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 appear 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 found. 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.

PROGRAM MODE

To enter the Program Mode hold down the “SET” button for 2
seconds, until “-5EST” flashes in the Date LCD. The Program Mode
is laid out in a manner that allows you to program each function
separately, or you can follow the instructions entirely to program
the Moon Phase Clock. Complete programming is usually done for the
initial set-up, and will require you to skip step 1 of programming
sections III through VIII. Press the “SNOOZE” button at any time
to exit the Program Mode, or wait approximately 15 seconds for the
Moon Phase Alarm to automatically return to normal operation.
