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 clock. However, due
to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours.
The 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. For more information about WWVB please see the NIST website at

DETAILED SET UP GUIDE
1. Battery Installation
There are two locations for batteries on the clock
a. The analog clock requires one AA battery for operation
b. The battery is inserted on the back of the clock above the four time zone
buttons.
c. After the battery is inserted press the desired time zone button.
d. The weather LCD requires two AAA batteries for operation.

2. Function Keys
There are six buttons on the back of the clock.
a. The time zone buttons are labeled “PT”, “MT”, “CT” and “ET”. These
buttons are directly above the AA battery slot for the clock.
b. In between the “CT” and “ET” buttons is the DST (Daylight Saving
Time) over ride button. Pressing this button will disable/enable the DST
recognition of the clock
c. There is a black manual time set button located directly above the AA
battery slot for the clock. By holding this button down you are able to
manually set the time on your clock.
d. The last button is the “SET ºC/ºF” button, which is located below the
AAA battery compartment. Press and release this button to switch
between ºC and ºF.
3. Time Zone Setting
Press and release one of the four time zone buttons on the back of the clock to
select your desired time zone. The clock will automatically adjust to the correct
time for that zone.
4. Daylight Saving Time (DST) Setting
Press and release the daylight saving time button to deactivate or reactivate the
daylight saving time recognition feature of the clock.
Note: Some locations (Arizona and parts of Indiana) do not follow Daylight
Saving Time.
There is no indication of the mode the daylight saving time feature is in the
factory setting is ON.
