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.
A) ATOMIC CLOCK
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.

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.

FEATURES & OPERATIONS
I) CHANGING DISPLAY MODE (DAY, SECONDS, AND TEMPERATURE)
There are three possible display modes to view the day, seconds, and temperature. The month & date/ weekday/ indoor temperature is the
default.
To change the display:
1) Press and release the “+” button. The display should now show the month & date/ weekday/ seconds.
2) Press and release the “+” button a second time and the display will now show the month & date/ seconds/ indoor temperature.
3) Press and release the “+” button a third time and the display will return to the normal display.
II) INDOOR TEMPERATURE
The Indoor Temperature appears on the right side of the Date LCD. The temperature is checked every 10 seconds, and updated whenever
there is a change.
MOUNTING
There are two possible ways to mount the atomic clock:
• use of the foldout table stands, or
SET
Function Buttons
Foldout Table Stands
Hanging Holes
• 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.
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, 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.
