BATTERIES: WHAT DO I NEED TO KNOW ABOUT BATTERIES?
•Your Station comes with a CR2032 battery installed to preserve Time and History Records in
the event of a power failure. The 5 Volt Power Cord is required to operate this station.
•Your LTV-WSDTH03 OR LTV-WSDTH04 Wind/TH sensor requires 3 “AA” batteries. This
along with the solar panel extends sensor life up to 3 years.
HARDWARE: SENSORS AND STATION
Your V50-C78861 station comes with:
LTV-WSDTH03 OR LTV-WSDTH04 Sensor with Wind Speed, Wind Direction, Temperature
and Humidity
WHAT ARE THE POWER REQUIREMENTS FOR THIS STATION?
LTV-WSDTH03 OR LTV-WSDTH04: 3 “AA” batteries
V50-C78861:5 volt power cord (required) and CR2032 batteries for backup of your time and
date. Battery operation only will not update sensor or Wi-Fi data. Power cord is required.
SETUP AND MOUNTING
SETUP: HOW DO I SETUP MY STATION?
Your station is a fully functional standalone station.
1. Remove the Isolation Tab from the LTV-WSDTH03 OR LTV-WSDTH04 sensor and turn the
switch to ON.
2. Install 5 volt power cord into outlet, and into the station. Remove the insulation tab from the
CR2032 battery in your station.
3. Let sensor and station sit within 10 feet of each other for several minutes to lock the sensor
signal to the display.
Once the sensor is connected, you can choose to connect to the La Crosse View™ app or
continue to use as a standalone station. You can always connect later if you choose.
MOUNTING: WHERE DO I MOUNT/POSITION MY SENSORS?
LTV-WSDTH03 OR LTV-WSDTH04:
•Place your wind sensor two times higher than any large object within 50 feet. Wind does not
pass through hard objects, it is distorted by them. If your sensor is too close you will
measure the air turbulence and not actual wind speed.
•Place away from trees. Wind passing through trees moves slower than wind in open areas.
•Mount your sensor in a vertical position with the wind cups on top.
•Maximum transmission distance from your multi-sensor to your station, in open air is 400 feet
(121.92meters).

5 | Page
•Use the included mounting bracket or your own mounting pole (no more than 1 inch outer
diameter to fit). Secure to the sensor with screws provided. Tighten the screws to snug (do
not over tighten).
•Solar panel must face South to provide correct Wind Direction.
•General Wind Sensor mounting video: http://bit.ly/wind_sensor_mounting
WHERE TO I PLACE MY STATION?
Your station is designed for flexible placement on a desk or countertop, or to position on the
wall. When the stand is closed, it provides wall mounting holes.
•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.

speed history at 24 hours, 7 days, current month, and current year.
Press and release the WIND button to toggle through the Wind Speed History times.
•1 Hour Top Speed- Updates each hour and shows the highest wind speed in the past 60
minutes.
•24 Hour Wind Speed – Shows the top speed in the past 24 hours from the last record. This
is a rolling 24 hour period and not a set midnight to midnight reading. This means it updates
each hour to show you the past 24 hours.
•7 Days - Shows the top speed in the past 7 days from the last record. This is a rolling 7 day
period, not a Monday through Sunday record. Updates at midnight each day.
•Month – Shows top wind speed for the current month. Record is from the first day of the
month to the last day of the month. When in the middle of the month, it will show the
readings from the first day of the month to the last full day. Example: If today is the 15th of
the month, the top speed is from the 1st to the 14th. After midnight, the 15th will be included.
Note: Press and release the PLUS (+) button to view up to 11 previous months or history.
