If there is no apparent damage, try a known good CD.
Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top
of the recorded CD with a marking pen instead.
Notice: If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any
label, load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
If an error appears on the display, see "CD Messages"
later in this section.
