Insert the player into a USB port while the computer is on; it will receive power and allow data transfer, and the screen will show a “056” indicator.
The player uses one AAA battery and can play music for about 15 hours on a full charge.
Supported formats are MPEGI Layer 3, WAN and VWAV; only standard MP3 (MPEGI Layer 3) files will play correctly.
Format the internal storage to FAT using the player’s format option; this restores the file system.
