    Frequently asked questions

    What is an "atomic wall clock" and how does it work?

    An atomic wall clock contains a tiny radio receiver that picks up the longwave time signal broadcast by the National Institute of Standards and Technology (NIST) from Fort Collins, Colorado.

    This signal is linked to the world's most accurate clocks. Your clock uses this signal to automatically synchronize its own time, ensuring it is always precise to the second.

    Will this clock work in any location?

    The WWVB radio signal that the clock uses covers the entire continental United States, as well as parts of Canada and Mexico. As long as you are within this broadcast range, the atomic clock should be able to receive the signal.

    For best reception, it's recommended to place the clock near a window and away from large metal objects or other electronic devices that could cause interference.

    Do I ever need to set this clock manually?

    Initially, you may need to set the time zone. After that, the clock will automatically search for the atomic signal and set itself.

    The only time you might need to set it manually is if you are in an area with very poor reception or if you wish to override the atomic time feature, though for most users, it is completely self-setting.

    What happens if the clock loses the radio signal?

    If the atomic wall clock temporarily loses the radio signal, it will continue to run accurately as a standard, high-quality quartz clock.

    It is programmed to automatically search for the signal again at regular intervals, typically during the night when there is less atmospheric interference. Once it successfully receives the signal again, it will automatically correct itself to the perfect time if needed.
