Troubleshooting chart (continued)
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.
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.
Caution:
This operation will erase all data stored in memory
including clock, timer settings, tuner preset, and CD
program.
Remove all CDs 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.
Compact discs are fairly resistant to damage, however
mistracking can occur due to an accumulation of dirt on the
disc surface. Follow the guidelines below for maximum
enjoyment from your CD collection and player.
● Do not write on either side of the disc, particularly the
non-label side from which signals are read. Do not
mark this surface.
● Keep your discs away from direct sunlight, heat, and
excessive moisture.
● Always hold the CDs by the edges. Fingerprints, dirt, or
water on the CDs can cause noise or mistracking. If a
CD is dirty or does not play properly, clean it with a soft,
dry cloth, wiping straight out from the center, along the
radius.
Maintenance
Periodically wipe the cabinet with a soft cloth and a diluted
soap solution, then with a dry cloth.
