Notes on MP3 discs
 When a disc is loaded, the unit reads all the files
on that disc. During this time, "READ" is blinking. If
there are many folders or non-MP3 files on the

folders are excluded when creating MP3 discs.
 During playback, folders that contain no MP3 files
are skipped.

extension of ".mp3".

extension but the actual file was created in a
different audio format, this unit may produce
noise or may malfunction.
