2. Setting the correct radio channel
Thanks to a special digital transmis-
sion process the radio signals can
be smoothly recognised. This proce-
dure enables 10 different radio
channels to be set. The default set-
ting on all units is channel 0. The
units only need to be set to different
radio channels if units are being
operated by several users within the
same building.
Open the housing as described
under the "Inserting the battery"
section. You can set the radio chan-
nel desired using three small short
circuit bridges.

Please note
All transmitters and receivers must
be set to the same channel.
Triggering the person call sig-
nal/door bell signal
By pressing the person call button/
door push button a signal is trigge-
red on each receiver set to the same
channel as the transmitter.
Radio range
The transmitter is designed to have
a radio signal range of 80 meters
under optimum conditions.
The following conditions may result
in a reduced range:
- Signal transmission through buil-
ding structures or vegetation
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
may prevent the receiver from
functioning at all.
- Positioning of the transmitter at an
unfavourable distance from surfa-
ces which reflect radio waves, for
example floors and walls. This may
lead to the signal wave being wea-
kened or even cancelled out by the
reflected wave.
