About CD accessories
●
Do not use accessories
(stabilizers, protective seals, laser lens
cleaners, etc.) sold for メimproving
sound performanceメ or メprotecting
CDs.メ The changes in CD thickness
or outside dimensions made
by these accessories may cause
problems in the player.
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 main unit. Flakes from the
rough edges may also stick to the
recorded surface and interfere with
playback.
●
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 quality (and
antivibration effect), but they can
do more harm than good in regular
uses. The most common problems
are disc insertion, disc ejections,
and won't play problems due to the
protector ring that came off in the
disc mechanism.
