About brand new CDs
• You may notice that some brand
new discs are rough around the
center hole or outside edge.
Remove the rough edges with
the side of a ballpoint pen, etc.
Rough edges may prevent
proper loading in the deck.
Flakes from the rough edges
may also stick to the recorded
surface and interfere with
playback.

About CD accessories
• Do not use accessories
(stabilizers, protective seals, laser
lens cleaners, etc.) sold for
"improving sound performance"
or "protecting CDs." The
changes in CD thickness or
outside dimensions made by
these accessories may cause
problems in the player.
Ballpoint
pen
• Please be sure NOT to attach
any ring-shape protector(or
other accessory) to your discs.
Those protectors are commercially
available and said to protect disc
and to improve sound quatily(and
antivibration effect), but they can
do more harm than good in
regular uses. The most common
problems are Insert /Eject
related problems and "No
playback" problems due to the
protectorring that came off in the
disc machanism.
