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 Digital Atomic Clocks.
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)
Indoor Displays: Use Alkaline batteries. Overpowered or underpowered batteries may
cause loss of indoor readings, missing segments, dim display etc.
Digital Atomic Clock Factory Restart
Explanation: The factory restart returns the wireless thermometer and outdoor sensor to an
“out-of-the-box” state and often resolves an issue.
Factory Restart:
1. Remove all power from outdoor sensor and clock.
2. Press one of the buttons on the clock at least 20 times to clear all memory.
3. Verify that the wireless thermometer is blank before proceeding (some lines are painted on
and will not disappear).
4. Leave batteries out of both units for 15 minutes (very important).
5. Insert fresh Alkaline batteries into the wireless thermometer.
6. Insert fresh batteries into the outdoor sensor.
7. Press the TX button on the outdoor sensor to transmit RF signal.
8. Keep the outdoor sensor 5-10 feet from the wireless thermometer.

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.
During setup, the temperature may change frequently as the clock looks for the transmitter.
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 Digital
Atomic Clock for 2 hours.
Compare indoor and outdoor temperature. The temperatures should be within 4 degrees to
be within tolerance. See the section on accuracy for details.
If the transmitter reads correctly when next to the Digital Atomic Clock 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 Digital Atomic Clock is reading the correct outdoor transmitter.
Place the transmitter in the freezer for an hour and watch the temperature drop on the
Digital Atomic Clock.
Indoor distance test: Please complete the Restart with transmitter and Digital Atomic Clock
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 Digital Atomic Clock. Observe
to see if the Temperature remains on consistently for 1-hour.
If the Temperature 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
reading will hold.
Distance/Resistance can cause loss of transmitter signal.
Check Batteries.
Outdoor Temperature is Stuck or OFL
The last outdoor reading may remain (not change) for several hours when connection is lost.
The outdoor Temperature reading will flash when the connection is first lost or intermittent
between the Digital Atomic Clock 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.

La Crosse Technology, Ltd. Page 5
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 Digital Atomic Clock.
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.
Temperature Trend Arrows
Black arrows next to the indoor and outdoor temperature readings reflect the temperature
change in the past three hours.

RIGHT ARROW: Temperature did not change more than 2°F (1°C) over the past three
hours
DOWN ARROW: Temperature falling more than 2°F (1°C) over the past three hours
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 is well vented.
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 Digital Atomic Clock.
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 Digital Atomic Clock 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.
