Programming/Test button: short press to set programming mode. If this button is held while connecting the battery, it enters the safe mode.
Programming LED: programming mode indicator (red). When the device enters the safe mode, it blinks (red) every half second. During the start-up
(reset or after power failure) and if the device is not in safe mode, it emits a red flash.

¹ See "Note about the batteries".
² Considering one hearbeat sending each day, 7 open/close cycles per day and medium signal power.
³ The maximum consumption depends on the transmission power parameterized.
⁴ The maximum range depends on several factors such as environmental conditions, device orientation, type and thickness of the surrounding materials,
etc.
