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 Moon Phase Clock.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The Moon Phase Alarm 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 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. This Moon Phase Alarm is regulated by
the WWVB transmitter.

QUICK SET-UP GUIDE

1) Insert two AA batteries into the Moon Phase Alarm Clock.

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) Place the WS-8055U in a suitable location, where WWVB signals can be

received.

DETAILED SET-UP GUIDE
I) BATTERY INSTALLATION

Note:

To avoid start-up problems make sure that the batteries do not spring free.

A) MOON PHASE CLOCK

1) Remove the battery

cover, located on the
backside of the unit.

2) Observe the correct

polarity, and install 2
AA batteries.

3) Replace the battery

cover.

Note:

After the
batteries have been installed a tone will sound, and all the LCD ’s (Liquid
Crystal Display) will briefly light up. Then the indoor temperature, the date
as “1/ 1”, the weekday as “MON”, and the Moon Phase will be displayed .
Also, the time will appear as “-:--” for approximately 1 minute. Then the
WWVB search is automatically initiated, and a tower icon appears and
flashes with the time colon (no tower icon will ap pear if the WWVB is too
weak to be detected). While the WWVB search is being conducted various
numbers will appear in the time display. The numbers “0 ”, “1”, or “8”
will appear in the hour position and the seconds will appear in the minute
display. The Moon Phase Alarm will either display the WWVB time, or
discontinue the search after 10 minutes if the time is not foun d. When the
search is cancelled “-:--”will appear in the time LCD. The Moon Phase
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
remain, if not, another search will take place every hour(up to 6:00 am)
until the signal is found 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.
