If it doesn't work outdoors at night, it's probably best to return it for a replacement.Īll content on the WeatherShack Education Center is Copyright 2002-2020. If it works outdoors but not indoors, the problem may be interference inside the house or building.

If none of these tips have solved the problem, take the radio controlled clock outdoors at night and power it down (remove the batteries or unplug it), then power it up again to force it to look for the WWVB atomic clock synchronization signal. For example, if the clock is installed in a mobile home or a house with metal siding, radio control might not be possible. Note that the shielding of a metal building may prevent radio controlled clocks from receiving WWVB's atomic clock synch signal. They can cause interference, and some have a scan frequency at or near the WWVB carrier frequency of 60 kHz.

Locate atomic wall clocks at least 4-8 feet away from computer monitors.

Place the radio controlled clock along a wall or near a window that faces towards Fort Collins.

Atomic clocks have antennas that are directional and reception may be improved by turning the antenna to increase signal strength. If it's a wall clock, try mounting it on a wall perpendicular to the one it is currently on (if it is on a north or south wall try an east or west wall).

If the radio controlled clock is a desk top unit, try rotating it 90 degrees.

If the clock uses batteries, check them and replace if necessary.

Try powering down the clock (unplug it or remove the batteries), then turn it on again to see if it synchronizes.If you are having problems, check first to see if the atomic clock synchronization signal is being received. An analog radio controlled clock may provide an audio indication (typically a series of tones or beeps to indicate if the signal is there, accessed by pushing a button). Most atomic digital clocks have an icon in the display that indicates if the atomic clock signal is being received properly from WWVB (usually a radio tower icon). How does an atomic clock work? A radio controlled clock sold in North America is permanently set to receive and process an atomic clock synchronization signal broadcast from WWVB in Boulder, Colorado.
