Notes on playing MP3 (DPX-MP4030)
This unit can play MP3(MPEG1, 2, 2.5 Audio Layer 3). Note,
however, that the MP3 recording media and formats acceptable
are limited. When writing MP3, pay attention to the following
restrictions.

Acceptable media

The MP3 recording media acceptable to this unit are CD-ROM, CD-R,
and CD-RW.
When using CD-RW, do full format not quick format to prevent
malfunction.

Acceptable medium formats

The following formats are available for the media used in this unit. The
maximum number of characters used for file name including the
delimiter (".") and three-character extension are indicated in
parentheses.
•ISO 9660 Level 1 (12 characters)
•ISO 9660 Level 2 (31 characters)
•Joliet (64 characters)
•Romeo (128 characters)
Up to 200 characters can be displayed in the long file name format.
For a list of available characters, see the instruction manual of the
writing software and the section Entering file and folder names below.
The media reproducible on this unit has the following limitations:
•Maximum number of directory levels: 8
•Maximum number of files per folder: 255
•Maximum number of characters for folder name: 64
•Maximum number of folders: 50
MP3 written in the formats other than the above may not be
successfully played and their file names or folder names are not
properly displayed.

Settings for your CD writer

When you use your CD writer to record MP3 up to the maximum disc
capacity, disable additional writing. For recording on an empty disc up
to the maximum capacity at once, check Disc at Once.

Entering ID3 tag

The Displayable ID3 tag is ID3 version
1.x.
For the character code, refer to the
List of Codes.

Entering file and folder names

The code list characters are the only
file names and folder names that can
be entered and displayed.
If you use any other character for
entry, the file and folder names are not displayed correctly. They may
neither be displayed correctly depending on the CD writer used.
The unit recognizes and plays only those MP3 which have the MP3
extension (.MP3).
A file with a name entered with characters not on the code list
may not play correctly.

Writing files into a medium

When a medium containing MP3 data is loaded, the unit checks all the
data on the medium. If the medium contains a lot of folders or non-
MP3 files, therefore, it takes a long time until the unit starts playing
MP3.
In addition, it may take time for the unit to move to the next MP3 file
or a File Search or Folder Search may not be performed smoothly.
Loading such a medium may produce loud noise to damage the speakers.
•Do no attempt to play a medium containing a non-MP3 file with the
MP3 extension.
The unit mistakes non-MP3 files for MP3 data as long as they have
the MP3 extension.
•Do not attempt to play a medium containing non MP3.
