11continuously throughout the United States at 60 kHz. The signal can be received up to 2,000miles away through the internal antenna in the Wireless Weather Station. However, due to thenature of the Earth’s Ionosphere, reception is very limited during daylight hours. The wirelessweather station will search for a signal every night when reception is best.The WWVB radio station receives the time data from the NIST Atomic clock in Boulder,Colorado. A team of atomic physicists is continually measuring every second, of every day, toan accuracy of ten billionths of a second per day. These physicists have created aninternational standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133 atomin a vacuum. For more detail, visit http://www.boulder.nist.gov/timefreq.htm. To listen to theNIST time, call (303)499-7111. This number will connect you to an automated time,announced at the top of the minute in “Coordinated Universal Time”, which is also known asGreenwich Mean Time (GMT). This time does not follow Daylight Saving Time changes. Afterthe top of the minute, a tone will sound for every second. It is possible that your wirelessweather station may not be exactly on the second due to the variance in the quartz. However,the clock will adjust the quartz timing over the course of several days to be very accurate;under 0.10 seconds per day.MANUAL SETTINGS:The following manual settings can be done in the setting mode:• LCD contrast setting• Time zone setting• Daylight saving time setting• Time reception ON/OFF setting• 12/24-Hour setting• Manual time setting• Calendar setting• °F/ °C setting• Weather forecasting icon sensitivity settingPress the SET key to advance to the setting mode:
