3). Insert the prepared SD card(face up) with the MP3 files into the SD slot of the player correctly.
4). Switch on the player, then the player directly reads the MP3 files from the micro SD card and plays back when the
sensor detects a human body.
2. Steps for using the internal flash memory
1). Firstly, repeat the 4 steps above for using a micro SD card.
2). Make sure the size of the MP3 files in the micro SD card is not large than the internal flash memory(2MB).
3). Then long press the key B by about 5 seconds at the play state, and don't remove your finger until you see the
indicator LED flashing(the duration time of flashing is about 10 seconds). When the indicator LED stops flashing, it
means the MP3 files from the SD card are successfully copied to the internal flash memory.
4). Take out the micro SD card and re-switch it on. Now the player can work normally with your MP3 files in the flash
memory.
Mode Switching
No matter you use a micro SD card directly or use the internal flash memory, the two triggering modes always exist.
Long press the key A by about 3 seconds at the play state, and at this moment if the indicator LED flashes one time, it
means now the work mode is switched to all loop in a cycle one by one repeat work mode; if the indicator LED flashes
two times continuously, it means now the work mode is switched to the single repeat work mode.
