Writing Files into a Medium
When a medium containing MP3/WMA data is loaded, the unit checks all data. If the medium contains
many folders or non-MP3/WMA files, MP3/WMA play will be delayed, it may take time for the unit to
move to the next file, and searches may not be performed smoothly. Loading such a medium may
produce loud noise and cause damage to the speakers. Do not attempt to play a medium
containing a non-MP3/WMA file with the MP3/WMA extension or a medium containing non
MP3/WMA files.

MP3 Playing Order
When selected for play, Folder Search, File Search or Folder Select, files and folders are accessed in
the order in which they were written by the CD writer. Because of this, the order in which they are
expected to be played may not match the order in which they are actually played. You may be able to
set the order in which MP3/WMA are to be played by writing them onto a medium such as a CD-R with
their file names beginning with play sequence numbers such as "01" to "99". For example, a medium
with the following folder/file hierarchy is subject to Folder Search, File Search or Folder Select as
shown below.
An outline of a CD-ROM with MP3/WMA is shown below. Subfolders are shown as folders in the
folder currently selected.
