■ Notes about handling compact discs
• Always handle a disc with care so that its surface is not
scratched.
• Compact discs are not subjected to wear during
playback, but damage to the disc surface when the disc
is being handled can adversely affect the disc playback.
• Be sure to use a felt-tip pen or similar writing tool
when writing on the label side of the disc. Do not use a
ballpoint pen, pencil, or other hard-tipped writing tool,
as these may damage the disc and may adversely affect
the disc playback.
• Do not warp discs.
• When a disc is not being used, remove it from the unit
and store in an appropriate case.
• When removing or storing a disc, be careful not to
scratch the playing surface.
• Compact discs are not affected by small particles of
dust or fingerprints on their playing surface, but even
so they should be kept clean. Wipe by using a clean,
dry cloth.
Do not wipe with a circular motion; wipe straight
outward from the center.
• Do not try to clean the disc's surface by using any type
of disc cleaner, record spray, anti-static spray or liquid,
or any other chemical-based liquid because such
substances might irreparably damage the disc's
surface.
• Do not expose discs to direct sunlight, high
temperature or high humidity for a long period of time,
as these might warp or otherwise damage the disc.
No!
