2. Setting the correct radio channel
A special digital transmission process
ensures that the radio signals are
picked up without errors. This process
also makes it possible to set 10 diffe-
rent radio channels.
When supplied from the factory, all RF
lisa combi II are set to channel 0. It is
only necessary to set units to other chan-
nels if you have several different users
operating units in the same building.
Set the required channel by using a
small screwdriver to turn the channel
selector switch, which is located
towards the top of the battery compart-
ment, to the required channel number.
All transmitters and receivers must be
set to the same channel.
Fig. Setting the correct radio channel.
3a. Installing the telephone cable
Plug the end of the cable with the
transparent clip-in connector (6-pin
plug) into the socket on the undersi-
de of the RF lisa combi II transmitter.
Plug the other end into a space tele-
phone socket.
Important
Please only use the telephone cable
supplied with the unit, otherwise pro-
per function cannot be guaranteed.
10 English
The RF lisa combi II is designed to
be connected to an analog telepho-
ne system.
Use the RF telephone transmitter
acoustic if your phone system is
ISDN or part of a PBX (exchange)
system.
3b. Installing the microphone cable
Plug the microphone cable into the
socket on the underside of the RF
lisa combi II. Use the adhesive ring

the acoustic output cover of your
doorbell/intercom system. To do this,
pull off the backing foil from the
adhesive ring on the microphone.
For optimum function of the transmit-
ter, its sensitivity dial switch must be
set so the transmitter reliably res-
ponds to the doorbell.
