Care of Your CD and DVD Player
Do not add any label to a CD, it could get caught in the
CD or DVD 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.
The use of CD lens cleaners for CDs is not advised, due
to the risk of contaminating the lens of the CD optics
with lubricants internal to the CD and DVD player
mechanism.
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.
If an error displays, see "CD Messages" later in this
section.
