SETTING THE TIME

There are two methods by which the time and date can be set: 1) Automatically via

.
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 optim
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 signal has been received. If the WWVB time has not been
received after 10 minutes of battery installation, you may

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 lim
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
