3). Now choose a storage device between the on-board flash memory and micro SD card to upload your MP3 sound
files. If the total capacity of your 4 MP3 sound files is smaller than 4MB, you can choose to use the flash memory
directly, and if it is larger than 4MB, then choose to use a micro SD card instead. The mini USB port as you see above
is used for connecting the on-board flash memory to PC though a USB cable. Just like using a USB flash drive, you
can load and delete sound files easily. Note: If there is a micro SD card detected, it always work with the micro SD card
and never do with the flash memory unless the micro SD card is taken out.
4). The player automatically matches which sound file associates with which trigger among of 4 based on the physical
index sequence. In another word, the sound file that is the first to be put in the memory is going to work with trigger 1,
and the sound file that is last one to be put in the memory is going to work with trigger 4. Before the sound files are put
in the memory, you can also rename the MP3 sound files as 001.mp3, 002.mp3, 003.mp3, and 004.mp3, and make
sure they are ranked one by one by physical sequence.
5). After everything above is done, assemble the parts back carefully. When it is powered on, it works normally.
