Playing files with a format not supported will be
skipped, and the scan, random and repeat playback
mode may be canceled.
• File and Disc Not Supported
Files and discs with following extensions are not
supported: *.AAC, *.DLF, *.M3U, *.PLS, *.MP3 PRO
files, files with DRM, open session discs.
• Logical format (File system)
1. When writing an MP3/WMA file on a disc, please
select "ISO9660 level 1 or level 2 (without including
expansion format)" as the writing software format.
Normal playback may not be possible if the disc is
recorded on another format.
2. The folder name and file name can be displayed
as the title during MP3/WMA play but the title
must be within 31 single byte alphabetical letters
and numerals for the folder name and file name
(including an extension). Entering more letters or
numerals than specified may cause an incorrect
display.
• Entering File and Folder Names
Names using the code list characters are the only
file names and folder names that can be entered and
displayed. Using any other character will cause the file
and folder names to be displayed incorrectly.
• Electronic Shock Protection

45 seconds for MP3 recorded at 44.1 kHz, 128 kbps
90 seconds for WMA recorded at 44.1 kHz, 128 kbps
• Folder structure
1. A disc with a folder having more than 8 hierarchical
levels will conflict with the ISO9660 and playback
will be impossible.
• Number of files or folders
1. The maximum allowable number of folders is 255
(including root directory); the maximum allowable
number of files is 1500 (max. 255 per folder). This
represents the maximum number of tracks that can
be played back.
2. Tracks are played in the order that they were
recorded onto a disc. (Tracks might not always be
played in the order displayed on the PC).
• Some noise may occur depending on the type of
encoder software used while recording.
• In case of a track recorded at VBR (variable bit rate),
the display for the play time of the track may be
slightly different from the actual play time. Also, the
recommended value of VBR ranges from 32 kbps to
320 kbps.
• After disc selection, the play mode is automatically
engaged.

Playing MP3 folders
When selected for play, files and folders (Folder
Search, File Search or Folder Select) are accessed
in the order in which they were written to the media.
As a result, 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 files are to be played by assigning 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.
See the diagram below.
The player will only recognize three folder levels and
does not display folders containing other folders. In
the example above, the unit will display folders 2,3, 5
and 7, but 1 and 6 since they do not contain others.
