Notes on CD-Rs/RWs

You may have trouble playing back some CD-R/RW discs recorded on CD recorders (CD-R/RW drives), ei-

ther due to their recording characteristics or dirt, fingerprints, scratches, etc. on the disc surface.

CD-R/RW discs are less resistant to high temperatures and high humidity than ordinary music CDs. Leaving

them inside a car for extended periods may damage them and make playback impossible.

The unit may not successfully play back a CD-R/RW that was made by the combination of writing software, a

CD recorder (CD-R/RW drive) and a disc if they are incompatible one another.

This player cannot play the CD-R/RW discs if the session is not closed.

This player cannot play the CD-R/RW discs which contains other than CD-DA data.
