TO INSTALL AND REPLACE BATTERIES IN THE ATOMIC CLOCK
The atomic clock uses 3 x AA, 1.5V batteries. To install and replace the batteries, please follow
the steps below:
1. Pull down on the tab at the top of the battery cover and lift up to remove the cover.
2. Insert batteries observing the correct polarity (see marking inside battery compartment).
3. Replace compartment cover.
DO NOT SET THE CLOCK.
SETTING UP:
Alkaline batteries are recommended for use. Avoid using rechargeable
batteries.
1. Place batteries in the atomic clock. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
2. After 15 minutes the indoor area on your clock should have a temperature and humidity
showing. If not, remove batteries, wait 15 minutes and repeat step one.
3. After the clock receives the WWVB time code reception will automatically start. This
reception typically takes between 5-10 minutes in good conditions. If after 15 minutes the
WWVB time has not been received, use the “SET” key to manually enter the set-up mode
and change either the time or date in order to activate the WWVB reception (see manual
settings below). The clock will then automatically attempt to receive the WWVB time from
12:00 am through 6:00 am each day (attempts WWVB reception every full hour within this
time frame). When this is successful, the received time will override the manually set time.
The date is also updated with the received time (Please refer to notes on “Radio controlled
time” and “Manual time setting”).
4. After the time signal has been received or the search mode has been manually stopped the
indoor temperature will be displayed.
Note:
When changing batteries in the unit, ensure that the batteries do not spring free from the contacts.
Always wait at least 15 minutes after removing the batteries before reinserting, otherwise start up
problems may occur.

tower icon will not appear but reception will still be attempted the following hour.
WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB
reception every full hour within this time frame). When the time signal is received for example at
1:00 am, the atomic clock will not attempt to receive the WWVB signal for the remaining hours
until 6:00 am. Therefore, the next signal attempt will take place between 12:00 am and 6:00 am
the next day. The other times WWVB reception takes place, are upon setup and after manual time
set exiting mode. Reception is generally not possible during daylight hours due to the interference
of the sun.

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.
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.
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:
•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.
Note:
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 appear in the middle of the lower LCD. There are 12 visible Moon Phases that
will show in the LCD:

POSITIONING
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.
POSITIONING THE ATOMIC CLOCK:
There are two possible ways to mount the atomic clock:
•use of the foldout table stands, or
•wall mounting
FOLDOUT TABLE STAND
The foldout table stand legs are located on the backside, at the lower corners, just
below the battery cover. The hinges are towards the edges of the atomic clock, and
the ends (with no hinge) need to be folded out towards the edge. Once the foldout
table stands are extended, place the atomic clock in an appropriate location.
