and operation
The assembly, electrical connection and
the settings in the device as well as the
commissioning must be carried out only

Check the site of installation before
fitting the unit with regard to possible
radio interference by electrical
equipment or building influences which
may affect the functioning. If the radio
signal route is compromised then an
alternative installation site must be
chosen.
