BATTERIES

La Crosse Technology, Ltd. Page 2
•Half of all warranty issues can be resolved with fresh batteries of the appropriate
voltage.
•We suggest name brand alkaline batteries.
•Use batteries dated six years in advance of the current year. Batteries dated earlier
than six years from now may still work, but may be unstable in performance.
•Alkaline batteries manufactured this year will have an expiration date 10 years in the
future. Battery technology has improved and batteries will maintain voltage longer in
storage. However, the environment the batteries reside in for the 10 years can deplete
the power.
•Good name brand alkaline batteries make less noise, which reduces the chance of RF
(radio frequency) interference from the battery compartment. A minimum voltage of
1.48V for each battery is necessary for proper performance.
WEATHER STATION FACTORY RESTART
The factory reset will return your weather station to its default settings. This will clear all
previous recorded history, so you may want to write down data before taking this step.
•Basically, this is a great way to return your station to “out of the box” condition.
•This is more effective than removing all power for clearing out the station.
•All history records will be removed, so write down anything you want to keep.
To factory rest your station:
1. Bring your sensor in, and place 5-10 feet from your station.
2. Remove power from station and sensor for 15 minutes.
3. With power removed press any button 20 times.
4. Insert batteries into sensor and station.
5. Allow 15 minutes for them to connect several times.
6. Place sensor back outside.
BATTERY CHANGE
•After changing batteries in the sensor, hold the + (PLUS) button for 5 seconds to search
for the sensor.
•If this fails to connect the sensor to the station, bring the sensor about five feet from the
station and complete a Factory Restart.
POWER REQUIREMENTS
•2-AA batteries power the thermohygro sensor
•2-AA Alkaline batteries for your weather station
COMPATIBLE SENSOR
•TX141TH-Bv3 is the compatible sensor for this station.
THERMO-HYGRO SENSOR
NO OR DASHES SHOWN FOR OUTDOOR TEMPERATURE/HUMIDITY

La Crosse Technology, Ltd. Page 3
•If sensor loses connection to the weather station for any reason, the weather station
will show NO after 30 minutes.
•The weather station will search for 3 minutes every hour to reconnect with sensor.
•Hold the PLUS (+) button 3 seconds to search for the outdoor sensor.
•Reception Icon will flash while searching for sensor. Outdoor sensor area will show
dashes during the search.
•When sensor is received the icon will be solid.
•If no sensor received, the icon will disappear after 3 minutes of searching if sensor is
not found. NO will again show in the outdoor sensor area.
INACCURATE OUTDOOR TEMPERATURE/HUMIDITY
•The thermo-hygro sensor reads the environment. When the sensor reads high during
the day but not at night it is a mounting problem.
•Side-by-side test: Bring the thermo-hygro sensor in the house and place it next to the
weather station for 2 hours.
•Compare indoor and outdoor temperature. The temperatures should be within 4
degrees to be within tolerance. The humidity should be within 14% to be within
tolerance.
•If the sensor reads correctly when next to your weather station then try a different
location outside.
•Look for heat sources such as sunlight, door or window frames, or reflected heat.
OUTDOOR READINGS ARE STUCK OR SHOW HI OR LO
•Check batteries. Overpowered or underpowered batteries can cause this reading.
•Replace sensor.
INTERMITTENT SENSOR READINGS
•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
patience – 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:
•Hold the + (PLUS) button for 5 seconds to search for sensor.
•Distance/Resistance can cause loss of sensor signal. Avoid having more than one wall,
window, tree etc., between the display and the sensor. UV coated windows may
actually reflect the signal. Stucco walls will absorb the signal.
•Check batteries. This is our primary warranty issue.
SENSOR DRAINS BATTERIES QUICKLY

La Crosse Technology, Ltd. Page 4
•Test a new set of alkaline batteries. Write down the date of installation and the voltage
of the batteries.
•When the batteries fail, please note the date and voltage again. This is helpful in
determining the problem.
•Check the distance and resistance between the sensor and your weather station.
Sensor at the end of the range may work while batteries are fresh but not after they
drain a bit.
•Check for leaking batteries, which may damage the sensor.
HUMIDITY SHOWS DASHES BUT TEMPERATURE WORKS
•The humidity low range is 10% RH. If your local humidity is below 10% you will see this
reading.
•Complete a restart with fresh batteries.
•Replace the sensor.
FAHRENHEIT/CELSIUS
•Enter the program menu to select in Fahrenheit (ºF) or Celsius (ºC).

MOUNTING/POSITIONING

La Crosse Technology, Ltd. Page 6
First, set everything up in the house to be sure it works before mounting the sensor
outside.
TX141TH-Bv3 sensor: Watch sensor mounting video: http://bit.ly/TH_SensorMounting
Place the outdoor sensor in the desired shaded location and the weather station in the
home. Wait approximately one hour before permanently mounting the outdoor sensor to
ensure that there is proper reception.
POSITION
Outdoor:
•Protect the outdoor sensor from standing rain or snow and from the overhead sun,
which can cause it to read incorrectly.
•Mounting under an eave or deck rail works well.
•If you choose, you can construct a small roof or box for the outdoor sensor. Be sure a
box has vents.
•Mount the outdoor sensor on the North side where to prevent sun from causing
incorrect readings.
•Mount at least 6 feet in the air for a strong RF (radio frequency) signal.
•Do not mount the outdoor sensor on a metal fence. This significantly reduces the
effective range.
•Outdoor sensor are water resistant, not waterproof.
•Mount outdoor temperature sensor vertically.
•Avoid more than one wall between the outdoor sensor and the weather station.
•The maximum transmitting range in open air is over 300 feet (91 meters).
•Obstacles such as walls, windows, stucco, concrete and large metal objects can
reduce the range.
•Do not mount near electrical wires, transmitting antennas or other items that will
interfere with the signal.
•RF (radio frequency) signals do not travel well through moisture or dirt.
MOUNT
Option 1:
•Install one mounting screw (not included) into a wall.
•Place the outdoor sensor onto the screw (hanging hole on the backside).
•Gently pull down to lock the screw in place.
Option 2:
•Insert the mounting screw through the front of the outdoor sensor and into the wall.
•Tighten the screw to snug (do not over tighten).
DISTANCE/RESISTANCE/INTERFERENCE
Distance:
•The maximum transmitting range in open air is over 300 feet (91 meters) between the
sensor and the weather station.
•Consider what is in the signal path between the weather station and the sensor.
•Consider the distance the weather station is from other electronics in the home.

La Crosse Technology, Ltd. Page 7
•Resistance:
•Obstacles such as walls, windows, stucco, concrete, and large metal objects can
reduce the range.
•When considering the distance between the sensor and the weather station (300 feet,
91 meters open air) cut that distance in half for each wall, window, tree, bush or other
obstruction in the signal path.
•Closer is better.
•Do not mount the sensor on a metal fence. This significantly reduces the effective
range.
Interference:
•Consider items in the signal path between the sensor and the weather station.
•Simple relocation of the sensor or the weather 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.
•Vegetation is full of moisture and reduces signal.
•Dirt: Receiving a signal through a hill is difficult.

FORECAST ICONS INACCURATE
The forecast icons are determined by the station's barometric pressure reading. Please
allow 7-10 days for barometric calibration. Six forecast icons use changing atmospheric
pressure to predict weather conditions for the next 12-hours with 70-75% accuracy.
When Outdoor temperature is below 32˚F and the forecast is RAIN or T-STORM, the
station will display SNOW.
Forecast Icons:
•Sunny
•Partly Sunny
•Cloudy
•Rain
•T-Storm
•Snow

La Crosse Technology, Ltd. Page 9
•The weather station calibrates barometric pressure based on its location over a period
of time to generate an accurate, personal forecast. Please allow 7-10 days for
barometer calibration.
•The station samples the barometric pressure every twelve minutes. These samples are
averaged hourly and daily then stored in nonvolatile memory. The three-hour pressure
icon change is based off the last four average hourly readings.
•IMPORTANT: As the weather station builds memory, it will compare the current
average pressure to the past forty day average pressure for increased accuracy. The
longer the weather station operates in one location the more accurate the forecast
icons will be.
FORECAST TREND ARROWS
The Forecast Tendency Arrows update every 15 minutes. The trend reflects changes in Pressure over the
past 3 hours.
•UP ARROW: Pressure is rising
•RIGHT ARROW: Pressure is steady
•DOWN ARROW: Pressure is falling
