For the first step, it was chosen to program the units to record 15 minutes and pause for the next 5 minutes, repeating.

To program the units, the UM384BLE application ( https://bit.ly/38DlJuS ) must be installed on an ANDROID phone/tablet.

Once the application is installed, and once it is launched, one must select CONNECT TO MIC and then SCAN&CONNECT. Only then should you insert the batteries into the unit, or reboot the unit by removing the magnet located outside the reset point.

Once you have installed the app you can follow, step by step, what is shown in the video.
