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 centre, along the radius.

 

Poor performance during CD playback (skipping or jumping) can be
caused by a dirty or contaminated CD laser pick up lens. If this
happens then the use of a commercially available CD lens cleaning
discs may restore normal operation. Contact your supplier or local
CD software dealer to obtain CD lens cleaning discs. Ensure all
included instructions/documentation are carefully followed.
 

Periodically wipe the cabinet with a soft cloth and a diluted soap
solution, then with a dry cloth.

Do not use chemicals for cleaning (petrol, paint thinner, etc.). It
may damage the cabinet finish.
Do not apply oil to the inside of the unit. It may cause
malfunctions.
