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.
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.
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.
