Start this clock at night and let the clock receive the atomic signal automatically after midnight. Always place the unit away from interfering source such as TV set, computer, metal objects and electrical appliances. Areas with access to windows are recommended for better reception.

Once the battery is installed properly, the clock automatically set itself to 12 o’clock and then receiving the signal. Once it has received the DCF signal and processed it accordingly (which takes 3 to maximum 12 minutes), the clock automatically displays the correct time.

A radio controlled clock, or "Atomic" clock, is a clock that is capable of receiving the time signal transmitted by the National Institute of Standards and Technology (NIST) in Fort Collins, Colorado.

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.

The Atomic Clock will always be accurate to within one second as it receives daily WWVB updates. Daylight Saving Time also automatically updates so there is no need to re-set the clock manually!
