ADDITIONAL EQUIPMENT (not included) 1) Three fresh 1. 5V AA batteries (optional for alarm clock) 2) Two fresh 1. 5V AA batteries (for remote transmitter) 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. The signal can be received up to 2, 000 miles away through the internal antenna in the projection alarm. [. . . ] Press and release the "SET" button to confirm the 12/24-hour time display, and to return to normal operation. III. Radio-controlled time and date Projection of time and/or remote temperature Forecast icon based on changing air pressure EL backlight 7 5. 9. Six modes of date/seconds/temperature display Indoor temperature Remote outdoor temperature Dual alarms Adjustable snooze B. 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. Projection of Time and/or Remote Temperature When plugged into an AC outlet the projection alarm can continuously project the time and/or remote temperature. When operating on batteries alone the projection alarm will only project when a button is pressed. The projection will auto-focus for display from three to six feet away. The icons change in order, from "sunny" to "partly sunny" to "cloudy" or the reverse. It will not change from "sunny" directly to "rainy", although it is possible for the change to occur quickly. [. . . ] Do not use solvents or scouring agents--they may mark and damage the displays and casings. Immediately remove all low powered batteries to avoid leakage and damage. TROUBLESHOOTING The projection is faint Problem: 1) Change intensity setting Solution: 2) Use AC adapter 3) Darken surroundings 4) Use fresh batteries (if AC is not used) The LCD is faint. Problem: 1) Move unit to an area with warmer or cooler surrounding Solution: temperature. [. . . ]
