■ Handling compact discs
• Always handle a disc with care so that its surface is not
scratched.
• Compact discs are rarely worn out 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 a disc. Do not use a
ball-point pen, pencil, or other hard-tipped writing
tools as these may damage the disc and may adversely
affect the disc playback.
• Do not warp discs.
• When a disc is not currently being used, remove it from
this unit and store it 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 must be kept clean. Wipe the disc surface with
a clean, cry cloth. Do not wipe the disc surface with a
circular motion; wipe it straight outward from the
center.
• Do not try to clean the disc surface with any type of
disc cleaner, record spray, anti-static spray or liquid, or
any other chemical-based liquid as such substances
may irreparably damage the disc surface.
• Do not expose discs to direct sunlight, high
temperature, or high humidity for a long period of time
as these conditions may warp or otherwise damage the
disc.
• To play back an 8-cm (3-inch) compact disc, place it in
the inner recessed area of the disc tray. Do not put a
normal 12-cm CD on top of an 8-cm CD.
