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 Jumbo Atomic
Clock 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 Jumbo Clock near the window for
better reception.

GETTING STARTED
BATTERY INSTALLATION
• Open the battery compartment door.
• Install 2 batteries (UM-3 or "AA" size 1.5V)
matching the polarity as shown in the battery
compartment.
• Replace the battery compartment door.
ATOMIC CLOCK
Immediately after batteries are installed, the atomic
time signal receiver will start to search for the time
signal. It usually takes between 5-8 minutes.
Once the atomic time signal is received, the date and
time will be set automatically, and the [ ] icon will
appear. If the time signal has not been received in 8
minutes, press MODE button to set the time and date
manually. After the clock is set manually, place it by
the window for the better reception. The atomic clock
receiver is rogrammed 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.
CALENDAR AND CLOCK DISPLAY MODES
Precise time is displayed in hour-minutes-seconds
format on the top line of the Jumbo Clock.
The date is displayed in month-date format on the
bottom line next to the day of the week.
