"Correct "Wrong
D Handle compact discs carefully, especially when you set them
into the magazine. Hold them on the edge and do not bend them.
Avoid getting fingerprints on them, particularly on the shiny side.
D Dirt, scrapes, warping, pin holes, or other disc damage could
cause the player to skip or to repeat a section of a track. (To see
a pin hole, hold the disc up to the light.)

AIR CONDITIONING AND AUDIO
To clean a compact disc: Wipe it with a soft, lint−free cloth that has
been dampened with water. Wipe in a straight line from the center
to the edge of the disc (not in a circle). Do not use a conventional
record cleaner or anti−static device.
