AC Power
The design of this weather station is to use AC power (5-volt) as primary power source.
When operating with the AC power cord, the backlight can be on continually.
When operating on AC power, batteries are optional and are not required in the weather
station.
The backlight will turn off or operate at high or low intensity at your discretion.
Batteries
Explanation: Many problems are resolved with fresh batteries of the appropriate voltage.
Many items sent in under warranty work when tested with fresh batteries. Batteries
manufactured this year will have an expiration date 10 years (or more) 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.
Use Alkaline or Lithium batteries in the remote sensor.
A minimum voltage of 1.48V for each battery is necessary for proper performance.
Use batteries dated at least 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.
Good name brand batteries make less noise, which reduces the chance of RF (radio
frequency) interference from the battery compartment.
Weather Station Factory Restart
Explanation: The factory restart returns the weather station and remote sensor to an “out-
of-the-box” default state and often resolves an issue.
Factory Restart:
1. Remove all power (batteries and AC) from remote sensor and weather station.
2. Press one of the buttons on the weather station at least 20 times to clear all memory.
3. Verify that the weather station is blank before proceeding (there may be lines painted on
the screen that will show when there is no power).
4. Leave both units without power for 15 minutes (very important).
5. Insert the AC power cord into the wall outlet then into the weather station.
6. Insert fresh batteries into the remote sensor.
7. Press the TX button on the remote sensor to transmit RF signal.
8. Keep the remote sensor 5-10 feet from the weather station.
9. When RF connection is established, the temperature will appear on the station. Allow the
remote sensor and weather station to sit together for 15 minutes to establish a strong
connection.
10. Do not press buttons for 15 minutes.
For optimum 433MHz transmission, place the remote sensor no more than 200 feet (60
meters, open air) from the weather station.
See the section on mounting and distance/resistance/interference for details on
mounting the remote sensor.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 3
Quick Connect
Explanation: Use the quick connect for a weather station and remote sensor that have
been working but lost connection due to interference or low batteries. This is not the same
as a thorough factory reset.
1. Bring the remote sensor and weather station together inside, and place the units 5-10
feet apart with nothing between them.
2. Hold the HEAT/DEW button for 5 seconds. The remote temperature area will flash.
3. Remove battery cover from the remote sensor and press and release the TX button to
send the signal.
4. Wait for 2 minutes for the remote temperature to appear on the weather station.
Factory Restart: If the above procedure does not work, please try the factory reset.
Remote Temperature Sensor
Compatible Remote sensors
The TX141TH-Bv2 remote sensor comes packaged with this weather station.
The TX141TH-A, TX141TH-Av2 and TX141TH-B (433MHz) remote sensors are
compatible with this weather station.
Remote Temperature Signal Strength
Explanation: The weather station will search for the remote temperature/humidity sensor
for 3 minutes after installing batteries or after holding the HEAT/DEW button for 3 seconds.
The antenna symbol will flash during reception.
The temperature display will be dashes “---“.
If synchronization fails once, the antenna will lose one bar.
If synchronization fails twice, the antenna will lose two bars.
If RF (radio frequency) reception fails five times, the antenna symbol will show without
bars.
The antenna will show full display with successful RF (radio frequency) reception.
Dashes show for Remote Temperature
Explanation: Dashes mean the connection is lost between the weather station and the
remote sensor.
Batteries often resolve the connection.
Distance/Resistance can cause loss of connection between the remote sensor and the
weather station.
Turn the weather station 90 degrees towards the remote sensor to provide better
reception. This allows more antenna surface to face the remote sensor signal.
Try the quick connect or factory restart.
Power Requirements
2-AA batteries power the remote sensor.
We recommend Alkaline batteries for the remote sensor.
You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.
Inaccurate Remote Temperature Reading
Explanation: High remote temperature readings are generally a location issue. Low remote
temperature readings are power related or a sensors going bad.
The remote sensor reads the environment where it is mounted. When mounted inside
the home, it will read inside temperature/humidity.
When the remote sensor reads high during the day, but not at night, it is a positioning
problem.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 4
Look for heat sources such as sunlight, door or window frames or reflected heat.
Side-by-side test: Place the remote sensor right next to the weather station for 2 hours.
Compare indoor and remote temperature. The temperatures should be within 4 degrees
to be within tolerance.
If the remote sensor reads correctly when next to the weather station, try a different
location outside.
Intermittent Remote Temperature
Explanation: Intermittent problems are the hardest to resolve. RF (radio frequency)
communication may come and go occasionally. This can be normal in some environments
(e.g. moister climates). If remote sensor signal is lost, please wait 2-4 hours for the signal
to reconnect on its own.
Move the remote sensor to a closer location.
Distance/Resistance can cause loss of remote sensor signal.
Check Batteries.
Freezer test: Confirm the weather station is reading the correct remote sensor (not a
neighbor’s sensor). Place the remote sensor in the freezer for an hour and watch the
temperature drop on the weather station.
Indoor distance test: Please complete the Restart with remote sensor and weather station
5-10 feet apart and inside to establish a strong connection.
After 15 minutes, if there is a reading in the remote temperature area, move the remote
sensor to another room with one wall between the remote sensor and the weather
station.
Observe to see if the temperature remains on consistently for 1 hour.
If the temperature remains on while in the house, then it is likely a distance/resistance
issue.
Move the remote sensor to different locations outside to find a location where the
temperature reading will hold.
Remote Temperature is stuck or HH.H, LL.L
Explanation: These symbols are error messages indicating the remote sensor is outside of
its readable range.
Check Batteries. Overpowered or underpowered batteries can cause this reading.
Replace remote sensor.
Note: The last remote reading may remain (not change) for several hours when connection
is lost. The remote temperature reading will flash when the connection is first lost or
intermittent.
Remote sensor drains batteries quickly
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.
Check the distance and resistance between the remote sensor and weather station.
Remote sensors 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 remote sensor.
Battery life is over 24 months when using reputable battery brands for both Alkaline and
Lithium batteries.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5
Remote Humidity goes to dashes when temperature is cold.
The remote temperature/humidity sensor designed to work with this weather station
may drop the remote humidity and dew point reading in cold temperatures.
The humidity and dew point will return when the temperature rises. This is how the
sensor came from the factory. The temperature itself will continue to read.
Remote sensor fell. The sensor no longer works
Explanation: If there is no physical damage to the remote sensor, the fall may not have
caused internal damage. A fall can shock the remote sensor or the batteries in the remote
sensor. Batteries that have fallen on a hard surface may be damaged and unable to function
properly.
Complete a Restart with fresh batteries.
Use Batteries dated at least 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.
Note: A remote sensor that has fallen into puddle, snow, or other standing water, will likely
have water damage and need replacement. Remote sensors are water resistant, not
waterproof.

Temperature/Humidity Trend Arrows
Explanation: The indoor and remote temperature (2°F / 1°C) and humidity (3% RH) trend
indicators update every 30 minutes or less. These trends represent temperature changes
over the past three hours.
Example: At 11:00, the trend arrows will reflect changes in temperature or humidity since
8:00. At 11:30, the trend arrows will reflect changes in temperature or humidity since
8:30, etc.
Up Arrow:
Temperature has risen in the past 3 hours.
Humidity has risen in the past 3 hours.
Right Arrow:
Temperature has not changed in the past 3 hours.
Humidity has not changed in the past 3 hours.
Down Arrow:

and humidity values for indoor and remote data.
Heat Index/Dew Point
Heat Index:
Heat Index combines the effects of heat and humidity.
Heat Index is what the temperature feels to a human being.
As humidity increases, the body is unable to cool effectively.
The temperature will feel warmer.
View Heat Index: From the default time display, press the HEAT/DEW button once and
Heat Index will show instead of the remote ambient temperature.
Note: Heat index will be the same number as the temperature until the remote temperature
is above 26.7°C (80°F).
Dew Point Temperature:
Dew Point Temperature is the saturation point of the air, or the temperature to which
the air has to cool in order to create condensation.
The higher the dew points, the higher the moisture content of the air at a given
temperature.
View Dew Point Temperature: From the default time display, press the HEAT/DEW
button twice and Dew Point will show instead of the remote ambient temperature. The
words “Dew Point”will show near remote temperatures.
Note: Dew Point is lower than the actual temperature.
Mounting/Positioning Remote sensor
First: Place the remote sensor in the desired shaded location and the weather station in the
home. Wait approximately 1 hour before permanently mounting the remote sensor to
ensure that there is proper reception.
POSITION
Outdoor:
Protect the remote 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 remote sensor. Be sure a
box has vents.
Mount the remote 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 remote sensor on a metal fence. This significantly reduces the
effective range.
Remote sensors are water resistant, not waterproof.
Indoor or Outdoor:
Mount remote temperature sensor vertically.
Avoid more than one wall between the remote sensor and the weather station.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 7
The maximum transmitting range in open air is over 200 feet (60 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 remote 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 remote sensor and into the wall.
Tighten the screw to snug (do not over tighten).
Position Weather Station
The weather station has a pull out stand to sit on a desk or table or can be wall
mounted.
Place within range of the remote sensor.
The maximum transmitting range in open air is 200 feet (60 meters).
Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce
the range.
Choose a location 6 feet or more from electronics such as cordless phones, wireless
gaming systems, televisions, microwaves, routers, baby monitors, etc., which can
prevent signal reception.
Be aware of electrical wires and plumbing within a wall. This will interfere with RF (radio
frequency) signal reception.
Distance/Resistance/Interference
Distance:
The maximum transmitting range in open air is over 300 feet (91 meters) between the
remote sensor and the weather station. This range is in open air with ideal conditions.
Consider what is in the signal path between the weather station and the remote sensor.
Avoid placing electronics in the signal path between the weather station and the remote
sensor.
Resistance:
Obstacles such as walls, floors, windows, stucco, concrete and large metal objects can
reduce the range.
When considering the distance between the remote sensor and the weather station (200
feet open air), cut that distance in half for each wall, window, tree, bush or other
obstruction in the signal path.
Closer is better.
Windows reflect the RF (radio frequency) signal.
Metal absorbs the signal and reduces the range.
Stucco has a metal mesh that absorbs the signal.
Do not mount the remote sensor on a metal fence. This significantly reduces the
effective range.
Interference:
Consider items in the signal path between the remote sensor and the weather station.
Sometimes a simple relocation of the remote sensor or the weather station will correct
the interference.
Windows can reflect the radio signal.
Metal will absorb the RF (radio frequency) signal.
Stucco has a metal mesh that absorbs signal.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 8
Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports,
military bases, etc.)
Electrical wires (utilities, cable, etc.)
Vegetation is full of moisture and reduces signal.
It is difficult for RF (radio frequency) signal to travel through a hill.
