5. Make sure that the base unit and the radio sensor are
set to the same channel.
When changing the batteries, always remove the batteries
from both the base unit and the sensor and reinsert them in
the correct order so that the radio link can be re-estab-
lished. If one of the two devices is operated via a mains
power connection, the power connection must also be
briefly disconnected for this device when the batteries are
changed. If, for example, only the batteries in the sensor
are replaced, the signal may subsequently not be received
at all or not be received correctly.
Note that the actual range depends on the respective con-
struction materials used for the buildings as well as the re-
spective position of the base unit and the outdoor sensor.
External influences (various radio transmitters and other
sources of interference) can greatly reduce the possible
range. In such cases, we recommend finding other locations
for both the base unit and the outdoor sensor. Sometimes
moving the sensor by just a few centimeters is enough!
7 Battery level indicator
1. When the level of the batteries in the base station or in
the wireless sensor reaches a critical level, the battery
level symbol appears in the appropriate area on the
display.
2. When replacing one set of batteries, always remove the
batteries from the other part of the unit and reinsert
them in the correct order (see chapter "Setting up
power supply"). Replace the batteries to be changed in
the corresponding part of the device with a completely
new set with full capacity. This ensures that the connec-
tion between the devices will be reestablished again
correctly.
