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 outdoor 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 outdoor sensor to an
“out-of-the-box” default state and often resolves an issue.
Factory Restart:
1. Remove all power (batteries and AC) from outdoor 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 outdoor sensor.
7. Press the TX button on the outdoor sensor to transmit RF signal.
8. Keep the outdoor sensor 5-10 feet from the weather station.
9. When RF connection is established, the temperature will appear on the station. Allow the
outdoor 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 outdoor sensor no more than 300 feet (91
meters, open air) from the weather station.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 3
See the section on mounting and distance/resistance/interference for details on
mounting the outdoor sensor.
Outdoor Temperature Sensor
Compatible Outdoor sensors
The TX141TH-Bv2 outdoor sensor comes packaged with this weather station.
The TX141TH-A, TX141TH-Av2 and TX141TH-B (433MHz) outdoor sensors are
compatible with this weather station.
Quick Connect
Explanation: Use the quick connect for a weather station and outdoor 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 outdoor 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 outdoor temperature area will flash.
3. Remove battery cover from the outdoor sensor and press and release the TX button to
send the signal.
4. Wait for 2 minutes for the outdoor temperature to appear on the weather station.
Factory Restart: If the above procedure does not work, please try the factory reset.
Outdoor Temperature Signal Strength
Explanation: The weather station will search for the outdoor 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 Outdoor Temperature
Explanation: Dashes mean the connection is lost between the weather station and the
outdoor sensor.
Batteries often resolve the connection.
Distance/Resistance can cause loss of connection between the outdoor sensor and the
weather station.
Turn the weather station 90 degrees towards the outdoor sensor to provide better
reception. This allows more antenna surface to face the outdoor sensor signal.
Try the quick connect or factory restart.
Power Requirements
2-AA batteries power the outdoor sensor.
We recommend Alkaline batteries for the outdoor sensor.
You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.
Inaccurate Outdoor Temperature Reading
Explanation: High outdoor temperature readings are generally a location issue. Low
outdoor temperature readings are power related or a sensors going bad.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 4
The outdoor sensor reads the environment where it is mounted. When mounted inside
the home, it will read inside temperature/humidity.
When the outdoor sensor reads high during the day, but not at night, it is a positioning
problem.
Look for heat sources such as sunlight, door or window frames or reflected heat.
Side-by-side test: Place the outdoor sensor right next to the weather station for 2 hours.
Compare indoor and outdoor temperature. The temperatures should be within 4 degrees
to be within tolerance.
If the outdoor sensor reads correctly when next to the weather station, try a different
location outside.
Intermittent Outdoor 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 outdoor sensor signal is lost, please wait 2-4 hours for the signal
to reconnect on its own.
Move the outdoor sensor to a closer location.
Distance/Resistance can cause loss of outdoor sensor signal.
Check Batteries.
Freezer test: Confirm the weather station is reading the correct outdoor sensor (not a
neighbor’s sensor). Place the outdoor sensor in the freezer for an hour and watch the
temperature drop on the weather station.
Indoor distance test: Please complete the Restart with outdoor 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 outdoor temperature area, move the
outdoor sensor to another room with one wall between the outdoor 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 outdoor sensor to different locations outside to find a location where the
temperature reading will hold.
Outdoor Temperature is stuck or HH.H, LL.L
Explanation: These symbols are error messages indicating the outdoor sensor is outside of
its readable range.
Check Batteries. Overpowered or underpowered batteries can cause this reading.
Replace outdoor sensor.
Note: The last outdoor reading may remain (not change) for several hours when connection
is lost. The outdoor temperature reading will flash when the connection is first lost or
intermittent.
Outdoor 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 outdoor sensor and weather station.
Outdoor sensors at the end of the range may work while batteries are fresh but not after
they drain a bit.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5
Check for leaking batteries, which may damage the outdoor sensor.
Battery life is over 24 months when using reputable battery brands for both Alkaline and
Lithium batteries.
Outdoor Humidity goes to dashes when temperature is cold.
The outdoor temperature/humidity sensor designed to work with this weather station
may drop the outdoor 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.
Outdoor sensor fell. The sensor no longer works
Explanation: If there is no physical damage to the outdoor sensor, the fall may not have
caused internal damage. A fall can shock the outdoor sensor or the batteries in the outdoor
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: An outdoor sensor that has fallen into puddle, snow, or other standing water, will
likely have water damage and need replacement. Outdoor sensors are water resistant, not
waterproof.
