HumanTechnik lisa DS-2/RG Mode D'emploi page 13

12 / 24 hour mode
The time can be displayed in a 12- or
24 hour mode.
The adjustment is made with the
»24h/12h« switch on the reverse side
of the alarm clock.
Power cut backup
The battery compartment can hold 4
batteries of size AAA (not included).
In the event of a power cut, these
guarantee the continuation of the set
time and the display of the lisa sig-
nals.
Please note: During a power cut, the
time display and the flash are not ac-
tive as the power consumption is too
high for the backup batteries!
lisa receiver functions:
The alarm clock is equipped with all
functions of a lisa RF receiver.
Setting the correct radio channel
A special digital transmission pro-
cess ensures that the radio signals
are received error-free. This process
also makes it possible to set 10 dif-
ferent radio channels. When supplied
from the factory, the »lisa DS-2/RF« is
set to channel 0. It is only necessary to
set units to other channels if you have
several different users operating units
in the same building. Set the channel
you want by adjusting the channel
selector switch on the underside of
the unit to the required channel num-
ber. Use a small screwdriver to adjust
this switch. All transmitters and recei-
vers within your system must be set to
the same channel.

Recalling the most recent signal
The »lisa DS-2/RF« stores each
signal it receives for a period of 3
minutes.
During this time, you can call up the
signal again by pressing the Light/
Snooze lisa signal cancel switch but-
ton. The signal is then displayed on
the indicator LEDs. A flash signal is
not triggered.
