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-6003U 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 Cover
A) ATOMIC CLOCK
SET
Battery Compartment
1) Remove the battery cover, located on the backside of the unit and directly
above 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 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.

flashes in the Date LCD. The Program Mode is laid out in a manner that allows you to
4
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.

MOUNTING
Hanging Holes
Function Buttons
SET
Foldout Table Stands
There are two possible ways to mount the atomic clock:
•
•
use of the foldout table stands, or
wall mounting.
I) FOLDOUT TABLE STAND
The foldout table stand leg is located on the backside,
directly below the battery cover and function buttons.
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
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.
