Do not stick any paper tape to the recording

Hold the disc without touching the recording
side as this may make the disc dirty and
lead to the audio skipping.
Using benzene, record disc cleaner,
or anti-static fluids may damage the disc.
Using a dirty disc will damage the disc and
lead to audio skipping. When the disc is
dirty, use a commercial disc cleaner to
gently clean it from the inside to the

breakdown.
Adapters or discs with special properties,

New Disc
Some new discs may have burrs found in
the center hole or at the edges. Remove
these burrs with a ballpoint pen, etc. before
using the disc.
If burrs are not removed, the disc may not
be read accurately and cause improper
operation.
Rental Discs
Do not use any disc that has cellophane
tape or any rental disc that has glue from
the label exposed or if some of the removed
label still attached to it. Using the disc like
this may cause the disc to not eject properly
and damage the disc.

Heart-shaped or octagon-shaped discs cannot
be played. Do not use them as they may
cause damage.
Disc Accessories

available accessories (such as stabilizers,

accessories (such as CD rings, protectors)
that are said to improve sound quality or
are effective against vibrations. They may
come off inside the device, causing the disc
to become unplayable or unretrievable and
lead to malfunction.
