9). Safely disconnect the module with computer.
10). Apply power to the module and push any of 20 buttons to play a corresponding sound.

3.3. 'One-on-one' folder triggering control (for random playback of the sound files in the associated
folder)
In order to meet different needs, we added 'one-on-one' folder triggering control except for the traditional 'One-on-one' triggering
of sound files. 'One-on-one' folder triggering control is used for random playback of the sound files in the associated folder. In
other words, each of 20 input triggers can play multiple sound files in the corresponding folders in random order. The traditional
'one-on-one' triggering control mode is that each of the 20 input triggers can only activate a single corresponding sound file. Both
of these two triggering control modes can't co-exist. Users can only choose one type to use. Please refer to the following steps on
how to loading files when choosing 'one-on-one' folder triggering control.
1). The micro SD card that will contain the audio files must be formatted to FAT32 before loading files and folders. If the on-board
flash memory is large enough and chosen to use, reformatting is not required and the original file system FAT needs to be kept.
2). Build 20 folders and rename them from "01" to "20" in the root directory of the on-board flash memory or the micro SD card.
The input "K1" associates with folder "01", the input "K2" associates with folder "02"...... the input "K20" associates with folder "20".
Put the prepared configuration file together with the folders in the root directory of the on-board flash memory or the micro SD
card as below.
