Condensation
Sudden temperature changes, storage or operation in an extremely
humid environment may cause condensation inside the cabinet
(laser 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 transmit-
ter with a soft cloth before operating the unit.
If trouble 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, and then turn the power on.
Note:
If neither operation above restores the unit, clear all the memory by
resetting it.
 
Clearing all the memory (reset)
Caution:
When you reset, all data is deleted and the settings return to the
default. (DVD initial settings are retained.)
Symptom
Possible cause
The radio makes 
unusual noises 
continuously.
Is the unit placed near the TV or computer?
Is the FM aerial or AM loop aerial placed 
properly? Move the aerial away from the AC 
power lead if it's located nearby.
The preset chan-
nel cannot be re-
called.
Did you remove the plug from the wall sock-
et, or did a power failure occur?
Set the channel again.
Symptom
Possible cause
The remote con-
trol does not op-
erate.
Is the battery polarity correct?
Are the batteries dead?
Is the distance or angle incorrect?
Are there any obstructions in front of the 
unit?
Is the remote control sensor exposed to 
strong light (inverter fluorescent light, direct 
sunlight, etc.)?
Is the remote control for another equipment 
used simultaneously?
The unit cannot 
be turned on with 
the remote con-
trol.
Is the AC power lead of the unit plugged in?
Are the batteries inserted?
