tablished. If one of the two devices is operated via a mains
power connection, the power connection for this device
must also be disconnected briefly when changing the bat-
tery. If, for example, only the batteries in the sensor are re-
placed, the signal cannot be received or can no longer be
received correctly.
Note that the actual range depends on the building materi-
als used in the building and the position of the base unit and
outdoor sensor. External influences (various radio transmit-
ters 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 a shift of just a few centimetres is
enough!
Though the remote unit is weather proof, it should be placed
away from direct sunlight, rain or snow.
