ISSUE # 2 WHY DOES MY MP3 PLAYER READ “NO FILE”

If your MP3 player reads no file after you have transferred files into the unit 
then it simply means you have transferred an invalid file format into the unit. 

Make sure the file is an MP3 or WMA file. 
 

If your MP3 player reads system error, it means the firmware is corrupted. You 
will need to reset the firmware on the unit. (See issue# 10). 
 

This error message indicates that the MP3 player memory is full. To add new 
songs to the MP3 player, you will need to create space by deleting existing files.  
 

Connect the MP3 player to the USB port of your computer. Copy and Paste or 
Drag and Drop your MP3 files from your source folder into the MP3 player 
(removable drive). You cannot directly download an MP3 file from a website into 
the MP3 player. The files need to be saved on your computer first. 
 

If your MP3 player shows the black squares then it means the firmware is 
corrupted. The firmware needs to be reset/upgraded. See issue# 10. 
 

If your MP3 player freezes in play mode, it means you are using a WMA file with DRM (Digital 
Rights Management). The WMA file is a protected file and cannot be played on the MP3 player. 
 

If the MP3 player freezes on COBY as soon as it is turned on, it means a corrupted file(s) has 
been transferred into the player. You will need to remove/delete the file(s) from the MP3 player 
by formatting the MP3 player.
