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
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.
QUICK SET-UP GUIDE
1. Insert two AAA batteries into the Remote Control Sender.
2. Insert two AA batteries into the WEATHER STATION.
3. Wait 5 minutes, or until the outdoor temperature is displayed in the
OUTDOOR LCD (Liquid Crystal Display).
4. Wait 6-10 minutes (in ideal reception conditions) for the WWVB time
to be displayed in the TIME LCD. If the WWVB takes longer to set,
you may manually set the time (see complete instructions), or you can
wait until after the weather station conducts its programmed search at
the ideal reception time period of 12:00 am to 6:00 am.
5. Mount the units, ensuring that all units are sending and receiving
signals.
Note: The Remote Control Sender transmits a signal every 3 minutes; after
the batteries have been installed, the 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.
