• Malfunction on the units.
• Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1 minute
before powering up the Weather station again. Proceed from step 1 in
“Setting Up”

ATOMIC TIME - WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology—Time and
Frequency Division) WWVB radio station is located in Ft. Collins, Colorado,
and transmits the exact time signal continuously throughout the United
States at 60 kHz. The signal can be received up to 2,000 miles away
through the internal antenna in the Weather Station. However, due to the
nature of the Earth’s Ionosphere, reception is very limited during daylight
hours. The wireless weather station will search for a signal every night
when reception is best.
The WWVB radio station receives the time data from the NIST Atomic clock
in Boulder, Colorado. A team of atomic physicists is continually measuring
every second, of every day, to an accuracy of ten billionths of a second per
day. These physicists have created an international standard, measuring a
second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum.
For more detail, visit http://www.boulder.nist.gov/timefreq.htm. To listen to
the NIST time, call (303)499-7111. This number will connect you to an
automated time, announced at the top of the minute in “Coordinated
Universal Time”, which is also known as Greenwich Mean Time (GMT).
This time does not follow Daylight Saving Time changes. After the top of
the minute, a tone will sound for every second. It is possible that your
wireless weather station will not be exactly on the second due to the
variance in the quartz. However, the clock will adjust the quartz timing over
the course of several days to be very accurate; under 0.10 seconds per
day.
