Batteries
Half of all warranty issues can be resolved with fresh batteries of the appropriate voltage.
We suggest name brand alkaline batteries for indoor displays such as Weather Stations.
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 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.
Outdoor Transmitters: Use Alkaline batteries (or Lithium for temperatures below - 20°F/-
28.8°C)
Weather Stations: (Optional battery use). Use alkaline batteries. Overpowered or
underpowered batteries may cause loss of indoor readings, missing segments, dim display
etc.
Note: When operating the Weather Station on batteries only, the backlight will only appear
for 8 seconds, when you press the SNOOZE/LIGHT button.
La Crosse Technology, Ltd. Page 2
A/C Power
The design of this Weather Station is to use a/c power (5-volt) as primary power source.
When operating with the a/c power cord the backlight can be on continually.
When operating on a/c power, batteries are optional and not required in the Weather
Station.
The backlight will turn off or operate at high or low intensity at your discretion.
IMPORTANT: When operating on a/c power, to avoid interference, the backlight and USB
charging port will turn off while the Weather Station searches for the WWVB signal. The
backlight will return after the 2-10 minute search (which occurs during the late night or early
morning hours). Then the USB charging port will resume working.
Weather Station Factory Restart
FACTORY RESTART:
DISTANCE: Bring the transmitter and Weather Station together inside and place both 5-10
feet apart with nothing between them.
REMOVE POWER: Remove batteries and a/c cord from transmitter and Weather Station.
DISCHARGE ELECTRICITY: Press one of the buttons on the Weather Station at least 20
times to clear all memory. Verify that the Weather Station is blank before proceeding.
UNPOWERED 10 MINUTES: Let the Weather Station and transmitter sit with power
removed for at least 10 minutes.
WEATHER STATION: Insert 5-volt A/C power cord or install fresh alkaline batteries in the
Weather Station.
TRANSMITTER: Insert fresh batteries into the transmitter, observing the correct polarity.
PRESS TX BUTTON: Press the TX button on the back of remote Transmitter to transmit RF
(radio frequency) signal. Keep the transmitter 5-10 feet from the Weather Station.
WAIT: Wait for 5 minutes for the outdoor temperature/humidity to appear.
CONNECTION: When RF (radio frequency) connection is established, the respective
temperature & humidity will appear on the main unit. Allow the transmitter and Weather
Station to sit together for 15 minutes to establish a strong connection.
PLACE TRANSMITTER OUTSIDE: For optimum 433MHz transmission, place the outdoor
transmitter a distance of 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 transmitter.
Outdoor Temperature/Humidity Transmitter
Compatible Outdoor Transmitters
A TX14TH-LCD-B outdoor transmitter comes packaged with this Weather Station.
The TX14TH, TX14TH-LCD-G and TX14TH-LCD-B (433MHz) transmitters are compatible
with this Weather Station.
Quick Connect
DISTANCE: Bring the transmitter and Weather Station together inside and have both units
5-10 feet apart with nothing between them.
WEATHER STATION: Hold the CH button on the Weather Station for 5 seconds until the
temperature/humidity area starts to flash.
TRANSMITTER: Remove battery cover and press and release the TX button to send the
signal.
WAIT: Wait for 2 minutes for the outdoor temperature/humidity to appear.
Factory Restart: If the above procedure does not work, please try the factory reset below.
La Crosse Technology, Ltd. Page 3
Power requirements
2-AA batteries power the outdoor transmitter.
We recommend alkaline batteries for the transmitter.
You may choose to use lithium batteries for temperatures below - 20°F/-28.8°C.
Dashes shown for Outdoor Temperature/Humidity
Dashes means the connection is lost between the Weather Station and the outdoor
transmitter.
Batteries often resolve the connection.
Distance/Resistance can cause loss of connection between the transmitter and the Weather
Station.
Reorientation of the Weather Station 90 degrees towards the outdoor transmitter may
provide better reception. This allows more antenna surface to face the transmitter signal.
Try the quick connect or factory restart.
Outdoor Temperature/Humidity changes constantly
The Weather Station can read up to three outdoor transmitters.
Check the channel indicator. If it switches between 1, 2 or 3, your Weather Station is
reading additional transmitters.
The word AUTO will appear below the channel indicator when the Weather Station is set to
channel scroll.
Press and release the CH button to settle on one channel.
Note: When first powered up it is natural for the Weather Station to search across all three
channels for up to 15 minutes for outdoor transmitters.
You may have an additional compatible outdoor transmitter within range.
Occasionally a neighbor will have a compatible outdoor transmitter that is within range.
Inaccurate Outdoor Temperature/Humidity reading
The outdoor transmitter reads the environment. When mounted in the home it will read
inside temperature/humidity.
When the transmitter reads high during the day but not at night it is a positioning problem.
Side-by-side test: Bring the outdoor transmitter 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. The humidity should be within 10% to be within tolerance. See the
section on accuracy for details.
If the transmitter reads correctly when next to the Weather Station then try a different
location outside.
Look for heat sources such as sunlight, door or window frames, or reflected heat.
Intermittent Outdoor Temperature/Humidity
RF (radio frequency) communication may come and go occasionally. This can be normal in
some environments (e.g. moister climates). If transmitter signal is lost, please wait 2-4 hours
for the signal to reconnect on its own.
Move the outdoor transmitter to a closer location.
Check Channels: Confirm that the channel selected on the outdoor transmitter matches the
channel shown on the Weather Station.
La Crosse Technology, Ltd. Page 4
Freezer test: Confirm the Weather Station is reading the correct outdoor transmitter. Place
the transmitter in the freezer for an hour and watch the temperature drop on the Weather
Station.
Indoor distance test: Please complete the Restart with transmitter 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 transmitter
to another room with one wall between the transmitter and the Weather Station. Observe to
see if the temperature/humidity remains on consistently for 1-hour.
If the temperature/humidity remains on while in the house then it is likely a
distance/resistance issue. Move the transmitter to different locations outside to find a
location where the temperature/humidity reading will hold.
Distance/Resistance can cause loss of transmitter signal.
Check Batteries.
Outdoor Temperature/Humidity is stuck or OFL
The last outdoor reading may remain (not change) for several hours when connection is lost.
The outdoor temperature/humidity reading will flash when the connection is first lost or
intermittent between the Weather Station and the outdoor transmitter.
Check Batteries. Overpowered or underpowered batteries can cause this reading.
Replace outdoor transmitter.
Outdoor transmitter fell and no longer works
If there is no physical damage to the outdoor transmitter, the fall may not have caused
internal damage.
An outdoor transmitter that has fallen into a puddle or other standing water or snow may
have water damage.
Transmitters are water resistant, not waterproof.
A fall can shock the transmitter or the batteries in the transmitter. 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.
Outdoor Transmitter 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 transmitter and Weather Station.
Transmitters 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 transmitter.
Battery life is over 24 months when using reputable battery brands for both Alkaline and
Lithium batteries.
MIN/MAX Temperature readings
This Weather Station will show the daily minimum and maximum temperatures starting at
midnight (12:00 AM).
The Weather Station will automatically reset the min/max temperatures at midnight (12:00
AM).
You can manually reset the MIN/MAX data at any time.
