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.
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
Battery Compartment

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 +.

MOUNTING
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.

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.
