II. PROGRAMMING
A. SETTING THE TIME
There are two methods by which the time
and date can be set: 1) Automatically via
WWVB reception, or 2) Manually.
B. WWVB (Radio-Controlled Time)
This method requires you to do nothing,
except wait for the signal to be received,
and to select a time zone. Reception
usually takes approximately 6-10 minutes
during optimal conditions. The best
conditions for reception is at night,
between midnight and 6:00 am—when
there is less atmospheric interference. To
keep your time as accurate as possible, the
alarm clock conducts a WWVB search
every night between these hours, and
overrides any manually set time. The
WWVB tower icon (appearing in the
TIME LCD) will flash when a signal-
search is in progress and a signal is being
received, and will remain steady when the
5
signal has been received. If the WWVB
time has not been received after 10
minutes of battery installation, you may
manually set the time or wait for the
WWVB reception.
About Radio-Controlled Time signal,
WWVB:
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 and date 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 alarm clock. However, due to the
nature of the Earth’s Ionosphere, reception
is very limited during daylight hours. The
alarm 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
6
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. For more
information please see the NIST website at
www.boulder.nist.gov/timefreq/stations/wwvb.htm.
