Precautions for Playback
Compact discs (CDs) with the following logo on the

Do not use discs designed for purposes other than audio,
such as CD-ROMs for PC use. Abnormal noise could
damage the CD receiver and/or speakers.
* The CD receiver supports CD-R and CD-RW discs.
Note that some discs may not playback because of the disc
characteristics, scratches, contamination or the recording
state. A disc recorded with an audio CD recorder will not
playback unless it is finalized.
Never use discs that have a special shape (such as hearts
or octagons). These types of discs could damage the CD
receiver.
