• Handling compact discs
o Always handle a disc with care so that its surface
is
not
scratched.
o 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.
o
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.
o
Do
not warp discs.
o When a disc
is
not currently being used, remove it
ITom
this unit and store it
in
an appropriate case.
o When removing or storing a disc, be careful not to
scratch the playing surface.
o 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.

of
disc cleaner, record spray, anti-static spray or liquid, or
any other chemical-based liquid as such substances
