WWVB Atomic Time
The NIST radio station, WWVB, is located at Ft. Collins, Colorado and
transmits the exact time signal continuously throughout North America at
60 kHz. The signal has a range of up to 2,000 miles. Please note, due to the
nature of the Earth's Ionosphere, reception is limited during daylight hours.
The atomic clock will search for a signal every night when reception is better.
The clock receives the time signal via its built-in antenna and adjusts
automatically to the selected time zone. Once the correct time is set, the
clock continues running with an internal quartz-controlled mechanism.
The internal quartz-mechanism is very accurate; therefore, it does not matter
if the clock is occasionally unable to receive the time signals.
Environmental reception effects
Your atomic clock obtains the accurate time with wireless technology. As
with all wireless devices, the connection may be affected by the following
circumstances:
Long transmitting distance
•
Nearby mountains and valleys
•
Among tall buildings
•
Near railway, high voltage cable etc.
•
Near freeway, airport, etc.
•
Near construction site
•
Inside concrete buildings
•
Near electrical appliances
•
Near computers and TV's
•
Inside moving vehicles
•
Near metallic structures
