Position within reach of an outlet that is always active. Some outlets in living rooms and in
bedrooms may only be active when the light switch is on.
This station must operate with the 5 volt power cord in order to receive sensor updates
and/or to update Wi-Fi data when connected. Operation on battery power will only maintain
time/date settings if you need to move your station.
Best reception occurs when only one wall is between your station and each sensor outside.
Position you station six feet from other electronics and wireless devices. If you suspect RF
(radio frequency) interference, simply move your weather station a few feet.

WHAT IS DISTANCE | RESISTANCE | INTERFERENCE?

Distance:
The maximum transmitting range in open air is over 400 feet (121.92 meters) between each
sensor and your station.
Consider the signal path from your station to each sensor as a straight line.
Consider the distance the station is from other electronics in the home.
Resistance:
Each obstacle: walls, windows, vegetation, stucco, concrete, and large metal objects will
reduce the effective signal range by about one-half.
Mounting your sensors on a metal fence can significantly reduce the effective signal range.
Interference:
Consider electronics in the signal path between the sensors and your station.
Simple relocation of the sensors or the station may correct an interference issue.
Windows can reflect the radio signal.
Metal will absorb the RF (radio frequency) signal.
Stucco held to the wall by a metal mesh will cause interference.
Transmitting antennas from: ham radios, emergency dispatch centers, airports, military
bases, etc. may cause interference.
Electrical wires, utilities, cables, etc. may create interference if too close.

READINGS: HOW DO I INTERPRET THE CURRENT WIND READINGS?

Wind Speed - is the highest current wind speed at the last record.
Top Speed – is the highest wind speed reading in the past hour.
Standalone station: When not connected you will see the 24HR wind speed next to the
1HR wind speed.
Connected Station: When station is synced to the La Crosse View™ App, the 24HR wind speed
will forecast NWS Wind Direction.
