Five fresh AA 1.5V alkaline batteries.2. One wall-mounting screw (optional)ABOUT WWVB (radio-controlled time)The NIST (National Institute of Standards and Technology—Time andFrequency Division) radio station, WWVB, is located in Ft. Collins, Coloradoand transmits the exact time signal continuously throughout the United States at60 kHz. The signal can be received up to 2,000 miles away through the internalantenna in the indoor weather station. However, due to the nature of the Earth’sIonosphere, reception is very limited during daylight hours. The indoor weatherstation will search for a signal every night when reception is best. The WWVBradio station derives its signal from the NIST Atomic clock in Boulder,Colorado. A team of atomic physicists continually measure every second ofevery day to an accuracy of ten billionths of a second a day. These physicistshave created an international standard, measuring a second as 9,192,631,770vibrations of a Cesium 133 atom in a vacuum.
