9.3 Duty cycle

The duty cycle is a legally regulated limit of the

transmission time of devices in the 868 MHz range. The

aim of this regulation is to safeguard the operation of all

devices working in the 868 MHz range.

In the 868 MHz frequency range we use, the maximum

transmission time of any device is 1% of an hour (i.e. 36

seconds in an hour). Devices must cease transmission

when they reach the 1% limit until this time restriction

comes to an end. Homematic IP devices are designed

and produced with 100% conformity to this regulation.

During normal operation, the duty cycle is not usually

reached. However, repeated and radio-intensive teach-

in processes mean that it may be reached in isolated

instances during start-up or initial installation of a

system. If the duty cycle is exceeded, this is indicated

by one long red lighting of the device LED (E), and

may manifest itself in the device temporarily working

incorrectly. The device starts working correctly again

after a short period (max. 1 hour).

10 Restore factory settings

The factory settings of the device can be

restored. If you do this, you will lose all your

settings.
