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.
Projection of Time and/or Remote Temperature
When plugged into an AC outlet the projection alarm can continuously
project the time and/or remote temperature.
9. When operating on batteries alone the projection alarm will only project
when a button is pressed.
10. The projection will auto-focus for display from three to six feet away. A
dark surrounding will be necessary to clearly see the projection.
11. The default is projecting time (Hour and Minutes). The projection alarm
can be se to project the time (M0), remote temperature (M1), or alternating
