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 and date 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 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 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 information on the atomic clock
and WWVB please see the NIST website at http://www.boulder.

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid
rechargeable batteries.
1. Have the indoor weather station and remote temperature/
humidity sensor 3 to 5 feet apart.
2. Batteries should be out of both the indoor weather station
and remote temperature/humidity sensor units for 10 minutes.
3. Place the batteries into the remote temperature/humidity
sensor first then into the indoor weather station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor weather station and remote temperature/
humidity sensor will start to talk to each other and the display
will show the indoor temperature/humidity, outdoor temperature/
humidity, heat index and dew point. If the indoor weather station
does not display all information after the 15 minutes please retry
the set up as stated above. After all information has been
displayed for 15 minutes you can place your sensors outdoors
and set your time.
Important Notes on Set-up and Operation
•
The remote temperature/humidity sensor should be placed
in a dry, shaded area.
•
Fog and mist will not harm your remote temperature/humidity
sensor but direct rain must be avoided.
•
The remote temperature/humidity sensor has a range of 330

1. Three fresh AA 1.5V batteries for the indoor weather station.
2. Two fresh AA 1.5V batteries for the remote temperature/
humidity sensor.
3. One Philips screwdriver for mounting.
feet. Any walls that the signal will have to pass through will
reduce distance. An outdoor wall or window can have up to 30
feet of resistance and an interior wall can have up to 20 feet of
resistance. Your distance plus resistance should not exceed
330 ft. in a straight line.
•
The remote temperature/humidity sensor transmits a signal
every minute. After the batteries have been installed, the indoor
weather station will search for the signal for a duration of 4
minutes. If there is no temperature or humidity reading in the
OUTDOOR LCD after 4 minutes, make sure the units are within
range of each other, or repeat the battery installation procedure.
•
If a button is pressed before the indoor weather station receives
the signal from the remote temperature/humidity sensor, you
will need to follow the battery installation procedure again.
To complete the set up of your new wireless weather station after
the 15 minutes have passed please follow the steps that follow in
the Detailed Set-Up Guide.
