About new discs
●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. before
using. Rough edges may prevent proper loading in the
unit. Flakes from the rough edges may also stick to the
recorded surface and interfere with playback.
About rental discs
●Do not use CD discs with attached cellophane tape, rental
CD discs with glue protruding from labels or discs with the
residue of peeled adhesives. These discs can prevent the
player from properly opening and closing as well as cause
other damage.
About specially shaped discs
●Specially-shaped CDs cannot be played. Do not attempt
to play them, even with an adapter, since they may
damage the player.
●Do not use commercially available lens cleaners, as they
may cause damage to the pickup of the player.
About disc accessories
●Do not use accessories such as stabilizers, protective
seals or laser lens cleaners sold for "improving sound
performance" or "protecting CDs." Changes in CD
thickness or outside dimensions made by these
accessories may cause problems in the player.
●Do not attach any ring-shape protector (or other
accessory) to your discs. These protectors are
commercially available and said to protect discs and to
improve sound quality (and add an anti-vibration effect),
but they can do more harm than good during regular use.
The most common problems are insert/eject related
problems and "No playback" problems due to the
protector ring coming off in the disc mechanism.
