Batteries
Half of all warranty issues can be resolved with fresh batteries of the appropriate
voltage.
We suggest name brand alkaline batteries for forecast 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.
Forecast Station Factory Restart
DISTANCE: bring the transmitter, forecast station together inside, and place
both 5-10 feet apart with nothing between them.
REMOVE POWER: Remove batteries from the transmitter and forecast station.
DISCHARGE ELECTRICITY: Press one of the buttons on the forecast station least
20 times to clear all memory. Verify that the forecast station is blank before
proceeding.
UNPOWERED 15 MINUTES: Let the forecast station and transmitter sit with
power removed for at least 15 minutes.

La Crosse Technology, Ltd. Page 3
Note: Failure to allow a display to rest for 15 minutes can result in failure to
connect with the outdoor sensor or missing segments on the display. The
instruction manual describes a setup for a new unit that has not had time to
build up residual electricity.
TRANSMITTER: Insert fresh batteries into the transmitter, observing the correct
polarity.
Keep the transmitter 5-10 feet from the Forecast Station.
FORECAST STATION: Insert fresh alkaline batteries in the Forecast 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 Forecast station to sit together for 15 minutes to establish a
strong connection.
PLACE TRANSMITTER OUTSIDE: For optimum 915MHz transmission, place the
outdoor transmitter a distance of no more than 330 feet (100 meters, open air)
from the Forecast Station.
See the section on mounting and distance/resistance/interference for details on
mounting the outdoor transmitter.
Outdoor Temperature/Humidity Transmitter
Compatible Outdoor Transmitters
The TX29UDTH-IT, TX21U-IT, TX44UDTH-IT, TX29UTH-IT and TX28U-IT sensors
(915MHz) will work with this station.
Power Requirements
2-AA batteries power the outdoor transmitter.
We recommend alkaline batteries for the transmitter.
Dashes shown for Outdoor Temperature/Humidity
Dashes means the connection is lost between the forecast station and the
outdoor transmitter.
Check the reading on the transmitter display.
Batteries often resolve the connection.
Distance/Resistance can cause loss of connection between the transmitter and
the Forecast Station.
Reorientation of the Forecast station 90 degrees towards the outdoor transmitter
may provide better reception by the antenna.
Try the factory restart.
Outdoor Temperature/Humidity Changes Constantly
The forecast station can read up to three outdoor transmitters.
Check the channel indicator. If it switches between 1, 2 or 3, your forecast
station is reading additional transmitters.
Check if the transmitter display reads the same as a channel on the forecast
station.
Press and release the SNOOZE/CH button to settle on one channel.

La Crosse Technology, Ltd. Page 4
Note: When first powered up it is natural for the forecast 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 Forecast 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 14% to be within
tolerance.
If the transmitter reads correctly when next to the forecast 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: The forecast station may be reading more than one
transmitter.
Freezer test: Confirm the forecast station is reading the correct outdoor
transmitter. Place the transmitter in the freezer for an hour and watch the
temperature drop on the forecast Station.
Indoor distance test: Please complete the Restart with transmitter 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
transmitter to another room with one wall between the transmitter and the
forecast 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 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.

La Crosse Technology, Ltd. Page 5
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. This is helpful in
determining the problem.
Check the distance and resistance between the transmitter and forecast 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.
