Switch on the outdoors sensor for temperature/humidity first, then the rain and wind sensors. Only then
should the batteries be inserted into the weather station and the second display unit.
Only this ensures proper device function.
At first installation, you need to know the altitude of your location for the weather station. It is later used
to determine the corrective value for barometric pressure. The altitude for your position (only an
approximate value is required) can be found e.g. on maps or the website of your city/municipality.
Before firmly installing the rain and wind sensors, test the function of all devices.
The 30 m (rain and wind sensors) and 100m (outdoors sensor for temperature/humidity) radio ranges
are the so-called "free field ranges", i.e. the maximum ranges for direct lines of sight between the
transmitters (sensors) and receivers (weather station or second display unit).
This ideal configuration is, of course, not practicable, because there will be furniture, walls, windows
or plants between the sensors and the weather station (or second display unit.
Another interrupting influence that strongly decreases range is proximity to metal parts, electric/
electronic devices or cables. Reinforced concrete ceilings, medal coated insulating glass windows or
other devices transmitting on the same radio frequency may also cause problems.
Do not put the devices directly next to each other for the function test. Keep a distance of at least 50
cm, or the transmitters may influence each other.
a) Temperature/Humidity Sensor
• Open the battery compartment of the back by removing the four screws (28) of the battery compartment lid (27).
If the rubber sealing sticks to the battery compartment lid, replace it in the respective groove.
• Use the slider (31) for setting the transmission channel if you are operating more than one temperature/humidity
sensor (use one channel per device). If only one temperature/humidity sensor is used, set channel 1 for it (required
for recording function).
• Insert two type AA/mignon batteries with correct polarity into the battery compartment (32) (observe positive/+ and
negative/-). All display segments appear briefly in the display, afterwards the first measuring value for the
temperature and the humidity.

If there is no display, check whether the batteries are charged and were inserted correctly. If required,
briefly press the countersunk reset button with a toothpick (do not exert any force when pressing!) or
remove both batteries and insert them again after a short break.
• Put the battery compartment lid (27) back on properly and screw it tight.
• When selecting the installation site for the temperature/humidity sensor, make sure that it is protected from
precipitation (e.g. beneath an eave). Otherwise, the sensor would no longer measure the air temperature.
The sensor may also not be exposed to direct sunlight, as this would falsify the measuring values.
Using the wall mounting opening (30), the temperature/humidity sensor can be hung to, e.g., a screw.
