CLOCK WINDOW
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology)
radio station (WWVB) is located in Ft. Collins, Colorado.
It transmits an exact time signal continuously throughout
most of the continental United States at 60 KHz frequency.
The main unit can receive this WWVB signal through
the internal antenna from up to 2,000 miles away. Due
to the nature of the Earth’s ionosphere, reception can
be limited during the daylight hours. The radio controlled
clock will search for an alternate station that receives the
atomic time signal from the NIST Atomic clock in Boulder,
Colorado.
The WWVB tower icon on the unit’s display will flash
indicating a radio signal reception from the WWVB station.
If the tower icon is not fully lit, or if the time and date are
not MODE automatically, please consider the following:
