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 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 Sensors: 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

FACTORY RESTART:

Remove batteries from outdoor sensor and clock.

Press one of the buttons on the clock at least 20 times to clear all memory.

Verify that the clock is blank before proceeding (there may be lines painted on the screen

that will show when power is removed).

Leave both units without power for 15 minutes (very important).

Insert the fresh batteries into the clock.

Insert fresh batteries into the outdoor sensor.

Press the TX button on the outdoor sensor to transmit RF signal.

Keep the outdoor sensor 5-10 feet from the forecast station.

When RF connection is established, the temperature will appear on the station. Allow the

outdoor sensor and clock to sit together for 15 minutes to establish a strong connection.

Do not press buttons for 15 minutes.

For optimum 434MHz transmission, the outdoor sensor should be a distance of no more

than 200 feet (60 meters, open air) from the clock.

See the section on mounting and distance/resistance/interference for details on mounting

the outdoor sensor.

La Crosse Technology, Ltd Page 3

Digital Atomic Clock: Hold the -/°C/°F button on the back of the clock for 5 seconds to

switch the temperature display from Fahrenheit to Celsius.

KW5012FSK Transmitter:Press the °C/°F button under the battery cover to switch the

sensor temperature display from Fahrenheit to Celsius

Flashing Outdoor Temperature

The outdoor Temperature reading will flash when the connection is first lost or intermittent

between the clock and the outdoor sensor.

Distance/Resistance is generally the cause of intermittent connection or loss of connection

between the sensor and the clock.

Check the position of the clock. Turn the clock 90 degrees towards the outdoor sensor for

better reception.

Try the quick connect or factory restart.

Batteries often resolve the connection issue.

Dashes shown for Outdoor Temperature

Dashes means the connection is lost between the clock and the outdoor sensor.

This sensor reads down to –4 °F. when the temperature is below that, the outdoor

temperature can show OFL, HH.H, dashes or stick at a number.

Batteries often resolve the connection.

Distance/Resistance can cause loss of connection between the sensor and the clock.

Reorientation of the clock 90 degrees towards the outdoor sensor may provide better

reception.

Try the quick connect or factory restart.

Quick Connect

Bring the sensor and clock together inside and have both units 5-10 feet apart with nothing

between them.

Hold the SEARCH button on the clock for 5 seconds until the Temperature area starts to

flash.

Remove battery cover and press and release the TX button to send the signal.

Wait for 2 minutes for the outdoor Temperature to appear.

Factory Restart: If the above procedure does not work, please try the factory reset.

Inaccurate Outdoor Temperature Reading

When the sensor reads high during the day but not at night it is a positioning problem.

Side-by-side test: Bring the outdoor sensor in the house and place it next to the clock for 2

hours.

La Crosse Technology, Ltd Page 4

Compare indoor and outdoor temperature. The temperatures should be within 4°to be within

tolerance.

If the sensor reads correctly when next to the clock then try a different location outside.

Look for heat sources such as sunlight, door or window frames, or reflected heat.

Intermittent Outdoor Temperature

What is the temperature? This sensor reads down to –4 degrees F. when the temperature is

below that, the outdoor temperature can show OFL, dashes or stick at a number. If the

temperature is hovering at about –4 degrees Fahrenheit, the temperature may come and go.

RF (radio frequency) communication may come and go occasionally. This can be normal in

some environments (e.g. moister climates). If sensor signal is lost, please wait 2-4 hours for

the signal to reconnect on its own.

Move the outdoor sensor to a closer location.

Freezer test: Confirm the clock is reading the correct outdoor sensor. Place the sensor in

the freezer for an hour and watch the temperature drop on the clock.

Indoor distance test: Please complete the Restart with sensor and 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 sensor to

another room with one wall between the sensor and the 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 sensor to different locations outside to find a location where the Temperature

reading will hold.

Distance/Resistance can cause loss of sensor signal.

Check Batteries.

Outdoor Temperature Is Stuck or LL.L. HH.H

What is the temperature? This sensor reads down to –4 °F. When the temperature is

below that, the outdoor temperature can show LL.L, HH.H, dashes or stick at a number. If

the temperature is hovering at about –4 °F, the temperature may come and go.

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 clock and the outdoor sensor.

Check Batteries. Overpowered or underpowered batteries can cause this reading.

Replace outdoor sensor.

Outdoor Sensor Fell and No Longer Works

If there is no physical damage to the outdoor sensor, the fall may not have caused internal

damage.

An outdoor sensor that has fallen into a puddle or other standing water or snow may have

water damage.

Sensors are water resistant, not waterproof.

A fall can shock the sensor or the batteries in the sensor.

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.

La Crosse Technology, Ltd Page 5

Outdoor Temperature Changes Constantly

You may have an additional compatible outdoor sensor within range.

Occasionally a neighbor will have a compatible outdoor sensor that is within range.

During setup, the temperature may change frequently as the clock looks for the sensor.

Outdoor 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 the sensor and clock. 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 the sensor.

Battery life is over 24 months when using reputable battery brands for both Alkaline and

Lithium batteries.

Mounting/Positioning Outdoor Sensor

Mount outdoor Temperature sensors vertically and under a bit of an overhang.

Protect the outdoor sensor 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 sensor if you do not have an overhang. Please be sure

the box is well vented.

Mount the sensor on the north-side to prevent sun from causing incorrect readings.

Mount at least 6 feet in the air for a strong signal.

Outdoor sensors are water resistant but not water proof.

Avoid more than one wall between the sensor and the 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 sensor and the clock in the desired shaded locations, and wait

approximately 1 hour before permanently mounting the sensor to ensure that there is proper

reception.

Do not mount the sensor on a metal fence. This significantly reduces the effective range.

MOUNT

Choose a location for the sensor that is within range of the clock and under an overhang for

accuracy.

Install one mounting screw into a wall leaving approximately ½ inch (12.7mm) extended.

Place the sensor onto the screw, using the hanging hole on the backside.

Gently pull the sensor down to lock the screw into place.

Note: Always ensure that the sensor locks onto the screw before releasing.

Position Digital Atomic Clock

Mount the clock near an exterior wall with the front or back facing toward Ft. Collins,

Colorado for best WWVB reception.

The clock should be six feet from other electronics or wireless devices to best receive the

outdoor temperature sensor signal.

La Crosse Technology, Ltd Page 6

Foldout Table Stand:

A foldout table stands are located on the back of the clock.

Pull the stands out from the bottom of the Digital Atomic Clock, below the battery

compartment.

Wall Mount

Use a straightedge to place one screw position on a wall to match the hanging hole on the

back of the clock. Install one mounting screw (not included) into a wall within transmission

range of the outdoor sensor—leaving approximately 3/16 of an inch (5mm) extended from

the wall.

Place the clock onto the screw, using the hanging hole on the backside.

Gently pull the clock down to lock the screw into place.

Note: Always ensure that the clock locks onto the screw before releasing.

Distance/Resistance/Interference

Distance:

The maximum transmitting range in open air is over 200 feet (60 meters) between the

outdoor sensor and the clock.

Consider what is in the signal path between the clock and the sensor.

Consider the distance the clock 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 sensor and the clock (200 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 sensor on a metal fence. This significantly reduces the effective range.

Interference:

Consider items in the signal path between the sensor and the clock.

Sometime a simple relocation of the sensor or the clock will correct the interference issue.

Windows can reflect the radio signal.

Metal will absorb the RF (radio frequency) signal.

Stucco is held to the wall by a metal mesh.

Transmitting antennas (ham radio, emergency dispatch center, airports, military base etc.)

Electrical wires (utilities, cable etc.)

Vegetation is full of moisture and reduces signal.

Dirt: Trying to receive a signal through a hill is difficult.
