TROUBLE SHOOTING  
Why can’t some MP3 files be played?  
MP3 Standard only includes: the songs in layer 3 of MPEG1,  
layer 3 of MPEG2 and layer 3 of MPEG2.5. Otherwise, songs  
won’t be played in the player except they are transformed by  
the corresponding software.  
Why doesn’t the memory size displayed under the operation  
system match the figure on the tab?  
The software in the MP3 player takes up a small portion of the  
memory, which coincides with the corresponding standards.  
More about WAV format  
This unit supports WAV files of IMA ADPCM format only. If you  
want to store WAV files of other format in this player, please set  
up a new folder and store the WAV files in it. Don’t put the WAV  
files of other format into the root directory of the player or the  
folder VOICE. Otherwise the player may shut down when play-  
ing such WAV files.  
What causes the MP3 player running slowly?  
Using or deleting files frequently over a long time will generate  
fragments in the flash memory like fragmention of a hard disk.  
Fragmentation slows down the operating speed of the player.  
What if the driver program of the MP3 player has been dam-  
aged?  
Normally this is caused by improper operation. For details,  
please refer to the Upgrade/Renew Software part.  
What if the MP3 player works abnormally, i.e, shutting down?  
When abnormal situation occurred due to improper opera-  
tion, push the POWER ON switch to OFF and then toward ON.  
The restart of the unit will return it to normal operation.  
GB – 29 | MP-350  
 
What if after a long non-use period the player cannot be turned  
on?  
To enlarge the life of the built-in battery, when the battery level is  
too low or in some abnormal situation (shut off), the lithium  
battery will be protected, so it cannot be turned on. You need to
