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 projection alarm.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The projection alarm 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 about WWVB please see the NIST
website at

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor station and outdoor remote 3 to 5 apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the outdoor remote first then into the indoor station.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the outdoor remote first then into the indoor station.
(All outdoor remotes must be started before the indoor station)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the display and sensor will start to talk to each other and the display will
show both the indoor temperature and an outdoor temperature. If the station does not
display both temperatures after the 10 minutes please retry the set up as stated above.
After both indoor and outdoor temperatures are displayed for 10 minutes you can place
your sensor outdoors and set your time.
The remote sensor should be placed in a dry, shaded area. The remote 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.
