ABOUT WWVB (radio-controlled time)
The NIST (National Institute of Standards and Technology-Time and Frequency Division) radio station,
WWVB, 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 indoor weather station. However, due to the nature of the Earth's Ionosphere, reception
is very limited during daylight hours. The indoor weather station will search for a signal every night
when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in
Boulder, Colorado. A team of atomic physicists continually measure every second of every day to an
accuracy of ten billionths of a second a 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
information about WWVB please see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm
QUICK SET-UP GUIDE
Hint : Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor weather station and remote thermo/hygro sensor 3 to 5 apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote thermo/hygro sensor first then into the indoor weather station.
(All remote thermo/hygro sensors must be started before the indoor weather station)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the indoor weather station and remote thermo/hygro sensor will start to talk to each other
and the indoor weather station will show both the indoor temperature and humidity and the outdoor
temperature and humidity. If the indoor weather station does not display all values after the 10
minutes please retry the set up as stated above. After all values are displayed for 10 minutes you can
place your remote thermo/hygro sensor outdoors and set your time.
The remote thermo/hygro sensor should be placed in a dry, shaded area. The remote thermo/hygro
sensor has a range of 80 feet. Any walls that the signal will have to pass through will reduce distance.
An outdoor wall or window will have 20 to 30 feet of resistance and an interior wall will have 10 to 20
feet of resistance. Your distance plus resistance should not exceed 80 ft. in a straight line.
