connecting the on-board flash memory to PC though a USB cable. Just like using a USB flash drive, you can load and
delete audio files easily. If there is a micro SD card detected, it always work with the micro SD card.

index sequence. In another word, the audio file that is the first to be put in the memory is going to work with trigger 1,

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.
