ADDITIONAL EQUIPMENT (not included) 1) Two fresh 1. 5V AA batteries (optional for projection alarm clock) 2) Two fresh 1. 5V AA batteries (for remote temperature sensor) FEATURES OF PROJECTION ALARM Operation of these features is in section III 1. Radio-controlled time Projection of time and/or remote temperature EL backlight Display of indoor temperature/humidity or alarm time Indoor temperature and humidity Remote outdoor temperature Time alarm 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. [. . . ] Hold down the "MODE/MIN" button for 3 seconds, the time will flash in the Time LCD. Press and release the "SNOOZE" button twice to advance to the DST setting. "DST" will appear in the indoor temperature/humidity LCD and "ON" or "OFF" will flash in the time LCD. Press and release the "MODE/MIN" button to toggle between DST ON and OFF. . Press and release the "SNOOZE" button to confirm the DST setting and complete the set-up sequence. 7 IV. FEATURES & OPERATIONS A. Radio-controlled time Projection of time and/or remote temperature LED backlight Display of indoor temperature/humidity or alarm time Indoor temperature and humidity Remote outdoor temperature Time alarm RADIO-CONTROLLED TIME 1. The projection alarm will automatically search for the time signal upon initial set-up and every night. When the signal is being received, there will be a "tower" icon flashing to the left of the time display. When the time signal has been received successfully, the tower icon will remain steady until midnight. 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 projection alarm. Due to the nature of the Earth's Ionosphere, reception is very limited during daylight hours. The projection alarm 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, 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. This number will connect you to an automated time, announced at the top of the minute in "Coordinated Universal Time", which is also known as Greenwich Mean Time (GMT). It is possible that your projection alarm 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. When plugged into an AC outlet, the projection alarm will continuously project the time and remote temperature. When operating on batteries alone, the projection alarm will only project when the snooze button is pressed or the alarm is sounding.
