For example, when a device has a duty cycle limit of 1%, it
is only allowed to transmit 36 seconds in 1 hour. After this, it
will stop transmitting until the 1 hour limit is reached.
DHC accessories fully comply to this limitation and use 2
frequency bands with a duty cycle of respectively 1 % and
10%.
During normal operation of the DHC accessories, this limit
is not usually reached. However it is possible that the limit
is reached during start-up or during a fresh installation of a
system. In this case, the LED of the accessory lights up red.
It may be non-responsive for a short period (max. 1 hour),
until the time restriction for transmission has expired. After
this period, it will operate normal again.
