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
temperature 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)
Temperature Station:Use alkaline batteries. Overpowered or underpowered
batteries may cause loss of indoor readings, missing segments, dim display etc.
Temperature Station Factory Restart
FACTORY RESTART:
RESTART DISTANCE: For best results please bring the outdoor transmitter in the
house and place 5-10 feet from the display unit.
REMOVE POWER: Remove batteries from the transmitter and from the
temperature station.
DISCHARGE ELECTRICITY: With the power removed, press one of the buttons
on the display at least 20 times to clear all memory. Please do this even if the
display is blank to remove any random electricity. Verify the display is blank.
UNPOWERED FOR 15 MINUTES: Let the temperature station and transmitter rest
without batteries for 15 minutes.
IMPORTANT: Failure to allow a temperature station to rest for 15 minutes can
result in failure to connect with the outdoor transmitter or missing segments on
the display.
Note: The instruction manual describes a setup for a new unit that has not had
time to build up residual electricity.
BATTERIES: Please be sure you are using fresh batteries testing to a minimum
of 1.48, on a voltmeter that reads in numbers.
TRANSMITTER: Place batteries into the outdoor transmitter first. Make sure
batteries are installed according to the diagrams in the battery compartment.
TEMPERATURE STATION: Install batteries into the temperature station according
to the diagram in the battery compartment.
CONNECTION: Allow the transmitter and display to remain 5 feet apart for 15
minutes to establish a strong connection. Do not press buttons at this time. You
should see a reading on the outdoor temperature area in the first minute.
See the section on mounting and distance/resistance/interference for details on
mounting the outdoor transmitter.

Outdoor Temperature Transmitter
Compatible Outdoor Transmitters
A TX38U-IT outdoor transmitter is compatible with this Temperature Station.
Power Requirements
2-AAA batteries power the outdoor transmitter.
We recommend alkaline batteries for the transmitter.
Dashes shown for Outdoor Temperature
Dashes means the connection is lost between the Temperature Station and the
outdoor transmitter.
Batteries often resolve the connection.
Distance/Resistance can cause loss of connection between the transmitter and
the Temperature Station.
Reorientation of the Temperature Station 90 degrees towards the outdoor
transmitter may provide better reception.
Complete a factory restart.
Inaccurate Outdoor Temperature Reading
The outdoor transmitter reads the environment. When mounted in the home it
will read inside temperature.
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 Temperature Station for 2 hours.
Compare indoor and outdoor temperature. The temperatures should be within 4
degrees to be within tolerance.
If the transmitter reads correctly when next to the Temperature Station then try
a different location outside.
Look for heat sources such as sunlight, door or window frames, or reflected
heat.
Intermittent Outdoor Temperature
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.
Freezer test: Confirm the Temperature Station is reading the correct outdoor
transmitter. Place the transmitter in the freezer for an hour and watch the
temperature drop on the Temperature Station.
Indoor distance test: Please complete the Restart with transmitter and
Temperature 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

La Crosse Technology, Ltd. Page 4
Temperature Station. Observe to see if the temperature remains on consistently
for 1-hour.
If the temperature remains while in the house then it is likely a
distance/resistance issue. Move the transmitter to find a location where the
temperature reading will hold.
Distance/Resistance can cause loss of transmitter signal.
Check Batteries.
Outdoor Temperature Shows OFL
OFL stands for Outside Factory Limits.
The outdoor transmitter is sending and the Temperature Station is receiving the
signal.
Check Batteries.Overpowered or underpowered batteries can cause this
reading.
Replace outdoor transmitter.
Outdoor Temperature Changes Constantly
You may have an additional compatible outdoor transmitter within range.
Occasionally a neighbor will have a compatible outdoor transmitter that is within
range.
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. This is helpful in
determining the problem.
Check the distance and resistance between the transmitter and temperature
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.

the Indoor or Outdoor mode. Temperature will then reset to the current values.
Mounting/Positioning Outdoor Transmitter
Mount outdoor temperature transmitters vertically and under a bit of an
overhang.
Protect the outdoor transmitter from standing rain or snow, and from the
overhead sun, which can cause it to read incorrectly. Generally, mounting under
an eave or deck rail works well.
Construct a small roof or box for the transmitter if you do not have an overhang.
Please be sure the box has vents.
Mount the transmitter on the North side to prevent sun from causing incorrect
readings.
Mount at least 6 feet in the air for a strong signal.
Outdoor transmitters are water resistant but not water proof.
Avoid more than one wall between the transmitter and the Temperature Station.
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.
Place the outdoor transmitter and the Temperature Station in the desired
shaded locations, and wait approximately 1-hour before permanently mounting
the transmitter to ensure that there is proper reception.
Do not mount the transmitter on a metal fence. This significantly reduces the
effective range.
MOUNT

Remove the mounting bracket from the remote temperature transmitter.
Place the mounting bracket over the desired location (wall or table).
Through the screw holes of the bracket, mark the mounting surface with a
pencil.
Screw mounting bracket onto the mounting surface. Ensure that the screws are
flush with the bracket.
Insert the remote temperature transmitter into the bracket.
Note: Mounting with adhesive tape is not recommended as a permanent mounting
solution. Only use the adhesive tape during set-up process.
Position Temperature Station
The Temperature Station has a wide base to sit on a desk or table.
Choose a location 6 feet or more from electronics such as cordless phones,
gaming systems, televisions, microwaves, routers, baby monitors, etc., which
can prevent signal reception.
Place within range of the outdoor transmitter.
Be aware of electrical wires and plumbing within a wall. This will interfere with
signal reception.
The maximum transmitting range in open air is 330-feet (100 meters).
Obstacles such as walls, windows, stucco, concrete, and large metal objects can
reduce the range.
Distance/Resistance/Interference
Distance:
The maximum transmitting range in open air is over 330-feet (100 meters)
between the outdoor transmitter and the Temperature Station.
Consider what is in the signal path between the Temperature Station and the
transmitter.
Consider the distance the Temperature Station is located away from other
electronic in the home.
Resistance:
Obstacles such as walls, windows, stucco, concrete, and large metal objects can
reduce the range.
When considering the distance between the transmitter and the Temperature
Station (330 feet 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 the transmitter on a metal fence. This significantly reduces the
effective range.
Interference:
Consider items in the signal path between the transmitter and the Temperature
Station.
Sometime a simple relocation of the transmitter or the Temperature Station will
correct the interference issue.
Windows can reflect the radio signal.
