Remote control

does not operate.

The radio makes
unusual noises
continuously.
Condensation
Sudden temperature changes, storage or operation in an extremely
humid environment may cause condensation inside the cabinet (CD
pickup, etc.) or on the transmitter 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 power on.
Note:
If neither operation above restores the unit, clear all the memory by
resetting it.
Before transporting the unit
Remove the CD from the unit. Make sure there is no CD in the disc
tray. Then, set the unit to the power stand-by mode. Carrying the unit
with discs left inside can damage the unit.
