During normal operation, the duty cycle is not usually
reached. However, repeated and wireless-intensive
teach-in processes mean that it may be reached in iso-
lated instances during start-up or initial installation of a
system. If the duty cycle is exceeded, this is indicated
by one long and one short red flash of the device LED,
and may manifest itself in the device temporarily wor-
king incorrectly. The device will start working correctly
again after a short period (max. 1 hour).
