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.
We suggest name brand Alkaline batteries for indoor displays.
Use Alkaline or Lithium batteries in the outdoor sensors.
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”
state and often resolves an issue.
Factory Restart:
1. Remove all power 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 (some lines are painted on and will not
disappear).
4. Leave batteries out of both units for 15 minutes (very important).
5. Insert fresh Alkaline batteries 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.
See the section on mounting and distance/resistance/interference for details on mounting the outdoor
sensor.

The TX141TH-B, TX141TH-Bv2 and TX141TH-A (433MHz) outdoor sensors are compatible with this
weather station.

La Crosse Technology, Ltd. Page 3
Quick Connect
Explanation: The quick connect is used for a weather station and outdoor sensor that have been working
but lost connection due to interference or low batteries. This is not 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 SENSOR SEARCH button on the weather station. 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 outdoor sensor for 3
minutes after batteries are installed or the SENSOR SEARCH button is held 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.
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: Bring the outdoor 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.
If the outdoor sensor reads correctly when next to the weather station, try a different location outside.

La Crosse Technology, Ltd. Page 4
Intermittent Outdoor Temperature/Humidity
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. 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 indication 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.
Check for leaking batteries, which may damage the outdoor sensor.
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 needs to be replaced. Outdoor sensors are water resistant, not waterproof.
Replacement Outdoor Sensors

Temperatures.
Reset MAX data: Hold the MAX TEMP button for 5 seconds and the Indoor and all Outdoor
Maximum Temperatures will reset. The temperature area will show dashes briefly then return to
current temperatures
Heat Index/Dew Point temperature
Explanation: Heat Index combines the effects of heat and humidity. It is the apparent temperature of how
hot it feels to a human being. As humidity increases, the body is unable to cool effectively. The
temperature will feel warmer.
View Heat Index: From a normal display, press the HEAT/DEW button once and Heat Index will show
instead of the outdoor ambient temperature.
Note: Heat index will be the same number as the temperature until the outdoor 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 a normal display, press the HEAT/DEW button twice and Dew
Point will show instead of the outdoor ambient temperature. The words “Dew Point”will show near
outdoor temperatures.
Note: Dew Point is lower than the actual temperature.
Mounting/Positioning Outdoor sensor
First: Place the outdoor sensor in the desired shaded location and the weather station in the home. Wait
approximately 1 hour before permanently mounting the outdoor sensor to ensure that there is proper
reception.
POSITION
Mount outdoor temperature outdoor sensors vertically.
Protect the outdoor sensor from standing rain or snow and from the overhead sun, which can cause it
to read incorrectly.

La Crosse Technology, Ltd. Page 6
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.
Outdoor sensors are water resistant, not waterproof.
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.
Do not mount the outdoor sensor on a metal fence. This significantly reduces the effective range.
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:

Place within range of the outdoor sensor.
The maximum transmitting range in open air is 300 feet (91 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 outdoor 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 outdoor sensor.
Avoid placing electronic in the signal path between the weather station and the outdoor sensor.
Resistance:
Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce the range.
When considering the distance between the outdoor sensor and the weather station (300 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 outdoor sensor on a metal fence. This significantly reduces the effective range.
Interference:
Consider items in the signal path between the outdoor sensor and the weather station.
Sometimes a simple relocation of the outdoor 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.
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.

Moon Phase
Explanation: The Moon Phase is based on the date manually set on the weather station. The moon is
divided by 6 sections, showing 12 phases of the moon.
Waxing indicates growing or expanding illumination and happens after a new moon.
Waning indicates decreasing illumination and occurs after a full moon.
Crescent refers to the moon being less than half-illuminated. Crescents can be waning or waxing.
Gibbous describes a moon phase when more than half is illuminated. Gibbous can be waxing or
waning.
New Moon occurs when the moon is between the earth and sun, so the illuminated portion of the
moon is on the backside facing the sun and we cannot see it. After a new moon, the illuminated
portion will increase or wax until the full moon occurs.
Full Moon occurs when the earth, moon and sun are in approximate alignment, with the moon and
the sun on opposite sides of the earth. The illuminated portion of the moon faces the earth, giving us
complete visibility of one side of the entire moon. After a full moon, the illuminated portion will
decrease or wane until the new moon occurs.
First Quarter and Last Quarter moons occur when the moon is at a 90-degree angle to the earth
and sun. We see half of the moon illuminated and the other half is in shadow.
Weather Station is dim
Explanation: Most weather stations have a gray background. Place the weather station at eye level, to
determine if it is dim. Weather stations that sit in the sunlight can develop a cloudy film over time.
