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 of 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 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 the 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 and then into the weather station.

6. Insert fresh batteries into the outdoor sensor.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 3

7. Press the TX button on the outdoor sensor to transmit the RF signal.

8. Keep the outdoor sensor 5-10 feet from the weather station.

9. When an 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 200 feet (60

meters, open-air) from the weather 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-BCH outdoor sensor comes packaged with this weather station.

•This station can read up to three outdoor sensors. The TX141TH-BCH allows you to select

channels to use this feature.

Quick Connect

Explanation: Use the quick connect for a weather station and outdoor sensor that has 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 TEMP button for 5 seconds. The outdoor temperature area will flash.

3. Remove the 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 if you hold the TEMP button for 3 seconds.

•The antenna symbol will flash during reception.

•The temperature display will be dashed “---“.

•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 a 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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 4

•Batteries often resolve the connection.

•Distance/Resistance can cause a 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 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: Place the outdoor sensor right next to the weather station for 2 hours.

•Compare indoor and outdoor temperatures. 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., moist climates). If

the 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 the 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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5

•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 the outdoor sensor.

Note: The last outdoor reading may remain (not change) for several hours when the 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 the 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.

•Battery life is over 24 months when using reputable battery brands for both Alkaline and

Lithium batteries.

Outdoor Humidity goes to dashes when the temperature is cold.

•The outdoor temperature/humidity sensor designed to work with this weather station will

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.

The 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: A outdoor sensor that has fallen into a puddle, snow, or other standing water, will likely have

water damage and need to be replaced. Outdoor sensors are water resistant, not waterproof.

Heat Index:

•Heat Index combines the effects of heat and humidity.

•A heat Index is what the temperature feels to a human being.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 7

•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 TEMP button once and the Heat Index

will show instead of the outdoor ambient temperature.

Note: The 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 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 TEMP 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

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 8

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

Outdoor:

•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 the

box has vents.

•Mount the outdoor sensor on the North side to prevent the sun from causing incorrect

readings.

•Mount at least 6 feet in the air for a strong RF (radio frequency) signal.

•Do not mount the outdoor sensor on a metal fence. This significantly reduces the effective

range.

•Outdoor sensors are water resistant, not waterproof.

•Mount outdoor temperature sensor vertically.

•Avoid more than one wall between the outdoor sensor and the weather station.

•The HIimum 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.

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 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 outdoor sensor.

•The maximum transmitting range in the 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.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 9

Distance/Resistance/Interference

Distance:

•The transmitting range in the open air is over 300 feet (91 meters) between the outdoor

sensor and the weather station. This range is in the open air with ideal conditions.

•Consider what is in the signal path between the weather station and the outdoor sensor.

•Avoid placing electronics in the signal path between the weather station and the outdoor

sensor.

Resistance:

•Obstacles such as walls, floors, 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.

•It is difficult for RF (radio frequency) signal to travel through a hill.
