time, month, date, day. The remote sensor transmits the outdoor temperature. To receive the outdoor temperature,
place the sensor anywhere within 30 meters; the 433.92MHz technology means no wire installation is required.
The Atomic Clock will always be accurate to within one second as it receives daily WWVB updates. Daylight Saving
Time also automatically updates so there is no need to re-set the clock manually!
IMPORTANT: If the Atomic Clock does not receive the WWVB signal immediately, wait overnight and it will be
set in the morning.
The clock has a built in receiver that automatically synchronizes itself with the WWVB radio signal broadcast by the
US Government’s National Institute of Standards & Technology (NIST) in Fort Collins, Colorado.
