Care of compact discs
Q
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
O
which signals are read. Do not mark this surface.
Keep your discs away from direct sunlight, heat, and excessive
O
moisture.
Always hold the CDs by the edges. Fingerprints, dirt, or water on the
O
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.
Cleaning the cabinet
Q
Maintenance
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 thinner, etc.). It may
O
damage the cabinet.
Do not apply oil to the inside of the unit. It may cause malfunctions.
O
Cleaning the CD pickup lens
Q
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.
