When using CD-RW, do full format not quick format to prevent

Settings for your MP3/WMA encoder and CD writer

Entering ID3 tag and Contents
Description
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
with the MP3/WMA extension.
The unit mistakes non-MP3/WMA
they have the MP3/WMA extension.
• Do not attempt to play a medium containing non MP3/WMA.
