5.8 Downloading Files
In order to load additional audio files to the MP3 player, it must be connected to the USB port
of a USB enabled computer.
First connect the USB download cable to the MIC/USB connector on the MP3 player, then
connect the USB plug into the computer.
NOTE: Not following this order may cause the MP3 player to not be recognized by the
computer. The MIL style connector on the MP3 player does not allow for a ground-first
connection per the USB standard. By connecting the MIL style connector to the MP3 player
first, the standard USB connector will then be allowed to establish a proper connection to the
computer.
After connecting the MP3 player’s USB interface to the computer, the following will be
displayed on the MP3 player after the initial splash screen:
Figure 9: MP3 Player Mass Storage Screen
The computer will automatically install USB mass storage drivers and will display two new
“Removable Mass Storage” devices in the file management interface. The first installed drive
will not be accessible, as this drive is reserved for system memory and is locked. The second
installed drive is available to read and write files. Just drag and drop the files you need.
