Causes
No MP3/WMA tracks are
recorded on the disc.
MP3/WMA tracks do not have
the extension code <.mp3> or
<.wma> in their track names.
MP3/WMA tracks are not
recorded in the format
compliant with ISO 9660 Level
1, Level 2, Romeo, or Joliet.
Tracks are not encoded in an
appropriate format.
WMA tracks are copy-
protected.
The track played back is not
an MP3/WMA track (although
it has the extension code
<.mp3> or <.wma>).
Readout time varies due to
the complexity of the folder/
track configuration.
Playback order is determined
when the tracks are recorded.
This sometimes occurs during
play. This is caused by how
the tracks are recorded on the
disc.
The current disc does not
contain any MP3/WMA track.
The current folder does not
contain any MP3/WMA track.
Only <jml> and/or <jma> files
are recorded on the disc.
This unit can only display
alphabets (capital: A–Z, small:
a – z), numbers, and a limited
number of symbols.
Remedies
Change the disc.
Add the extension code
<.mp3> or <.wma> to their track
names.
Change the disc.

encoded in an appropriate
format.

tracks cannot be played back.
Skip to another track or change
the disc. (Do not add the
extension code <.mp3> or
<.wma> to non-MP3/WMA
tracks.)
Do not use too many hierarchies
and folders.
Insert a disc that contains MP3/
WMA tracks.
Select another folder that
contains MP3/WMA tracks.
