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.
