GETTING STARTED
SET UP REMOTE WIND SENSOR
The wind sensor can take 3 readings:
• The wind speed and directions
• The outdoor temperature (Channel 1 only)
• The outdoor relative humidity (Channel 1 only)
The sensor is battery operated and is capable of transmitting data to the base station wirelessly within an approximate operating range of 100 meters (328 feet).
NOTE For best results, ensure that the wind direction indicator on the wind sensor points to the North to enable an accurate reading. The sensor also should be positioned in an open area away from trees or other obstructions.
To set up the wind sensor main body:
1. Assemble the wind direction pointer on the top of the wind sensor.
2. Use the screw (Type B) to fi x.
3. Assemble the wind vanes on the top of the wind pointer.
4. Use the screw (Type B) to fi x.

5. Hold the wind sensor upright and rotate the protective sleeve to the left to unlock.
6. Slide the sleeve down to open the battery compartment.
7. Insert batteries (4 x UM-3 / AA) in the compartment, matching the polarity (+ / -)
and press RESET.
8. Slide the protective sleeve up to close the compartment.
9. Rotate the sleeve to the right to lock.

4. Insert the screw into the plastic base and pole and secure using the Type B screw and washers.
5. Align the back of the plastic base to an existing pole.
6. Using the 2 U-bolts, secure the plastic base to the pole by inserting the ends of the U-bolts into the holes on the plastic base and securing it with washers and bolts.
7. Slide Integrated wind sensor into the plastic base and pole.
8. Insert and screw the Type “X” bolt into the hole.

For continuous use, please install the AC adapter. The batteries are for back-up use only.
NOTE Please make sure the socket-outlet is installed near the equipment and is easily accessible.
SET UP REMOTE RAIN GAUGE
The rain gauge collects rain and takes readings of the total rainfall over a period of time. The sensor can remotely transmit data to the base station.
The base station and rain gauge should be positioned within effective range: about
100 meters (328 feet) in an open area.
The rain gauge should be mounted horizontally about 1 meter (2-3 feet) from the ground in an open area away from trees or other obstructions to allow rain to fall naturally for an accurate reading.
To set up the sensor:
1. Remove screws and slide the cover up and insert the batteries (2 x UM-3 / AA), matching the polarity (+ / -). Press RESET after each battery change.
2. Remove the tape.
RESET
Install the base station batteries (4 x UM-3 / AA) matching the polarity + and -. Press
RESET after each battery change.
NOTE Do not use rechargeable batteries. It is recommended that you use alkaline batteries with this product for longer performance.
The battery icon indicator may appear in the following areas:

BASE STATION
CHANGE DISPLAY / SETTING
To change the display and settings, use the following buttons: SELECT, MIN/MAX,
MODE and ALARM. In addition, the UNIT and SEARCH buttons located at the back of the base station allows pre-setting of the remote sensor channels and the measurement units for display.
TIP To exit from the setting mode, push any button. Alternatively, the base station will automatically exit after 30 seconds.
3. Put a few drops of water on the cross at the base of the funnel to check the horizontal level. Water will pool to the center of the cross when the rain gauge is level.
CLOCK RECEPTION
This product is designed to synchronize its calendar clock automatically once it is brought within range of a radio signal:
WMR90A:
• WWVB-60 generated from the atomic clock in Fort Collins, Colorado. The radio signal range is 3219 km (2000 miles).

Press RESET whenever you change the selected setting.
The reception icon will blink when it is searching for a signal. If the radio signal is weak it can take up to 24 hours to get a valid signal reception.
4 indicates the status of the clock reception signal.
If water remains on 1-4, the gauge is not horizontal.
4. If necessary, adjust the level using the screw.
NOTE For best results, ensure the base is horizontal to allow maximum drainage of any collected rain.
