Press and release the SET key to confirm the Time setting and continue to the Year setting.  
Note:  
The unit will still try to receive the signal every day despite it being manually set. When it does  
receive the signal, it will change the manually set time into the received time. During reception  
attempts the WWVB tower icon will flash. If reception has been unsuccessful, then the WWVB  
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.  
YEAR SETTING  
The year can be selected sequentially from 2003 to 2029 and will then start over again (default  
setting 2004). None of the digits of the year will be visible on the lower LCD display however the  
year must be correct as it affects the day of the week display.

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.

WALL MOUNTING  
1) Using a straight edge, horizontally space at about 2“ (50 mm) three screw  
positions on a wall.  
2) Install three mounting screws (not included) into a wall —leaving  
approximately 0.19“ (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.  
Note:  
Always ensure that the atomic clock locks onto the screws before releasing.  
TROUBLESHOOTING  
Problem:  
Solution:  
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.  
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.  
Problem:  
Solution:  
Problem:  
Solution:  
Hour is incorrect (minute and date are correct).  
1) Be sure the correct time zone and daylight saving time are selected.  
"OFL“ appears in the indoor temperature section of the LCD  
1) Move the atomic clock to an area with warmer or cooler surrounding  
temperature. Current surrounding temperatures are outside measuring  
range.  
CARE AND MAINTENANCE:  
Avoid placing the unit in areas prone to vibration and shock as these may cause damage.  
Avoid areas where the unit can be exposed to sudden changes in temperature, i.e. direct  
sunlight, extreme cold and wet/moist conditions as these will lead to rapid changes which  
reduces the accuracy of readings.

When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or  
scouring agents.  
Do not submerge the unit into water.  
Immediately remove all low powered batteries to avoid leakage and damage. Replace only with  
new batteries of the recommended size.  
Do not make any repairs to the unit. Please return it to the original point of purchase. Opening  
and tampering with the units may invalidate the warranty.
