B. RADIO-CONTROLLED TIME AND DATE
1. The projection alarm will automatically search for the time signal upon
initial set-up and every night.
2. When the signal is being received, there will be a “tower” icon flashing
to the left of the time display.
3. When the time signal has been received successfully, the tower icon
will remain steady until midnight.
4. 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 Projection alarm.
5. Due to the nature of the Earth’s Ionosphere, reception is very limited
during daylight hours. The Projection alarm will search for a signal
every night when reception is best.
6. The WWVB radio station receives the time data 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.
7. For more detail, visit http://www.boulder.nist.gov/timefreq.htm. To listen
to the NIST time, call (303) 499-7111. This number will connect you to
an automated time, announced at the top of the minute in “Coordinated
Universal Time”, which is also known as Greenwich Mean Time
(GMT). This time does not follow Daylight Saving Time changes. After
the top of the minute, a tone will sound for every second.
8. It is possible that your Projection Alarm may not be exactly
on the
second due to the variance in the quartz. However, the clock will adjust
the quartz timing over the course of several days to be very accurate;
under 0.10 seconds per day.
