AC Power
The design of this forecast 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 forecast 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.
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.
Forecast Station Factory Restart
Explanation: The factory restart returns the forecast station and outdoor sensor to an “out-of-the-box”
state and often resolves an issue.
Factory Restart:
1. Remove all power (batteries and AC) from outdoor sensor and forecast station.
2. Press one of the buttons on the forecast station at least 20 times to clear all memory.
3. Verify that the forecast station is blank before proceeding (there are some painted lines that will not
disappear).
4. Leave both units without power for 15 minutes (very important).
5. Insert the AC power cord into the wall outlet then into the forecast 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 forecast station.
9. When RF connection is established, the temperature will appear on the station. Allow the outdoor
sensor and forecast station to sit together for 15 minutes to establish a strong connection.
10. Do not press buttons for 15 minutes.
La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 2
For optimum 433MHz transmission, place the outdoor sensor no more than 300 feet (91 meters, open
air) from the forecast station.
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 forecast station.
The TX141TH-A and TX141TH-B (433MHz) outdoor sensors are compatible with this forecast station.
Quick Connect
Explanation: Use the quick connect for a forecast 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, forecast station together inside, and place the units 5-10 feet apart with
nothing between them.
2. Hold the SENSOR SEARCH button on the forecast 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 forecast station.
Factory Restart: If the above procedure does not work, please try the factory reset.
Outdoor Temperature Signal Strength
Explanation: The forecast station will search for the outdoor temperature/humidity outdoor sensor for 3
minutes after batteries are installed or when 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 forecast station and the outdoor sensor.
Batteries often resolve the connection.
Distance/Resistance can cause loss of connection between the outdoor sensor and the forecast
station.
Turn the forecast 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 3
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 forecast 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 forecast station, try a different location outside.
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 forecast station is reading the correct outdoor sensor. Place the outdoor sensor
in the freezer for an hour and watch the temperature drop on the forecast station.
Indoor distance test: Please complete the Restart with outdoor sensor and forecast 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 forecast 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 forecast 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.
