Battery operation
If the radio doorbell transmitter is to be operated with batteries, insert them
according to the polarity markings in the battery compartment.
Caution: If the radio doorbell transmitter is operated via an external power
supply, no batteries may be inserted!
Note: In battery operation, the nameplate illumination is not active as this
would discharge the batteries very quickly.
Closing the housing
Insert the silicone seal with the nameplate(s) into the front casing and place both
together on the assembled rear casing. Screw both enclosure parts together
with the enclosure screws.
Note: You should only close the housing after the receiver(s) has/have been
tuned in and the desired melody has been set.
