE on your remote control or increase the
volume using the volume knob or the volume keys on remote control.
2. Inadvertent switching to stand by.
Turn the operation selector to On. If the LED indicator does not light up, a fuse might be
blown due to overvoltage (e.g. in case of a thunderstorm etc.). Please contact your dealer.
4.3 Conditions of warranty (EC only)
