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 Clock 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 Clock regulates the WWVB transmitter. For more information about WWVB please see the NIST website at http://www.boulder.nist.gov/timefreq/stations/wwvb.htm
QUICK SET-UP GUIDE
1) Insert two fresh AA batteries into the moon phase clock.
2) Wait 10 minutes for WWVB reception.
3) If there is no WWVB reception, manually set the time and date (see
instructions in the Program Mode section).
4) Program the settings.
5) Mount the WS-8007U 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
Remove the battery cover, located on the backside of the moon phase clock and directly below the

2) 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 in itiated, 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 clock 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 clock 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 plac e 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. Press and release the “SNZ” button at any time to exit the Program Mode, or wait approximately 15 seconds for the moon phase clock to automatically return to normal operation.
Your clock will automatically set up with Eastern Time Zone, Daylight Saving Time On, English for the language, 12 hour clock (AM/PM) and °F for temperature.
