• 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.
