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

Entering ID3 tag
The Displayable ID3 tag is ID3 version 1.x.
For the character code, refer to the List of Codes.
• Some characters cannot be displayed with a specific control
unit.
Entering file names
The code list characters are the only file names that
can be entered and displayed.
If you use any other character for entry, the file 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.
