The changeover from standard time to daylight savings time, and vice versa, takes place automatically with the same precision. Through the radio signals, our radio controlled clocks always keep precise time. A microprocessor activates the receiver and processes the time signal from Fort Collins overnight. The built in antenna system will receive the WWVB signal anywhere in North America within 2000 miles of Fort Collins where long-wave radio reception is undisturbed. Radio waves at these low frequencies use the earth and the ionosphere as a wave-guide and follow the curvature of the earth for long distances. This atomic clock regulates the WWVB radio transmitter located in Fort Collins, Colorado, where the exact time signal is continuously broadcast throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that frequency range.

These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second per day. Today, time is precisely measured in the United States by the most accurate clock in North America, the Atomic Clock of the US National Institute of Standards and Technology, Time and Frequency Division in Boulder, Colorado. Since the beginning of time, man has been fascinated with the measurement of time and has devised more accurate machines to trap and measure time.

Nothing is more precisely measured than time!Īnd nothing keeps track of time more precisely and trouble free than our radio controlled clocks. THAT’S IT! During the night your clock will automatically set itself.įor a better understanding of how and why your clock works please continue reading. Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery.We hope you will enjoy the convenience of never having to set your clock again and the confidence of knowing exactly what time it is. Welcome to the world of radio controlled timekeeping technology. We do not have any instructions for other brands outside of Howard Miller and Seiko clocks. These may or may not work for other brands. *These instructions are for the brands we offer including Howard Miller and Seiko Clocks.
