Before Using the Audio and Visual System
■
Brand new CDs
• You may notice that some brand new discs have "rough edges" around the
center hole or outside. In such cases, remove the "rough edges" or flakes
around the edge using the side of a ballpoint pen before using the new disc.
Not doing so may result in the "rough edges" or flakes attaching to the
recording side, preventing playback.

Rental discs
• Do not use a rental disc with glue or remnants of adhesive tape or labels
attached to the disc.
They may cause the disc to get stuck inside or damage the unit.

Irregularly-shaped CDs
• Irregularly-shaped discs, such as octagonal CDs or heart-shaped CDs, cannot
be played. Do not play this type of disc, even with an adapter.
Damage to the player could result.
■
Disc accessories
• Do not use accessories (such as stabilizers, protective seals, laser lens cleaners)
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.
