Important notice:
When teaching a sound, please avoid
any other environmental noise.
The soundmonitor should remain in
the position in which the according
sound was recorded, in order to as-
sist a secure recognition of the sound
when it occurs again.
Please note:
This device can only recognise re-
peatable and unaltering electronic
sounds. A mechanical sound source
or voice cannot be identified.
3. Power supply
Connect the power supply with the ac-
cording socket on the underside of the
»soundmonitor«.
Plug the power supply unit into a regu-
lar 230V mains electricity outlet.
Blackout-Backup

wer cuts.
The standby provided by the batteries
covers approx. 16 hours.

4. Setting the correct radio channel
A special digital transmission process
ensures that the radio signals are pi-
cked up without errors. This process
also makes it possible to set 10 diffe-
rent radio channels.
The »soundmonitor« is set to channel
0 by default.
It is only necessary to set units to
other channels if you have several
different users operating »lisa RF«
systems in the same building.
Set the required channel by using a
small screwdriver to turn the channel
selector switch, which is located on
the underside of the device, to the re-
quired channel number.
All transmitters and receivers must be
set to the same channel.
