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 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 AA 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-6003U 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) ATOMIC CLOCK
1)	Remove the battery			cover, located on the backside of the
	unit and directly above			the function buttons.
2)	Observe the correct		Battery Cover	polarity, and install 2 AA 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	SET		“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	Battery Compartment		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 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.

enter the Program Mode hold down the “SET” button for 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 Atomic Clock. Complete programming is usually done for the initial set-

I)FUNCTION BUTTONS

There are 2 function buttons located on the backside of the Atomic Clock. The function buttons are labeled: SET and +.

II)TIME ZONE SETTING

1)Hold down the “SET” button for 2 seconds, the default setting “-5EST” will flash in the Date LCD.

2)Press and release the “+” button to select the appropriate time zone. There are 13 time zones to choose from:

-5EST	Eastern Time (default setting)
-6CST	Central Time
-7MST	Mountain Time
-8PST	Pacific Time
-9ALA	Alaskan Time
-10HAW	Hawaiian Time
-11
-12
GMT	Greenwich Mean Time
-1
-2
-3
-4ATL	Atlantic Time

3)Press and release the “SET” button to confirm the time zone setting, and to advance to DST (Daylight saving time) setting.

III)DST (DAYLIGHT SAVING TIME) SETTING

Note: The DST default is “On”, meaning that the WWVB will automatically change the time according to Daylight Saving Time in the spring and fall. For areas that do not recognize DST changes (Arizona and parts of Indiana) turn the DST “OFF”.

1)Hold down the “SET” button for 2 seconds (the selected time zone will flash), press the “SET” button once more until “On” flashes in the time LCD and “DST” flashes where the Weekday normally appears.

2)Press and release the “+” button to turn the DST off, as will be indicated by the display of “OFF” in the time LCD.
