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 and date 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 Weather Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The weather station 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 Cesium133 atom in a vacuum. For more information on the atomic clock and WWVB please see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm.
QUICK SET-UP GUIDE
1) Insert two AA batteries into the Moon Phase Alarm Clock.
2) Wait 15 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-8053U 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 WS-8053U 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 WS-8053U 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.
I) FUNCTION BUTTONS
There are 3 function buttons located on the front of the Moon Phase Alarm and one on top (snooze). The
function buttons are labeled: SET, +, ALARM, and SNOOZE.
