Advice on planning
Before installation, conduct a local inspec-
tion, so that you can plan the best possible
installation. Answer the question: What must
/ should be installed where?
Then, try to find any possible interference
sources and assess the transmission reliabil-
ity. (for more on this, see the „Background
Information“ section)
Perform a radio test under practical condi-
tions. (open/closed windows/doors; switch
electrical consumers on/o; etc. …)
Only conclude the desired installation once
the radio test has been successfully conclud-
ed.
Note that Free-control radio receivers cannot
be used in conjunction with common switch-
es/buttons.
