the transmitter. Lay the cable to
the door chime and attach the
microphone to the door chime by
peeling off the paper circle to reve-
al the sticky ring beneath.
For optimal operation of the trans-
mitter the sensitivity may be adju-
sted so that only the doorbell acti-
vates the transmitter and not bak-
kground noise.
Setting the sensitivity
1. Set the sensitivity controller to
its lowest level (turn to the anti-
clockwise to stop)
2. Activate the doorbell and gradu-
ally increase the sensitivity of the
transmitter (by turning the dial
clockwise) until the transmitter
reacts to the doorbell.
3. If your intercom system opera-
tes with different signal tones,
make sure that both signal tones
are reliably detected.
Telephone connection
Plug the transmitter into a conve-
nient mains socket. Plug the end
of the cable with the transparent
clip-in connector (6-pin plug) into
the socket at the underside of the
transmitter. Plug the other end into
the telephone socket.
If the required telephone socket is
in use plug a 3-way telephone
adaptor into the socket and plug
your telephone into one of the
sockets on the adaptor.
Warning
Only use the supplied telephone
cable otherwise correct operation
can not be guaranteed. The lisa
Combi II is only designed for con-
nection to analogue systems. If a
connection is required to a digital
system (e.g. ISDN or part of a PBX
exchange system) please use a
Telephone Transmitter- Acoustic or
the Universal lisa.
Important note
All lisa devices connected to the
mains supply have a low power
consumption which may lead to
the device feeling warm. This is
normal and does not interfere with
the normal function of the devices.
These signalling systems have a
high operational safety. Should any
faults occur in spite of proper
installation and use, please contact
your dealer.
High and low voltage spikes (e.g.
during a thunderstorm) can occur
on the mains supply. The lisa devi-
ces have an integrated electronic
controller which may stop working
after these conditions. If this hap-
pens simply unplug each of the
devices and plug them in again.
As a precaution remove all devi-
ces from their sockets during a
thunderstorm.
The use of halogen lamps of or
other equipment (e.g. Microwave
