Once the batteries are in place, all segments of the LCD will light up briefly. Following the
indoor temperature, date, weekday, and the time, as 12:00, will be displayed. If they are not
shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed user may proceed to the next
step.
After the batteries are inserted, the atomic clock will start receiving data signal from the
sensor. The outdoor temperature should then be displayed on the atomic clock. If this does
not happen after 2 minutes, the batteries will need to be removed from both units and reset
from step 1 and the signal reception icon is no longer shown.

915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE SENSOR
The atomic clock will receive the temperature data within 3 minutes. If the temperature data is not
being received 3 minutes after setting up (the display shows “- - -”), then please check the
following points:
WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time
signal continuously throughout the United States at 60 kHz. The signal can be received up to
2,000 miles away through the internal antenna in the atomic clock. However, due to the nature of
the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic clock will
search for a signal every night when reception is best. The WWVB radio station derives its signal
from the NIST atomic clock in Boulder, Colorado. A team of atomic physicists continually
measures every second of every day to an accuracy of ten billionths of a second a day. These
physicists have created an international standard, measuring a second as 9,192,631,770
vibrations of a Cesium 133 atom in a vacuum. This atomic clock regulates the WWVB transmitter.
1.
The distance of the atomic clock or outdoor temperature sensor should be at least 6 feet (2
meters) away from any interfering sources such as computer monitors or TV sets.
Avoid placing the receiver onto or in the immediate proximity of metal window frames.
Using other electrical products such as headphones or speakers operating on the same
signal frequency (915MHz) may prevent correct signal transmission and reception.
Neighbors using electrical devices operating on the 915MHz signal frequency can also
cause interference.
2.
3.
4.
Once the outdoor temperature is displayed on the atomic clock, the WWVB tower icon in the clock
display will start flashing in the top center of the LCD. This indicates that the clock has detected a
radio signal and is trying to receive it. When the time code is received, the WWVB tower becomes
permanently lit and the time will be displayed.
Note:
When the 915 MHz signal is received correctly, do not re-open the battery cover of either the
outdoor temperature sensor or atomic clock, as the batteries may spring free from the contacts
and force a false reset. Should this happen accidentally then reset all units (see Setting up
above) otherwise transmission problems may occur.
If the tower icon flashes, but does not set the time or the WWVB tower does not appear at all, then
please take note of the following:
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature sensor
to the atomic clock (in open space). However, this depends on the surrounding environment and
interference levels. If no reception is possible despite the observation of these factors, all system
units have to be reset (see Setting up).
•
Recommended distance to any interfering sources like computer monitors or TV sets is a
minimum of 6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window and/ or point its front
or back towards the Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric disturbances are usually less severe and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy deviation
below 1 second.
•
CHANGING THE DISPLAY MODE (DAY, SECONDS, AND TEMPERATURES)
There are 4 possible display modes to view the day, seconds, and temperatures.
The month&date/weekday/indoor temperature/outdoor temperature is the default.
•
To change the display:
Note:
1.

3.
4.
Press the + key. The display should now show the month&date/weekday/seconds/outdoor
temperature.
Press the + key a second time and the display will show the month&date/weekday/indoor
temperature/seconds.
Press the + key a third time and the display will show the month&date/seconds/indoor
temperature/outdoor temperature.
Press the + key a fourth time and the display will return to the normal display.
In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time can be manually set (please refer to notes on Manual time setting).
MOON PHASE
The Moon Phases and their corresponding dates appear in LCD 2. There are 12 visible Moon
Phases that will show in the LCD 2:

FOLDOUT TABLE STANDS

the bottom center edge of the atomic clock, below the battery compartment.
Once the foldout table stands are extended, place the atomic clock in an
appropriate location.

POSITIONING
WALL MOUNTING
Before permanently mounting ensure that the atomic clock is able to receive WWVB signals from
the desired location. Also, extreme and sudden changes in temperature will decrease the
accuracy of the atomic clock, and changes in elevation will result with inaccurate temperatures
readings for the next 12 to 24 hours. These changes will require a 12 to 24 hour wait before
obtaining reliable data.
1) Using a straightedge, horizontally space three screw positions on a wall.
2) Install three mounting screws (not included) into a wall within transmission
range—leaving approximately 3/16 of an inch (5mm) extended from the
wall.
3) Place the atomic clock onto the screws, using the hanging holes on the
backside. Gently pull the atomic clock down to lock the screws into place.
To achieve a true temperature reading, avoid mounting where direct sunlight can reach the
outdoor temperature sensor. It is recommended to mount the outdoor temperature sensor on a
North-facing wall or in any well shaded area. The maximum transmitting range is 330 feet (100
meters) obstacles such as walls, concrete, and large metal objects can reduce the range.
Note:
Always ensure that the atomic clock locks onto the screws before releasing.
Place both units in their desired location, and wait approximately 10 minutes before permanently
mounting to ensure that there is proper reception. The outdoor temperature sensor is not
waterproof and should not be placed anywhere it will become submerged in water or be directly in
the rain.
POSITIONING THE OUTDOOR TEMPERATURE SENSOR
The remote temperature sensor can be mounted with the use of screws
MOUNTING WITH SCREWS
1)
Remove the mounting bracket from the remote temperature
sensor.
Place the mounting bracket over the desired location.
Through the three screw holes of the bracket, mark the
mounting surface with a pencil.
POSITIONING THE ATOMIC CLOCK:
There are two possible ways to mount the atomic clock:

Problem:
Solution:
The LCD is faint.
1) Replace the batteries.
No reception of WWVB signal
1) It may help reception to face the front of the atomic clock in the general
direction of Ft. Collins, Colorado.
•
Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents;
they may mark the displays and casings.
•
•
•
Do not submerge in water.
Immediately remove all low powered batteries to avoid leakage and damage.
Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La
Crosse Technology for repairs.
2) Wait overnight for signal.
3) Be sure the atomic clock is at least 6 feet (2 meters) from any electrical
devices, i.e. TV sets, computers, or other radio controlled clocks.
4) Remove batteries for five minutes, reinsert and leave the unit alone
overnight without pressing any keys.
