ASSEMBLY
With a flashlight, look into the mounting hole that will receive the anemometer axle shaft, on the
back of the wind cups. Check that the set screw is backed off appropriately, not obstructing the
opening.
Place the wind cups over the axle shaft protruding from the anemometer housing and gently slide
into place.
Insert the Allen wrench tool provided into the wind cups opening and tighten the small set screw
i
nside.
Test to assure the wind cups are securely mounted on the anemometer shaft and spin freely
BATTERY INSTALLATION
Remove four (4) screws from the battery compartment with a small Phillips screwdriver.
Open the battery compartment and install 2 “AA batteries (not included) matching the polarities
shown.
Replace the battery compartment door and secure the screws.
A
LIGNING
Point the wind direction vane to the North (use a compass or map if necessary).
Press “SET” opening located inside battery compartment with a paper clip or similar tool. This will
“SET” the local wind direction to North. Continued pressing of “SET” alternately toggles wind
direction between the factory default preset or user set direction.
NOTE
: Repeat this procedure every time after whenever changing the batteries.
MOUNTING
Securely mount the anemometer base to an appropriate vertical surface, using the fittings provided.
PLACEMENT TIPS:
The anemometer should be mounted in an open area with unobstructed air flow; away from the
nearby trees, buildings or other structures.
Aim for a maximum exposure of the anemometer to the most common wind directions in the area.
The suggested mounting height for the anemometer is 33 feet (10meters) above the ground.
MAIN UNIT
The main unit should be placed indoors. It measures: pressure, indoor temperature, humidity, and
receives the US Atomic Clock data and data from each of the remote weather sensors.

Display
Light sensor detects low light conditions and LCD lights up automatically when adapter is
connected
Power
7.5 V AC/DC adapter for automatic remote control
4 “AA batteries
BATTERY INSTALLATION
Open the battery compartment door on the back of the main unit.
Insert 4 “AA batteries according to the polarities shown and replace the battery compartment
door.
Connect 7.5 V AC/DC adapter provided to the main display unit and plug into to the wall power
outlet.
NOTE
: The AC/DC adaptor connection is required for automatic backlight control function. When the
main unit operates on battery power alone, the auto backlight control function is disabled.
Connect the table stand to the back of main unit when placing on a table or other horizontal
surface.
When mounting the main unit on the wall or vertical surface, detach the table stand and use the
mounting hardware provided.
Placement tips
Make sure that the main unit is locating within the operating range of all remote weather sensors.
Ideally the remote weather sensors should be mounted within the line-of-sight of the main unit.
Transmission range may be affected by trees, metal structures and electronic appliances.
Test reception before permanently mounting all the remote weather sensors.
A
void placing the main unit in the following areas:
Direct sunlight and surfaces emitting and radiating heat, such as heating ducts or air conditioners.
Areas with interference from the wireless devices (such as cordless phones, radio headsets, baby
listening devices) and electronic appliances.
OPERATION
Once the main unit is powered, the display will show all available LCD segments for a moment.
IMPORTANT: All of the display functions will be locked, allowing setting your local altitude or sea level
pressure parameters.
The locked display will show the pressure and weather forecast icon and abbreviation “hPa/
mBar” flashing, indoor temperature and humidity readings and default time “12:00pm”.
