o Never use commercially-available CD stabilizers. Doing so could
make the disc unplayable or damage the unit.
o Do not use cracked discs because they could damage the unit.
o Never use discs with irregular shapes, including heart-shaped and
octagonal discs, because they could damage the unit.
o Do not use printable discs, which allow printing on the label
side. Since the surface of such a disc has been specially treated, if
loaded, it might become stuck in the unit or damage the unit.
If you have any questions about how to handle a CD-R or
CD-RW disc, contact the manufacturer of the disc directly.
