PANEL/REAR PLATE/MP3 FUNCTION AND OPERATION
When you need to use the built-in MP3 encoding function, please format your USB disk (U disk
for short below) as FAT32 format in computer first and then copy the file in MP3 format in U disk.
When reading USB disk, the encoding system will engage in encoding playing according to the
generation sequence of MP3 songs file. Therefore, the song which is copied to U disk first will be
played in priority or vice versa. When the user needs to play according to the specific sequence,
they can arrange the copying sequence. If the files copied to U disk can not be played, please
inspect whether the file format is in MP3 format. If not, please switch to MP3 format in computer
and then copy to U disk in order to play normally. When copying MP3 file, you shall copy to the
catalogue of U disk. It is suggested to delete all the unnecessary files and file catalogues in order
to reduce the occurrence of reading error when the encoding is played. When the user buys U
disk, please select the ones with better quality and internal encoding supporting 64MB/128M
