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
28
continuously throughout the most of the continental United States at 60 KHz
frequency. The Atomic Time Clock in your weather station 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 set automatically, please consider the following:
• During night-time hours, atmospheric disturbances are typically less
severe and radio signal reception may improve. A single daily reception
is sufficient enough to keep the clock accuracy within 1 second.
• Make sure the unit is positioned at 8 feet (2 meters) distance from any
interference source such as a TV, computer monitor, microwave, etc.
• Within concrete wall rooms such as basements or office buildings, the
received signal may be weakened. Always place the Projection Clock
near the window for better reception.
Once the atomic time signal is received, the date and time will be set
automatically, and the [
] icon will appear.
After the clock is set manually, place the main unit by the window for the better
reception. The atomic clock receiver is programmed that it will continue to
search for the atomic time signal daily for every hour between 1:00 am and
4:30 am.
Once the time signal has been successfully received, the time and date will be
updated automatically.
To enable or disable the atomic time receiver:
• Press and hold UP - if atomic time reception is activated, a triangular
