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: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 kHz
WMA: 32, 44.1, 48 kHz
When you use your CD writer to record MP3/WMA
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.
