If there is no apparent damage, try a known
good CD.
Notice: If a label is added to a CD, or more
than one CD is inserted into the slot at a
time, or an attempt is made to play scratched
or damaged CDs, the CD player could be
damaged. While 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.
Do not add any label to a CD, it could get caught
in the CD player. If a CD is recorded on a
