2.
Insert batteries observing the
correct polarity (see marking).
3.
Replace compartment cover.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis
to ensure optimum accuracy of these units.
Please participate in the preservation of the
environment. Return used batteries to an authorized
depot.

RESET
The Weather Station and the Thermo-hygro transmitter need to be reset
when one of the following conditions occur:
Unsuccessful 915 MHz signal reception.
Malfunction on the units.
Battery
replacement.
To perform a reset, remove all batteries from the units. Wait for at least 1
minute before powering up the Weather station again. Proceed from step
1 in

ABOUT 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 projection station.
However, due to the nature of the Earth’s Ionosphere, reception is very
15
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 may 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.
