After battery/adapter installation, the monitor will enter sea level pressure setting mode directly and the
pressure reading will flash. Press “▲” or “▼” to set the sea level pressure value. Press “PRESSURE” to
confirm the setting and exit. This allows the unit to provide a more accurate weather forecast &
pressure reading.
You can also set the sea level pressure any time after the installation is completed. For more
information, see “WEATHER FORECAST & BAROMETRIC PRESSURE” section.
Note: you may obtain the current sea level pressure from the weather web site for your locate area.
2. Selecting a location for the anemometer
Select a mounting location for the anemometer that is:
-Outdoors, not blocked on top or sides, so wind can freely reach the anemometer
-Within 30 meter open area from the monitor. Reduce distance if obstacles is between the
anemometer & the monitor
The best location for the anemometer is usually mounted on a mast in an open area where wind is not
blocked on top or sides, or above roof level on the building where the monitor is located.
Testing the effective transmission range
Before mounting the anemometer, measure the distance between the monitor & anemometer and be
sure it is within the effective transmission range. It is recommended to perform a simple RF
transmission test before mounting.
1) Place the monitor in your selected indoor location and install adapter & batteries (see “Battery &
adapter installation for the monitor” section above)
2) Place the anemometer horizontally in your selected outdoor location. Loosen the screws on the
battery door with a small Phillips screwdriver and open the battery door. Insert 2 pieces of AA
batteries according to the polarity indicated. Close the battery door and tighten the screws.
3) Hold “CHANNEL/SEARCH” button on the monitor for 3 seconds and the wind direction,
temperature & humidity icons will flash on the display. The monitor is now searching for all remote
sensors for 2 minutes.
4) If valid wind direction, wind speed and channel-1 temperature/humidity readings are shown on the
monitor within 2 minutes, the RF transmission is successful and the anemometer & monitor are
within the effective transmission.
If above readings are not shown after 2 minutes of searching, the transmission is failed.
Shorten the distance between the anemometer & monitor. Reset the anemometer by removing all
batteries from the anemometer & wait for 10 seconds before re-installing the batteries again.
Repeat step 3 & 4 until the transmission is successful.
5) Remove all batteries from the anemometer before mounting and calibration.

NOTE: Whenever the radio-controlled icon is flashing on the display, the weather station is
receiving radio-controlled clock signal and the RF reception for remote sensors will stop temporary for
around 8 minutes. Wait until this icon stops flashing (or disappear) before searching for the remote
sensors again by holding the “CHANNEL/SEARCH” button on the monitor for 3 seconds
3. Mounting the anemometer
Important: Before mounting, be sure the monitor & anemometer are within the effective transmission
range.
Note: To mount the anemometer, you need a mast (not supplied) about 1 – 1.25 inches (2.54 – 3.1 cm)
in diameter, and the hardware necessary to fasten it to the mounting location. If you previously installed
such a mast (for mounting antenna, for example), you can mount the anemometer on that mast.
1. If necessary, mount and ground a mast as directed in the instructions provided by the mast.
2. Place the supplied U-shape metal plates around the mast. Insert 4 pieces of the supplied Hex
screws through the holes of the U-shape plates and the holes on the anemometer’s mounting
bracket.
(The wind vane is above the wind cup and the metal bar of the anemometer is in horizontal level)
3. Tighten the supplied Hex nut onto both ends of each screw
4. Calibrating the anemometer & installing batteries
After mounting the anemometer, follow these steps to calibrate the wind direction so that the
anemometer properly measures the wind direction and transmit to the monitor. Be sure battery has
been removed from the anemometer before the calibration.
Important: The same calibration (step 1 to 5) is needed for the first set up and every battery

replacement.
1. After mounting the anemometer, loosen the screws on the battery door with a small screwdriver and
open the battery door.
2. Use the compass on the anemometer and turn the wind vane so it is pointing due north.
3. Hold the wind vane pointing due north and do not allow it to turn. Insert 2 pieces of AA batteries
according to the polarity indicated. The red LED indicator above the battery cover of the
anemometer will flash few times right after battery installation. Be sure the vane is pointing due
north at the moment when red LED flashes and the calibration is now completed. Replace the
battery cover and tighten the screws.
4. If the wind vane is not pointing due north when the red LED first flashes, remove batteries and
repeat step 2 & 3.
5. Hold “CHANNEL/SEARCH” buttons on the monitor to search for remote transmitter. Wind direction,
wind speed, wind chill & channel-1 temperature/humidity readings will appear within 10 minutes if
the RF transmission is successful.
5. Selecting a location for the rain gauge
Select a mounting location for the rain gauge that is:
-a flat, level surface. Look for a location where the rain gauge can be placed 1 meter or more
above ground level.
-within 30 meter (100 feet) open area from the monitor. Reduce distance if obstacles is between
the rain gauge & the monitor
-in an area not blocked on the top or sides, so rain can freely reach the rain gauge (for example,
not under an overhang or too close to a building or fence)

5
Cautions:
-To prevent false rainfall readings caused by water splashes, do not choose a location that is not
level or that is too close to the ground, a swimming pool, lawn sprinklers, or anywhere water might
accumulate or run off
-The screen in the cylinder of the rain gauge filters most debris (such as leaves) that might fall into
the rain gauge. To avoid frequent build-up of debris in the cylinder, do not mount the rain gauge
too close to the trees or plants
6. Battery Installation for the rain gauge
1. Press the tabs back as indicated below to unlock the rain gauge cover
2. Lift the rain gauge cover off its base. Then carefully remove the packing tape from the bucket
assembly
3. Open battery cover and insert 2 pieces of AAbatteries according to the polarity indicated. Close the
battery cover
4. Replace & lock the rain gauge cover on the base
5. Hold “CHANNEL/SEARCH” button on the monitor for 3 seconds and the total rainfall “- - - -“ will
flash. The monitor is now searching for all remote sensors for 2 minutes. Total rainfall reading (in
this case “0” mm or inch) will appear within 2 minutes if the RF transmission is successful and the
monitor & rain gauge are now within the effective transmission range.
6. If total rainfall “- - - - “ stop flashing and stay on the display after 2 minutes of searching, the RF
transmission is failed. Shorten the distance between the monitor & rain gauge. Reset the rain
gauge by removing all batteries from the rain gauge and wait for 10 seconds before re-installing the
batteries again. Then repeat step 5 (& 6) until the RF communication is completed.
NOTE: Whenever the radio-controlled icon is flashing on the display, the weather station is
receiving radio-controlled clock signal and the RF reception for remote sensors will stop temporary for
around 8 minutes. Wait until this icon stops flashing (or disappear) before searching for the remote
sensors again by holding the “CHANNEL/SEARCH” button on the monitor for 3 seconds.

6
7. Mounting the rain gauge
Before mounting the rain gauge, be sure the rain gauge & monitor are within the transmission effective
range and batteries are installed.
1. Hold the base of the rain gauge flat against the mounting surface then use a level to make sure the
rain gauge (as it rest on the mounting surface) is horizontally level.
2. Use a pencil to trace the inside of the mounting holes on the base of the rain gauge to mark the
screw locations.
3. Drill a hole in the center of each marked location and insert the supplied plastic screw plugs
4. Hold the rain gauge against the mounting surface so the holes on the base are aligned with the
plugs, then thread the supplied washer head screws into each hole and use a screwdriver to tighten
them.
8. Installing additional remote thermo-hygrometer sensor(s)
Additional remote thermo-hygrometer sensors can be purchased separately (not supplied in the
package).
1. Select a location for the remote thermo-hygrometer that is within the effective transmission range of
50 meters (164 feet). Shorten the distance if obstacle is between the monitor & remote sensor.
2. Use a small screwdriver to loosen the screws on the battery door of the remote sensor. Insert 2
pieces of AAA batteries according to the polarity indicated.
3. Assign channel 2 or 3 to the remote sensor by setting the slide switch inside the battery
compartment. (Channel 1 is used by the anemometer and should not be assigned to the new
remote thermo-hygrometer)
4. Press “Tx” button inside the battery compartment of the remote sensor to transmit temperature &
humidity data to the monitor. Then close the battery door and tighten the screws.

IMPORTANT NOTE:
Warning! The weather station and the outside sensor contain sensitive electronic components. Radio
waves transmitted e.g. from mobile telephones, walkie talkies, radios, WiFi, remote controls or
microwaves may influence the transmission distance of the weather station and the outside sensor and
lead to a shorter reception range. It is therefore important to keep as great distance as possible
between the devices of the weather station and the outside sensor and the devices which send out

15
radio waves. We do not guarantee the maximum specified transmission range between the weather
station and the outside sensors due to the radio frequency interference in the environment.

„WETTERVORHERSAGE & BAROMETERDRUCK“ für weitere Informationen.
Beachten Sie: Den aktuellen Meeresspiegeldruck können Sie bei nationalen Wetterdiensten erfahren.
2. Standort für den Windmesser auswählen
Der Windmesser sollte angebracht werden:
-draußen mit ausreichend Platz nach allen Seiten, damit der Wind den Windmesser ungestört
erreichen kann.
-in offener Landschaft höchstens 30 Meter vom Bildschirm entfernt. Der Abstand sollte geringer
sein, wenn sich Hindernisse für das Signal zwischen dem Windmesser und dem Bildschirm
befinden.
Der beste Standort für den Windmesser ist in der Regel in offener Landschaft, wo der Wind
ungehinderten Zugang von allen Seiten hat, oder auf der Spitze des Gebäudes, in dem sich der
Bildschirm befindet.
Test der Signalstärke
Vor der Montage des Windmessers sollte der Abstand zwischen dem Windmesser und dem Bildschirm
ausgemessen werden, und außerdem gewährleistet sein, dass das Signal deutlich empfangen werden
kann. Es wird empfohlen, den folgenden Signaltest vor der Montage durchzuführen:
1. Platzieren Sie den Bildschirm am ausgewählten Ort (in einem Gebäude), legen Sie die Batterien
ein und schließen Sie das Gerät an die Stromversorgung an (siehe Abschnitt oben ”Einlegen der
Batterien und Stromversorgung des Bildschirms“).
2. Platzieren Sie den Windmesser waagerecht am ausgewählten Ort (draußen). Lösen Sie die
Schrauben des Batteriefachdeckels mit einem kleinen Philips-Schraubenzieher und öffnen Sie den
Deckel. Setzen Sie 2 AA-Batterien wie im Piktogramm angegeben ein. Schließen Sie den Deckel und
ziehen Sie die Schrauben an.
3. Drücken Sie den “CHANNEL/SEARCH”-Knopf auf dem Bildschirm und halten Sie ihn drei
Sekunden lang gedrückt, damit das Symbol für die Windrichtung, die Temperatur und die

19
Luftfeuchtigkeit erscheint. Das Bildschirmmodul sucht nun innerhalb von 2 Minuten nach Signalen von
allen Sensoren in der Umgebung.
4. Werden die aktuelle Windrichtung, Windgeschwindigkeit, Temperatur und Luftfeuchtigkeit für
Kanal 1 innerhalb von 2 Minuten auf dem Bildschirm angezeigt, wird das Signal deutlich empfangen
und der Abstand zwischen den beiden Einheiten ist in Ordnung.
Werden die oben genannten Daten nicht innerhalb von 2 Minuten angezeigt, hat die Übertragung
nicht funktioniert. Verkürzen Sie den Abstand zwischen dem Windmesser und dem Bildschirm und
setzen Sie die Einstellungen des Windmessers zurück, indem Sie die Batterien des Windmessers
entfernen und 10 Sekunden warten, bevor Sie die Batterien wieder einsetzen. Wiederholen Sie
Schritt 3 und 4, bis die Übertragung gelingt.
5. Entfernen Sie vor der Installation oder Justierung immer alle Batterien aus dem Windmesser.
Beachten Sie: Wenn das Radiosignal in der Anzeige blinkt, empfängt die Wetterstation das Signal
vom DCF77-Sender in Frankfurt. Die RF-Verbindung der Regenmesser, Windmesser und eventuell des
Thermo-Hygrometers stoppt mit dem Empfang des Signals innerhalb von 8 Minuten. Warten Sie mit der
Suche nach dem Signal für Ihre Sensoren (indem Sie ”channel/search” drücken), bis das
ferngesteuerte Signal aufgehört hat zu blinken.
3. Montage des Windmessers
Wichtig: Vor der Montage sollte gewährleistet sein, dass das Signal zwischen Bildschirm und
Windmesser deutlich empfangen wird.
Beachten Sie: Zur Montage des Windmessers benötigen Sie einen Mast (nicht im Lieferumfang
enthalten) mit zirka 2,5 – 3,1 Durchmesser plus Zubehör, um ihn an der ausgewählten Stelle
anzubringen. Haben Sie früher einen vergleichbaren Mast (beispielsweise bei der Montage einer
Antenne) errichtet, kann der Windmesser an diesem Mast angebracht werden.
1. Bauen Sie, falls erforderlich, einen Mast nach Anweisung auf.
2. Platzieren Sie die mitgelieferten U-förmigen Metallplatten am Mast. Setzen Sie die 4
mitgelieferten Schrauben in die Löcher der U-förmigen Platten ein und setzen Sie dann die
Löcher am Montagestück des Windmessers an.
3. (Die Mühle sollte sich über dem Windloch befinden und der Windmesser waagerecht sein).
4. Ziehen Sie die mitgelieferten Muttern an beiden Enden der Schraube fest an.
