Handling of disc
• When holding a CD-R, CD-RW or CD disc, be careful not
to leave a fingerprint, dirt or a scratch on the signal-
recording side. Hold the disc by placing your fingers on
the edge or across the center hole and edge. A disc
containing a fingerprint, dirt or a scratch can sometimes
become unusable for recording or playback.
• Be careful not to scratch the label side. A scratched disc
can sometimes become unusable for recording or
playback.
• The disc rotates at a high speed inside the player. Do not
attempt to use an abnormal disc (cracked disc, extremely
warped disc, etc.).
Disc maintenance
• When a disc is stained with a fingerprint or dust, the signal
recorded on the disc itself is not affected but such a stain
could degrade the sound quality by reducing the
brightness of the light reflected from the signal recording
side. Therefore, always try to keep the disc surface clean.
For cleaning, use a soft cloth which is either dry or soaked
in alcohol and wipe with a light force in straight directions
from the center toward the edge.
• For disc cleaning, it is recommended to use an optional
disc cleaning kit.
• Do not use record spray or antistatic agent. Also take care
that volatile chemicals such as benzine and thinner do not
spill on the disc, for these substances may corrode the
surface.
Disc storage
• The CD-R, CD-RW and CD discs are made of plastic
material just like analog record so. When storing a disc,
take care so that it does not warp. Always put it in its case
and stand the case upright and avoid places subject to
direct sunlight, high temperatures, high humidity and
extremely low temperatures. It is not recommended to
leave the case on a car seat because the seat of a car in
direct sunlight can become unbelievably hot.
• Be sure to read the instructions provided with the disc.
• Do not stick paper or seals on the label surface.
Make sure the label surface is not scratched or damaged.
Scratched or damaged surfaces may result in playback or
recording failure.
Use only a felt pen sold on the market or similar pen to
write on the label. Never use a writing instrument with a
hard point (ballpoint pen, pencil, etc.), as this will damage
the disc.
Do not wipe in a circular
direction.
Wipe lightly from the
center toward the edge.
Do not play a CD with a special shape
Do not play a CD having other shape than a circular disc,
such as a heart shaped disc. Otherwise malfunction may
occur.
