●
You may notice that some brand new discs are rough around
the center hole or outside. In this case, remove burrs or flakes
around the edge using the side of a ballpoint pen before using a
new disc. Not doing so may result in burrs or flakes becoming
stuck on the recording side, preventing playback.
●
Do not use a rental disc with glue or remnants of adhesive tape
or labels. They may cause the disc to get stuck inside or
damage the main unit.
Specially-shaped or octagonal CDs, like heart-shaped cannot be
played. Do not attempt to play such discs even with an adapter.
Otherwise the player may be damaged.
●
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.
●
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 discs and to improve
sound quality (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 protector ring that may have come off in the disc
mechanism.
