Compact discs are fairly resistant to damage, how-
ever mistracking can occur due to an accumulation
of dirt on the disc surface.
Follow the guidelines below for maximum enjoy-
ment from your CD collection and player.
Do not write on either side of the disc, particu-
larly the non-label side.
Signals are read from the non-label side. 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 prop-
erly, clean it with a soft, dry cloth, wiping straight
out from the centre, along the radius.
