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.
Temperature Station Factory Restart
Explanation: The factory restart returns the temperature 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 temperature station.
2. Press one of the buttons on the temperature station at least 20 times to clear all
memory.
3. Verify that the temperature station is blank before proceeding (there are some painted
lines that will not disappear).
4. Leave batteries out of both units for 15 minutes (very important).
5. Insert fresh Alkaline batteries into the temperature 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 temperature station.
9. When RF connection is established, the temperature will appear on the station. Allow
the outdoor sensor and temperature 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 temperature 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 TX141-Bv3outdoor sensor comes packaged with this temperature station.
•The TX141-B (all versions) (433MHz) are compatible with this temperature station.
Quick Connect
Explanation: Use the quick connect for a temperature 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 temperature station together inside and place the units
5-10 feet apart with nothing between them.
2. Hold the SENSOR button on the temperature 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 temperature station.
•Factory Restart: If the above procedure does not work, please try the factory reset.
Outdoor Temperature Signal Strength
•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 SENSOR 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.
Dashes show for Outdoor Temperature
Explanation: Dashes mean the connection is lost between the temperature station and
the outdoor sensor.
•Batteries often resolve the connection.
•Distance/Resistance can cause loss of connection between the outdoor sensor and
the temperature station.
•Turn the temperature 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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 4
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.
•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
temperature 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 temperature 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 temperature station is reading the correct outdoor sensor. Place
the outdoor sensor in the freezer for an hour and watch the temperature drop on the
temperature station.
Indoor distance test: Please complete the Restart with outdoor sensor and temperature
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
temperature 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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5
•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 temperature
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.
•Battery life is over 24 months when using reputable battery brands for both Alkaline
and Lithium batteries.
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.

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.
•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 temperature 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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 7
•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:
•Insert the mounting screw through the front of the outdoor sensor and into the wall.
•Tighten the screw to snug (do not over tighten).
Position Temperature Station

•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 temperature station. This range is in open air with ideal
conditions.
•Consider what is in the signal path between the temperature station and the
outdoor sensor.
•Avoid placing electronic in the signal path between the temperature 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 temperature
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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 8
•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 temperature
station.
•Sometimes a simple relocation of the outdoor sensor or the temperature 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.
•It is difficult for RF (radio frequency) signal to travel through a hill.
