Duty cycle  
The duty cycle is a legally regulated limit of the transmission time of de-  
vices 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  
ends. Homematic IP devices are designed and produced with 100% con-  
formity to this regulation.  
During normal operation, the duty cycle is not usually reached. How-  
ever, repeated and radio-intensive pairing 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 flash of  
the device LED (D) , and it may have the effect of the device temporarily  
working incorrectly. The device will start working correctly again after a  
short period (max. 1 hour).
