Baby cry transmitter operation
The baby cry transmitter contains a
built-in microphone to pick-up the
sound of a crying baby. Plug the
transmitter into a convenient mains
socket near to the baby.
On the underside of the transmitter
are two knobs.
The knob labelled S adjusts the
microphone sensitivity.
The knob labelled T adjusts the
length of time the sound must be on
before the transmitter activates.
Knob T in position 0 (fully anti-
clockwise) = minimum respond time
(approx. 0.2 sec.)
Knob T in position 3 (fully clockwise) =
maximum respond time ( approx. 3 sec.)
Knob S in position 0 (fully anti-clock-
wise) = minimum microphone sensitivity
Knob S in position 3 (fully clockwise) =
maximum microphone sensitivity.
An initial setting with high microphone
sensitivity and average response time
(approx. 2.5 sec.) is recommended.
Knob S = 3 (fully clockwise)
Knob T = 1.5 (half way round)
With this setting the transmitter does
not react to short loud sounds, but
reacts to sounds with a constant
sound level that are uninterrupted for
approx. 2.5 seconds (e.g. baby cry).
However, you will need to experiment
with these settings to find the most
convenient settings.

Additional 4-metre lead microphone
(accessory):
Simply plug the microphone cable
into the socket on the underside of
the baby cry transmitter. The micro-
phone can now be placed very near
to the baby if the built-in microphone
is too far from the baby to pick up the
sound adequately.
Warning
The additional microphone and lead
could prove a danger to a baby or
small child. Ensure that they are well
out of reach.
Important note
All lisa devices connected to the
mains supply have a low power con-
sumption which may lead to the devi-
ce feeling warm. This is normal and
does not interfere with the normal
function of the devices. These signal-
ling 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 devices
have an integrated electronic control-
ler which may stop working after
these conditions. If this happens sim-
ply unplug each of the devices and
plug them in again.
