1. United States clientele WWVB The WWVB is an AM radio station in Ft Collins Colorado managed by the NIST The WWVB s function is to broadcast time of day information derived from the NIST atomic clock located in Boulder Colorado ATOMIC CLOCK An atomic clock is an extremely accurate time device measuring time by the movements of electrons in cesium atoms The NIST atomic clock is one of the most precise clocks in the world accurate to 10 billionths of one second The NIST s atomic clock contributes to the international group of clocks calculating the Coordinated Universal Time UTC the official world time RADIO CONTROLLED TIME A radio controlled time device is often confused with an atomic clock However a radio controlled time device receives its time information from the atomic clock each day through an internal antenna The radio controlled time device searches for an exact time signal every night when the signal from the WWVB is the strongest The signal can be received up to 2 000 miles away through a radio controlled time device LCD LCD is an acronym for Liquid Crystal Display This is a common type of display screen used in televisions computers watches and digital clocks CELSIUS C Celsius is metric system s unit of measurement used to calculate temperature FAHRENHEIT F Fahrenheit is the common unit of measurement used to calculate temperature in the United States For more infor2. diagram on LCD2 The phase display will change approximately every 2 days 11 hours Whenever the date or time is changed manually the radio controlled clock will display the updated moon phase within a few minutes 12 stages of the moon s phases are represented OOOO 9 New Moon Small Waxing Large Waxing First Quarter Small Waxing Large Waxing Crescent Crescent Gibbous Gibbous FullMoon Large Waning Small Waning Last Quarter Large Waning Small Waning Gibbous Gibbous Crescent Crescent Note The moon phase visible in the sky is noted by a darkening of the LCD screen Therfore a full moon is a complete dark circle MANUAL SETTINGS Note If the radio controlled clock has already successfully received the WWVB time signal and displays the correct time and date then the Manual settings can be skipped After completion of the above described procedures in Setting up the manual setting modes can be entered by pressing and holding the SET key for 3 seconds The following settings can now be programmed Time zone setting DST ON OFF Language display setting Manual time setting Year setting Month setting Date setting Weekday setting 12 24 hour time display setting C or F temperature setting TIME ZONE SETTING After entering the manual setting mode as described above the time zone can be set using the number of hours different from Greenwich Mean Time GMT range in LCD2 To do this Ts 457 T5 EST 1 The
