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 subject to strong external interfer-
ence (mechanical shock, excessive static electricity, ab-
normal supply voltage due to lightning, etc.) or if it is oper-
ated incorrectly, it may malfunction.
If such a problem occurs, do the following:
1
Set the unit to the standby 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 all devices connected to the unit. Then, set the
unit to the power standby mode. Carrying the unit with
other devices left connected or discs left inside might dam-
age the unit.
Care of discs
Discs are fairly resistant to damage. However mistracking
can occur due to accumulation of dirt on the surface.
Do not mark on the non-label side of the disc from which
signals are read.
Keep your discs away from direct sunlight, heat, and
excessive moisture.
Always hold the discs by the edges. Fingerprints, dirt,
or water on the CDs can cause noise or mistracking.
Clean it with a soft, dry cloth, wiping straight out from the
center, along the radius.

Maintenance

Cleaning the cabinet
Periodically wipe the cabinet with a soft cloth and a diluted
soap solution, then with a dry cloth.
Caution:
Do not use chemicals for cleaning (gasoline, paint thin-
ner, etc.). It may damage the cabinet.
Do not apply oil to the inside of the unit. It may cause
malfunctions.
Cleaning the CD pickup lens
In order to ensure proper operation of the CD player,
preventative maintenance (cleaning of the laser pickup
lens) should be performed periodically. Lens cleaners are
commercially available. Contact your local CD software
dealer for options.
