Atomic Time Reception

The radio controlled clock will automatically search for, and synchronize to, the NIST (National

Institute of Standards and Technology) Atomic clock signal transmitted at 60 KHz from Colorado.
It synchronizes the weather station clock with a precise time signal that is transmitted

continuously throughout the entire continental United States.
The WWVB tower icon flashes on the display, during intervals when the WWVB radio signal is

being received.

• 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 unit 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.
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 tower icon will start

flashing next to the clock icon. If reception is disabled, the triangular tower icon will disappear.
