6.3 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 limit is exceeded, this is indicated by the LED (A)
emitting a long red flash, and the device may temporarily not function.
The device will start working correctly again after a short period (max. 1
hour).
7 Restoring factory settings
The device's factory settings can be restored. If you do this, you will
lose all your settings.
To restore the factory settings of the device, please proceed as follows:
• Press and hold down the system button (A) for 4 seconds, until
the LED (A) starts quickly flashing orange (fig. 13).
• Release the system button.
• Press and hold down the system button for 4 seconds again, until
the LED lights up green (fig. 14).
• Release the system button again to conclude the procedure.
The device will perform a restart.
