To specify the playback sequence, the fol-
lowing method is recommended.

Create the file name including numbers
that specify the playback sequence (e.g.,
001xxx.mp3 and 099yyy.mp3).
2
Put those files into a folder.
3
Record the folder containing files into the
USB device.
However, depending on the system environ-
ment, you cannot specify the file playback
sequence.
