Care 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.
● 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

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

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.
