• Entering Tag Configuration Mode - the button must be pressed for 4 seconds on startup. Then 3 LED blinks with period of one second signalize successfully received configuration message and applied reconfiguration. If the battery is low for configuration procedure, then 4 fast (200ms) LED blinks appear. If configuration was not received, then LED will not blink at all.
