Battery Compartment
Battery Cover
A. ATOMIC CLOCK
1.Remove the battery cover, located on the backside of the function buttons.
2.Observe the correct polarity, and install 2 AAA batteries.
3.Replace the battery cover.
Note: After the batteries have been installed all the LCD's (Liquid Crystal Display) will briefly light up. Then the indoor temperature, the date as "1/ 1" and the weekday as "MON" 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

ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technol- ogy-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 Atomic Clock.
However, due to the nature of the Earth's Ionosphere, reception is very limited during daylight hours. The Atomic 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 Atomic Clock regulates the WWVB transmitter.
QUICK SET-UP GUIDE
1.Insert two AAA batteries into the Atomic 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.Mount the WS-9412U in a suitable location, where WWVB signals can be received.

"8" will appear in the hour position and the seconds will appear in the minute display. The Atomic 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 Atomic 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 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 the time zone 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 Atomic Clock. Complete programming is usually done for the initial set-up, and will require you to skip step 1 of programming sections III through VI. Wait approximately 15 seconds for the Atomic Clock to automatically return to normal operation after completing the final step.
