Operating principle
A signalling system consists of at
least one transmitter and one recei-
ver. The RF doorbell transmitter direct
picks up the ringing signals from
your doorbell through an electrical
connection. It converts these signals
into radio pulses (868.35 MHz) and
transmits them to the receiver without
the need for wires.
Special features
When a signal is detected, it is trans-
mitted for a total of 22 se conds. This
increases both the reliability and the
range of the system.
Setting up the system –
1. Inserting the battery
There is a battery compartment on
the back of the RF doorbell transmit-
ter direct . Open it by sliding the
cover of the battery compartment to
the right of the receiver using your
thumb. Connect a 9 V block battery
to the connector plug, insert the bat-
tery into the battery compartment
and close the device. When the bat-
tery is connected, the receiving sig-
nals may be triggered once.
