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. [. . . ] 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 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. If the symbols do not change then the weather has not changed, or the change has been slow and gradual. The EL backlight cannot be turned on constantly as this would drain the batteries and burn out the EL light. 11 F. The projection alarm measures indoor temperature with an internal sensor. This temperature is displayed in °F or °C depending on the time format (12 or 24 hour mode). The indoor temperature will take time to adjust to the surrounding temperature as the sensor is inside the case. If the remote temperature is placed next to the projection alarm more often than not the temperature will not be exact with one another. [. . . ] Problem: 1) Be sure correct time zone and daylight saving time are Solution: selected. "--. -" appears in outdoor temperature LCD Problem: 1) Check batteries in remote Solution: 2) If batteries are replaced in remote, the unit must be re-started. "OFL" appears in the outdoor temperature LCD Problem: 1) Remote temperature is out of range, move closer. 3) Interference from an outside source (cordless telephone, etc. ) 4) Contact La Crosse Technology.
