Install wind vane
Push the wind vane onto the shaft on the opposite side of the wind cups, until it goes no further,
as shown on the left side in Figure 6. Next, tighten the set screw, with a Philips screwdriver, as
shown on the right side, until the wind vane cannot be removed from the axle. Make sure the
wind vane can rotate freely. The wind vane's movement has a small amount of friction, which
is helpful in providing steady wind direction measurements.

Open the battery compartment with a screwdriver and insert 2 AA batteries in the battery com-
partment. The LED indicator on the back of the sensor package will turn on for four seconds and
then flash once every 48 seconds indicating sensor data transmission(the sensor transmission
update period).
