BATTERIES

La Crosse Technology, Ltd. Page 2
•Half of all warranty issues can be resolved with fresh batteries of the appropriate
voltage.
•We suggest name brand alkaline 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.
•Alkaline batteries manufactured this year will have an expiration date 10 years 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.
•Good name brand alkaline batteries make less noise, which reduces the chance of RF
(radio frequency) interference from the battery compartment. A minimum voltage of
1.48V for each battery is necessary for proper performance.
WEATHER STATION FACTORY RESTART
The factory reset will return your weather station to its default settings. This will clear all
previous recorded history, so you may want to write down data before taking this step.
1. Bring all sensors in the house within 5 feet of your station.
2. Remove batteries from station and all three sensors. Leave out for 15 minutes.
3. Press any button on your station 20 times.
4. After 15 minutes, insert fresh batteries into each sensor and into your station.
5. Wait 15 minutes to establish a strong connection. Place sensors outside.
BATTERY CHANGE
•After changing batteries in your sensor, hold the SEARCH button for 5 seconds to
search for all your sensors.
•If this fails to connect your sensor to your station, bring your sensor about 5 feet from
your station and complete a Factory Restart.
POWER REQUIREMENTS
•2-AA Alkaline batteries for your weather station
•2-AA batteries for each sensor.
COMPATIBLE SENSORS
•TX141TH-BCH with selectable channels.
http://www.lacrossetechnology.com/tx141th-bch-temperature-humidity-sensor
•The TX141TH-ACH and TX141TH-BCH (433MHz) outdoor sensors are compatible with
this weather station.
THERMO-HYGRO SENSOR
DASHES SHOWN FOR OUTDOOR TEMPERATURE/HUMIDITY/WINDSPEED

La Crosse Technology, Ltd. Page 3
•Dashes means the unit have lost connection between the display and the outdoor
sensor.
•Batteries are the most common problem.
•Distance/Resistance can cause loss of sensor signal. Avoid having more than 1 wall,
window, tree etc., between the display and your sensor. UV coated windows may
actually reflect the signal. Stucco walls will absorb the signal.
•It may be helpful to orient the weather 90 degrees towards your sensor for better
reception.
•Sensors operate best when elevated at least 6 feet.
•Remove the batteries from your sensor for 2 minutes. Replace the batteries in the
Thermohygro sensor and after 5 minutes press and hold the SEARCH button for 5
seconds. Wait 10 minutes. If the unit does not receive a reading from all your sensors,
please try the factory reset.
INACCURATE OUTDOOR TEMPERATURE/HUMIDITY
•The thermo-hygro sensor reads the environment. When one of your sensors reads
high during the day but not at night it is often a mounting problem.
•
Side-by-side test
: Bring the thermo-hygro sensor in the house and place it next to
your station for 2 hours.
•
Alternatively, place your inaccurate sensor right next to a working sensor for 2
hours
.
•Compare temperatures. The temperatures should be within 4 degrees to be within
tolerance. The humidity should be within 14% to be within tolerance.
•If your sensor reads correctly when next to your station then try a different location
outside.
•Look for heat sources such as sunlight, door or window frames, or reflected heat.
OUTDOOR READINGS ARE STUCK OR HI OR LO
•Check batteries. Overpowered or underpowered batteries can cause this reading.
•Replace sensor.
INTERMITTENT SENSOR READINGS
•RF (radio frequency) communication may come and go occasionally. This can be
normal in some environments (e.g. moister climates).
•If a sensor goes out, please wait 2-4 hours for it to reconnect on its own. Please be
patience – these stations can reconnect on, after many hours out.
•RF (radio frequency) communication is not always 100% on.
•Certain temporary conditions can cause it to go out for a time (e.g. 100% humidity).
•IF the signal is lost, the RX will display the LAST DATA recorded from sensor for 10
minutes.
•After that 10 minutes if the signal does not come back then display dashes "--".
•After 30 minutes, start looking for the RF signals automatically.
If a miss happens:

La Crosse Technology, Ltd. Page 4
•Hold the SEARCH button for 3 seconds to search for all three sensors.
•The lines below each channel number will flash while searching (up to 3 minutes).
•The station will search for missing sensors for 3 minutes every hour.
•The lines will be solid when the sensor is connected.
•If a sensor for a certain channel is not found, the lines below the channel indicator will
not show.
•Distance/Resistance can cause loss of sensor signal. Avoid having more than 1 wall,
window, tree etc., between the display and your sensor. UV coated windows may
actually reflect the signal. Stucco walls will absorb the signal.
•Check batteries. This is our primary warranty issue.
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. This is helpful in
determining the problem.
•Check the distance and resistance between your sensor and Weather station. 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 your sensor.
HUMIDITY SHOWS DASHES, OR HI | LO BUT TEMPERATURE WORKS
•The humidity low range is 10% RH. If your local humidity is below 10% you will see this
reading.
•Complete a restart with fresh batteries.
•Replace your sensor.
FAHRENHEIT/CELSIUS
Enter the program menu to select in Fahrenheit (ºF) or Celsius (ºC).
DAILY HI | LO TEMPERATURE/HUMIDITY RECORDS
•All HI/LO temperature/humidity records reset automatically at 12:00 (midnight).
•Press the +/HI button to view indoor and outdoor HI temperature/humidity records for
all three sensors.
•Press the -/LO button to view indoor and outdoor LO temperature/humidity records for
all three sensors
SENSOR AREA IS BLANK (NO DASHES OR NUMBERS)
•Check that other areas of your station read properly. There may be a problem with
your station.

MOUNTING/POSITIONING
First, set everything up in the house to be sure it works before mounting your sensors
outside. With 3 sensors you can position sensors inside and outside to meet your needs.
Outdoor:
•Protect your 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.
•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 your 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).
Indoor:
•Position away from door or window frames and away from vents.
•Be sure the sensor will not be in direct sunlight shining in a window as this will cause
incorrect readings.
•Common use for extra sensors are basements, baby’s room etc.
•Be sure to mount the sensor vertically.
DISTANCE/RESISTANCE/INTERFERENCE
Distance:
•The maximum transmitting range in open air is over 300 feet (91 meters) between your
sensors and your station.

La Crosse Technology, Ltd. Page 6
•Consider what is in the signal path between your station and your sensors.
•Consider the distance your station is from other electronics in the home.
Resistance:
•Obstacles such as walls, windows, stucco, concrete, and large metal objects can
reduce the range.
•When considering the distance between your sensor and your station (300 feet, 91
meters open air) cut that distance in half for each wall, window, tree, bush or other
obstruction in the signal path.
•Closer is better.
•Do not mount your sensors on a metal fence. This significantly reduces the effective
range.
Interference:
•Consider items in the signal path between your sensors and your station.
•Simple relocation of your sensors or your station may correct an interference issue.
•Windows can reflect the radio signal.
•Metal will absorb the RF (radio frequency) signal.
•Stucco held to the wall by a metal mesh will cause interference.
•Transmitting antennas from: ham radios, emergency dispatch centers, airports, military
bases, etc. may cause interference.
•Electrical wires, utilities, cables, etc. may create interference if too close.
•Vegetation is full of moisture and reduces signal.
•Dirt: Receiving a signal through a hill is difficult.
