QCare of compact discs

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.

ODo not write on either side of the disc, particularly the non-label side from which signals are read. Do not mark this surface.

OKeep your discs away from direct sunlight, heat, and excessive moisture.

OAlways 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

QCleaning 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.

QCleaning the cabinet

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

Caution:

ODo not use chemicals for cleaning (gasoline, paint thinner, etc.). It may damage the cabinet.

ODo not apply oil to the inside of the unit. It may cause malfunctions.
