and Audio CD operation
This unit can playback the MP3/JPEG/DivX
®
-data which has been recorded on CD-R/RW. Audio CD also can be played back.
To produce the MP3/JPEG/DivX
®
-data, you need a Windows-PC with CD-RW drive and a MP3/JPEG/DivX
®
-encoding Software
(not supplied). The Apple-HFS-System cannot be played. This unit requires discs/recordings to meet certain technical standards
in order to achieve optimal playback quality.
There are many different types of recordable disc formats (including CD-R containing MP3 files). Not all recordable discs will
produce optimal playback quality. The technical criteria set forth in this instruction manual are meant only as a guide.
Use of CD-RW for MP3 files is not recommended.
