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-6002U 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

function buttons.

2) Observe the correct 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 “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 “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

Battery Compartment

Battery Cover

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 “-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-up, and will require you to skip step 1 of

programming sections III through VIII. Wait approximately 15

seconds for the Atomic Clock to automatically return to normal

operation.

I) FUNCTION BUTTONS

There are 2 function buttons located on the backside of the

Atomic Clock. The function buttons are labeled: SET and +.

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”.

MOUNTING

There are two possible ways to mount the atomic clock:

•use of the foldout table stand, or

•wall mounting.

I) FOLDOUT TABLE STAND

The foldout table stand leg is located on the backside of the atomic

clock. The hinge is towards the center of the atomic clock, and the

end (with no hinge) needs to be folded in towards the center. Once

the foldout table stand is extended, place the atomic clock in an

appropriate location.
