The integrated evaluation logic assures that the re-transmitted signals are not sent on a sustained basis among systems when several repeater stations are used (to avoid a Ping-Pong effect).

The capacity is calculated in  such a way that the battery  in a hand-held sender being used 10 times a day for one second, has a theoretical life of app. 2 to 3 years. However, the operation at low temperatures or constant use can significantly reduce the capacity.

As long as the hand-held sender is not used significantly more, we recommend to regularly replace the battery every 1 to 1.5 years.
