Troubleshooting
6.1
Duty cycle
The wireless DHC accessories operate in the following fre-
quency bands:
• 868,000~868,600 MHz
• 869,400~869,650 MHz
In order to safeguard operation of all devices working in this
range, it is legally required to limit the transmission time of
devices. Limiting the transmission time minimizes the risk
of interference.
The ‘duty cycle’ is the maximum transmission time. It is
the ratio of the time that a device is actively transmitting
in comparison to the measurement period (1 hour), and is
expressed as a percentage of 1 hour.
If the total amount of allowed transmission time is reached,
the DHC accessory will stop transmitting until the time limit
