Atomic Analog/Digital Wall Clock
Model 27011-SKYSCAN
Instruction Manual
RADIO CONTROL FEATURE
The National Institute of Standards and Technology (NIST) is located in Fort Collins, Colorado. The NIST continuously
broadcasts the time signal (WWVB, 60 KHz) which can be received anywhere in the continental United States where long
wave (AM) radio reception is possible. The signal can reach approximately 2,000 miles. However, due to the nature of the
Earth’s atmosphere, reception is very limited during the daylight hours. This clock will search for the Atomic signal every
night when reception is optimal.
The WWVB radio station delivers its signal from the NIST Atomic Clock in Boulder Colorado
POSSIBLE RECEPTION-INTERFERING SOURCES
All radio-receivers of the atomic clock may be subject to certain interferences. Interferences can be caused for example by
a thunderstorm or metallic elements in buildings (such as-windows with a metal frame). Also, domestic appliances, as well
as TV sets and PCs, can interfere with the reception.
If your clock cannot receive the WWVB Atomic signal, change the location of the clock near a window
