In normal cases, the radio connection between the receiver and the
transmitter has a range of at least 100 meters in free field, inasmuch as
it is not obstructed by obstacles like buildings, trees, power lines, etc.
Interference signals emitted by PC monitors, radios or TVs, for exam-
ple, may prevent the establishment of the radio connection alltogether.
Observe this when selecting the installation sites!
8. After inserting the batteries into the outdoor sensor, you should also insert the
batteries in the basis devices to ensure a quick signal reception. If the batteries
are first inserted in the basis 5 hours after inserting them in the outdoor sensor, a
successful signal reception for the outdoor sensor is no longer possible. In this
case, the batteries have to be removed and reinserted again. (Repeat the proce-
dure starting at point 1).
If the signal is received correctly, the symbol is permanently displayed. If the signal is
not displayed, the radio connection is impaired. In this case, you have to look for a
new installation site for the transmitter or the basis.
Replacing the batteries
The basis works with three
1.5 V mignon cells.
A battery change is neces-
sary when the display shows
the low battery symbol on
the top left.

Sensor reception signal
After the batteries were inser-
ted in the correct sequence,
the synchronisation phase bet-
ween the basis station and the
transmitter starts. The sensor
reception signal blinks during
this time.
1. Remove the battery compartment
cover.
2. Insert the batteries observing the
correct polarity (see marking in
the battery compartment).
3. Replace the cover.
