audio files. Mp3 and Wav cannot co-exist within each folder. Rename them "001.mp3/wav" to "255.mp3/wav" as shown below. For
the quickest timely response once triggered; we suggest that no more than 100 sound files in each folder.
4). After everything is done as above, safely disconnect the module with computer. Power it on and push any of the 20 buttons to
play a sound randomly in the associated folder. For example, by pushing the button associated with input "K7". It will randomly
play a sound file from the associated folder "07" and stop; push it again, it will randomly play another sound file from the
associated folder "07" and stop, etc.

subject to the mode configured in the on-board flash memory.
