![]() ![]() Due to the nature of long wave radio signals it is normally not possible to receive a signal during the day so it is best to install the battery late in the evening. To set up your clock simply install one fresh AA, LR6 ALKALINE battery. 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. Use the built-in auxiliary input to listen to music from an external audio source.Īn integrated USB charging port allows your smart phone or device to recharge without using an additional outlet.*These instructions are for the brands we offer including Howard Miller and Seiko Clocks. Wake up to your favourite radio stations or wake up tone. Connectivity & PlaybackĮnjoy listening to your favourite radio station or music through Bluetooth. The clock can be set with the surrounding bezel, while clock set, snooze and sleep timer are set with just a push of a button. One knob for your power source, one knob for volume, one 5:1 ratio tuning dial to help you bring in even the weakest stations. Simple hands-on controls to deliver exactly what you want. A heavy-magnet long-throw driver is mated to a frequency contouring circuit that automatically adjusts output over half-octave increments, resulting in musically accurate tonal balance and bass response. This single top-firing mono speaker delivers the true art form of analog audio. The clock was designed for easy setup and use, which is lightly illuminated, so you can see it at night. The Model Three BT brings all the style and sound of the analog driven Model One® perfectly into the bedroom with the addition of a classic analog clock.
