Notes on playing MP3/WMA
This unit can play MP3 (MPEG1 Audio Layer 3)/WMA.
Note, however, that the MP3/WMA recording media
and formats acceptable are limited. When writing
MP3/WMA, pay attention to the following restrictions.
Acceptable media
The MP3/WMA 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 170 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: 100
MP3/WMA 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 MP3/WMA encoder and CD
writer
Do the following setting when compressing audio data in
MP3/WMA data with the MP3/WMA encoder.
• Transfer bit rate: MP3: 8 —320 kbps
WMA: 48 —192 kbps
• Sampling frequency: MP3: 32, 44.1, 48 kHz
WMA: 32, 44.1, 48 kHz
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.
Play mode may not be possible when portions of the
functions of Windows Media Player 9 or higher are used.
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/WMA which
have the MP3/WMA extension (.MP3/.WMA).
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/WMA data is loaded, the
unit checks all the data on the medium. If the medium
contains a lot of folders or non-MP3/WMA files, therefore,
it takes a long time until the unit starts playing MP3/WMA.
In addition, it may take time for the unit to move to the
next MP3/WMA 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/WMA file with the MP3/WMA extension.
The unit mistakes non-MP3/WMA files for MP3/WMA data
as long as they have the MP3/WMA extension.
• Do not attempt to play a medium containing non
MP3/WMA.
MP3/WMA playing order
When selected for play, Folder Search, File Search, or for
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",
depending on your CD writer.
