ABOUT WWVB (Radio Controlled Time)  
The NIST (National Institute of Standards and Technology—Time  
and Frequency Division) WWVB radio station 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 is  
continually measuring every second, of every day, to an accuracy  
of ten billionths of a second per 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.

QUICK SET-UP GUIDE  
1) Insert two AA batteries into the Atomic Clock.  
2) Wait 15 minutes for WWVB reception.  
3) If there is no WWVB reception, manually set the time and date  
(instructions in the Program Mode).  
4) Program the settings.  
5) Mount the WS-6002U in a suitable location, where WWVB  
signals can be received.

DETAILED SET-UP GUIDE  
I) BATTERY INSTALLATION  
Note: To avoid start-up problems make sure that the batteries  
do not spring free.  
Battery Compartment  
SET  
Battery Cover  
A) ATOMIC CLOCK  
1) Remove the battery cover, located on the backside of the  
function buttons.  
2) Observe the correct polarity, and install 2 AA batteries.  
3) Replace the battery cover.  
Note: After the batteries have been installed all the LCD’s  
(Liquid Crystal Display) will briefly light up. Then the indoor  
temperature, the date as “1/ 1” and the weekday as “MON”  
will be displayed. Also, the time will appear as “-:--” for  
approximately 1 minute. Then the WWVB search is  
automatically initiated, and a tower icon appears and flashes  
with the time colon (no tower icon will appear if the WWVB is  
too weak to be detected). While the WWVB search is being  
conducted various numbers will appear in the time display.  
The numbers “0”, “1”, or “8” will appear in the hour position  
and the seconds will appear in the minute display. The Atomic  
Clock will either display the WWVB time, or discontinue the  
5
 
search after 10 minutes if the time is not found. When the  
search is cancelled “-:--”will appear in the time LCD. The  
Atomic Clock will conduct a WWVB search every hour until the  
first signal is found. Once the WWVB time is found, a search is  
automatically conducted nightly at midnight. If the signal is  
found at midnight, the tower icon will remain, if not, another  
search will take place every hour (up to 6:00 am) until the  
signal is found successfully. If no signal is found during this  
period, the tower icon will not appear and the clock will search  
again at 12:00 am the next night.

PROGRAM MODE  
To enter the Program Mode hold down the “SET” button for 2  
seconds, until “-5EST” flashes in the Date LCD. The Program  
Mode is laid out in a manner that allows you to program each  
function separately, or you can follow the instructions entirely to  
program the Atomic Clock. Complete programming is usually  
done for the initial set-up, and will require you to skip step 1 of  
programming sections III through VIII. Wait approximately 15  
seconds for the Atomic Clock to automatically return to normal  
operation.  
I) FUNCTION BUTTONS  
There are 2 function buttons located on the backside of the  
Atomic Clock. The function buttons are labeled: SET and +.

Foldout Table  
Stand  
There are two possible ways to mount the atomic clock:  
use of the foldout table stand, or  
wall mounting.  
I) FOLDOUT TABLE STAND  
The foldout table stand leg is located on the backside of the atomic  
clock. The hinge is towards the center of the atomic clock, and the  
end (with no hinge) needs to be folded in towards the center. Once  
the foldout table stand is extended, place the atomic clock in an  
appropriate location.  
II) WALL MOUNTING  
11  
 
1) Using a straightedge, horizontally space at 3-15/16 of an inch  
(100.58mm) 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.  
MAINTENANCE & CARE  
Extreme temperatures, vibrations, and shock should be avoided  
to prevent damage to the units.  
Clean displays and units with a soft, damp cloth. Do not use  
solvents or scouring agents—they may mark and damage the  
displays and casings.  
Do not submerge in water.  
Immediately remove all low powered batteries to avoid leakage  
and damage. Replace with new batteries only, and of  
recommended size.  
Opening the casings invalidates the warranty. Do not try to  
repair the units. Contact La Crosse Technology for Repairs.  
TROUBLESHOOTING  
Problem: The LCD is faint.  
Solution: 1) Replace the batteries.  
Problem: “OFL” appears in the LCD.  
Solution: 1) Move unit to an area with warmer or cooler  
surrounding temperature. Current surrounding  
temperatures are outside measuring range.  
Problem: No reception of WWVB signal.  
Solution: 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  
from any electrical devices, i.e. TV sets,  
12  
 
computers, or other radio controlled clocks.  
4) Remove batteries for five minutes, reinsert  
and leave the unit alone overnight without  
pressing buttons.  
5) If problems persist contact La Crosse  
Technology.  
Problem: Hour is incorrect (minute and date are correct).  
Solution: 1) Be sure correct time zone and daylight  
saving time are selected.
