Entering ID3 Tag
This unit supports ID3 tag versions 1.0 and 1.1.
Entering File and Folder Names
Names using the code list characters are the only file names and folder names that can be entered
and displayed. Using any other character will cause the file and folder names to be displayed
incorrectly. The unit recognizes and plays only files with the MP3/WMA extension.
A file name entered with characters not on the code list may not play correctly.
Writing Files into a Media
When a media containing MP3/WMA data is loaded, the unit checks all data. If the media contains
many folders or non-MP3/WMA files, MP3/WMA play will be delayed, it may take time for the unit to
move to the next file, and searches may not be performed smoothly. Loading such a media may
produce loud noise and cause damage to the speakers. Do not attempt to play a media
containing a non-MP3/WMA file with the MP3/WMA extension or a media containing non
MP3/WMA files.
Bit Rates
The unit supports bit rates from 32 - 320 kbps.
Files Playing Order
When selected for play, Folder Search, File Search or Folder Select, files and folders are accessed
in the order in which they were written by the PC 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. For example, a
media with the following folder/file hierarchy is subject to Folder Search, File Search or Folder
Select as shown below.
An outline of a Media with MP3/WMA is shown below. Subfolders are shown as folders in the
folder currently selected.
