File extensions
Always add a file extension ".MP3" to MP3 file
by using single byte letters. If you add a file
extension other than specified or forget to add
the file extension, the file cannot be played.
Never simply change any file extension to
".MP3" as this will cause unexpected result
and may damage the unit as well. Please use
appropriate audio converter to change to valid
mp3 files.
Logical format ( File system )
1. When writing MP3 file on a SD/MMC card,
please select "FAT12" or "FAT16" as the
system file format. Please be aware that the
Windows XP will format any volume of 512MB
or larger with FAT32 by default. Thus, if the disk
is using "FAT32" system file format, please
format the disk with "FAT" system file format
which is "FAT16". All the data will be erased
during formatting. Thus, please backup your
data accordingly.
2. The folder name and file name can be dis-
played as the title during MP3 play but the
title must be within 30 single byte alphabetical
letters and numerals ( not including a file exten-
sion ) . Longer name will not be displayed.
