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.
