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 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 main 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.

NOTE: At the time of the initial reception allow at least 24 hours for the atomic time receiver

to pick up the signal. In some cases, depending on the location, it may take up to 72 hours

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.
