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 Projection alarm.
However, due to the nature of the Earth’s Ionosphere, recept i on is very limited during
daylight hours. The Projection alarm will search for a signal every night when reception
is best.
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 Cesium­133 atom in a vacuum. For more detail, visit http://www.boulder.nist.gov/timefreq.htm.
To listen to the NIST time, call [phone]. 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. 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 .10 seconds per day.

QUICK SET-UP GUIDE

1) Insert two AA batteries into the Projection alarm and/or plug into wall

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 WT-5600 in a suitable location, where WWVB signal can be

received.

6) The projector will activate and remain on if the alarm clock is plugged in. If

only batteries are used, the projector will only be activated when a button is
pressed.

7) See the “Features” section for instructions on projection direction, etc.

DETAILED SET-UP GUIDE

BATTERY INSTALLATION

1. Remove the battery cover.

2. Observe the correct polarity and install 2 AA batteries.

3. In addition or instead of

inserting batteries, the AC
adapter can be used. Simply
plug the adapter into the
receptacle on the bottom of
the alarm clock and then
plug in adapter.

4. Replace the battery cover.

5. The projector will activate and remain on if the alarm clock is plugged in. If

only batteries are used, the projector will only be activated when a button is
pressed. The projection is a red light, not harmful under normal usage,
although care should be taken to not look directly into the light.

Note

: After the batteries have been installed a tone will sound and th e LCD

(Liquid Crystal Display) will activate. The date and U.S. map will be
displayed and the time will appear as “-:--”. The WWVB search is
automatically initiated and a tower icon appears and flashes with the time
colon (no tower icon will appear if the WWVB is too weak to be detected
and the time display will remain on “-:--”). While the WWVB search is
being conducted various numbers will appear in the time disp lay. After 10
minutes, the Projection Alarm will either display the WWVB time, or
discontinue the search if the time is not found. If the search is can celled “-:-

-” will remain in the time LCD. The Projection Alarm will conduct a
WWVB search every hour until the first signal is found. Once the WWVB
time is found, a search is automatically conducted nightly at midnight. If the
signal is found at midnight, the tower icon will appear. If not, another
search will take place every hour (until 6:00 am) until the signal is received
successfully. If no signal is found during this period, the tower icon will not
appear and the clock will search again at 12:00 am the next night.
