Many potential problems can be resolved by the owner
without calling a service technician.
If something is wrong with this product, check the following
before calling your authorised SHARP dealer or service
centre.

Sudden temperature changes, storage or operation in an
extremely humid environment may cause condensation
inside the cabinet. Condensation can cause the unit to

normal playback is possible (about 1 hour). Wipe off any
condensation on the transmitter with a soft cloth before
operating the unit.

When this product is subject to strong external interference
(mechanical shock, excessive static electricity, abnormal
supply voltage due to lightning, etc.) or if it is operated
incorrectly, it may malfunction.
If the unit is not restored in the previous operation, 
unplug and plug in the unit again

unplug all component connected and plug in again.

Periodically wipe the cabinet with a soft cloth.
