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 Moon Phase Clock.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The Moon Phase 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 Moon Phase Clock is regulated by
the WWVB transmitter.
QUICK SET-UP GUIDE
1) Insert two AA batteries into the Moon Phase Clock.
2) Wait 10 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-8001U in a suitable location, where WWVB signals can be
received.
