LONG RANGE WIRELESS COLOR WEATHER STATION 

   Owner’s Manual

Thank you for purchasing the new generation color weather station. Designed and engineered 

with the state-of-art technology and components, this instrument will provide accurate and 

reliable measurement of barometric pressure, weather forecast, in/ out humidity, temperature, 

heat index, dew point as well as atomic clock. Read this manual carefully to fully explore the 

features and functions of the new product.

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
