5. Function
5.1.1 When there is no pairing information, press the button for 5 seconds to enter pairing mode, and the LED starts flashing at 2Hz (DSBC-101-1 DSBC-101-3)/1Hz (DSBC-101-2) frequency.
5.1.2 If the pairing is successful, the LED will be on for 2 seconds and the off.
5.1.3 If the pairing is not successful within 60 seconds, the LED will turn off and exit the pairing mode.
5.1.4 When there is pairing information, press the button for 5 seconds, and the LED starts flashing at 1Hz frequency. At this time, release the button. If you press the button again within 2 seconds and hold it for 5 seconds, the LED flashes at 2Hz frequency to clear the pairing and launch the pairing broadcast. If the button is not pressed again within 2seconds, the LED will stop flashing.
