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 sta-
tion derives its signal from the NIST Atomic clock in Boulder, Colorado.
A team of atomic physicists continually measure every second of ev-
ery day to an accuracy of ten billionths of a second a day. These
physicists have created an international standard, measuring a sec-
ond as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum.

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable
batteries.
1. Have the indoor weather station and remote temperature sensor 3
to 5 apart.
2. Batteries should be out of both units for 15 minutes.
3. Place the batteries into the remote temperature sensor first then
into the indoor weather station.
(All remote temperature sensors must be started before the indoor
weather station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor weather station and remote temperature 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.
If the indoor weather station does not display all values after the 15
minutes please retry the set up as stated above. After all values are
displayed for 15 minutes you can place your remote temperature sen-
sor outdoors and set your time.
The remote temperature sensor should be placed in a dry, shaded
area. The remote temperature sensor has a range of 330 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 330 ft. in a straight line.
NOTE: Fog and mist will not harm your remote temperature sensor
but direct rain must be avoided.
To complete the set up of your indoor weather station after the 15
minutes have passed please follow the steps in the Detailed Set Up
Guide.
Note: The remote temperature sensor transmits a signal every 3
minutes; after the batteries have been installed, the indoor weather
station will search for the signal for a duration of 5 minutes. If there is
no temperature reading in the OUTDOOR LCD after 5 minutes, make
sure the units are within range of each other, or repeat the battery
installation procedure.
