Notes on CD-Rs/RWs
¡ You may have trouble playing back some CD-R/RW discs recorded on CD recorders (CD-R/RW drives), either 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 and make playback impossible.
¡ Some CD-R/RWs can not be played back successfully thanks to incompatibility among writing software, a CD recorder
(CD-R/RW drive) and the discs.
¡ 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 or MP3/WMA data (Only for CQ-
C3400/C3300W).
¡ Be sure to observe the instructions of CD-R/RW disc for handling it.
