Precautions when creating MP3/WMA
files on a computer
o Only discs that have been recorded using the ISO
9660 standard can be played by this unit.
o MP3 and WMA files are recognized by their file exten-
sions (“.mp3” for MP3 files and “.wma” for WMA files.)
Always include the extension in the file name.
o Files without extensions cannot be recognized. A file
cannot be played back regardless of the file name
extension, if the data is not in the MP3 or WMA
format.
o After recording to a CD-R/CD-RW, always close the
session (complete disc creation). This unit cannot
play a disc if its session has not been closed.
o A maximum of 999 files and 99 folders on a disc can
be played. If the media has more than these maxi-
mums, this unit might not be able to correctly play
any file that is the 1000th or higher or any folder that
is the 100th or higher.
o Discs made with multi-session recording are not sup-
ported. Only the first session can be played back.
o Depending on the condition of the disc, playback
might not be possible or the sound might skip.
o This unit cannot play copyright-protected audio files.
