following error messages, there may be an incorrect setting or there
may be a problem with the disc that you are trying to play.

NO DISC
DISC ERROR
INSERT DISC
Follow these steps to try to resolve this issue:

IMPORTANT: Not all CD/DVD players are supplied with the same
functions and/or features. To verify model-specific information on
any of these steps, refer to the instructions supplied with the
product.

If there is a HOLD switch or function available for the player, make
sure that the switch or the function is set OFF.
Verify the disc that you are trying to play is supported by the player.
NOTE: There are some disc players that do not support VCD or DVD
discs, as well as not supporting CD-R or CD-RW discs created by a
CD burner. For information regarding disc compatibility with your
unit, refer to the operating instructions.

Try playing a couple of different commercially-produced discs.
NOTE: If more than one commercially-produced disc does not play,
verify whether the discs are extended-length discs. Some players
are not able to play discs where the recording exceeds the standard
74 minutes. If the recording of the disc is longer than 74 minutes, it
is possible that some of the specifications of that disc were
compromised and therefore, the CD player will not recognize that
disc.

Verify that the disc is inserted correctly, with the playback side of
the disc facing down in the disc tray.
If the disc is dirty with fingerprints or smudges, or if the disc is
scratched or broken, the player may not recognize the disc, clean
the disc using a soft, dry cloth.
