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 the 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 set automatically, please consider the following: • During nighttime 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.

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 the 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 set
automatically, please consider the following:
• During nighttime 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.
• The atomic clock receiver is programmed that it will search for the time signal daily at 0:00,
3:00, 6:00, and 12:00 am.
• To enable or disable the atomic time receiver, press and hold UP (?
) button for 3 seconds.
If time reception is activated, a tower icon will start flashing. If reception is disabled, the
tower icon will disappear.
• If the time signal has not been received in 8 minutes, you may set the time manually.
