on the remote control. Condensation can cause the unit
to malfunction. If this happens, leave the power on with no
disc in the unit until normal playback is possible (about 1
hour). Wipe off any condensation on the transmitter with a
soft cloth before operating the unit.
■ If problem occurs
When this product is subjected 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 such a problem occurs, do the following:
1 Set the unit to the stand-by mode and turn the power
on again.
2 If the unit is not restored in the previous operation,
unplug and plug in the unit again, and then turn the
