Occasionally adding a new wireless electronic device to the home will cross the signal path
for the sensor. If this occurs try moving your station a few feet or turning the station 90
degrees for a better angle to receive the sensor signal.
When you have good batteries, and good location, hold the SENSOR button for three
seconds to search for your sensors. If you regain connection while the sensor is mounted,
great. If you do not regain connection, bring the sensor within 10 feet of the station and
search again.

WIND INTERMITTANT: WHY DO MY WIND READINGS COME AND GO?

RF (radio frequency) communication may come and go occasionally. This can be normal in
some environments (e.g. moister climates).
If a sensor goes out, please wait 2-4 hours for it to reconnect on its own. Please be patient
– these stations can reconnect on, after many hours out.
RF (radio frequency) communication is not always 100% on. Certain temporary conditions
can cause it to go out for a time (e.g. 100% humidity).
If a miss happens:
If your wind sensor loses connection to the station for any reason, the station will show
dashes after 30 minutes.
The station will search for 5 minutes every hour to reconnect with wind sensor.
Be sure you have good batteries. Manually search for your sensor.
Try this:
Bring your wind sensor within 10 feet of your station and make sure it is connected to the
station.
After 15 minutes move the wind sensor into the next room with a wall between the sensor
and the station for 1 hour.
If there is no loss of signal in that hour, move the wind sensor just outside.
Continue moving the wind sensor back to its original location.
If you lose connection, look for sources of

WIND ACCURACY: WHY IS MY WIND SPEED INACCURATE?

What are you comparing your wind speed to? Your local reporting station is miles from your
location and should not be used for comparison.
Check the unit of measure (MPH, or KMH).
Check to see if your station receives the same repetitive wind speed recording from the
sensor multiple times.
Check that the cups turn freely.
Check for obstructions that prevent clear wind flow to the cups.
Check mounting. In most cases, the wind sensor needs to be 6 feet or more above the
highest point on the roof in order to clear nearby obstructions and read accurately. A 50-foot
clearance in all directions is best.
It is helpful to send pictures of the sensor mounting, if you need to contact customer support.
