User manual LA CROSS TECHNOLOGY WT-3165 QUICK START GUIDE

[. . . ] 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 atomic clock regulates the WWVB radio transmitter located in Fort Collins, Colorado, where the exact time signal is continuously broadcast throughout the United States at 60 kHz to take advantage of stable long wave radio paths found in that frequency range. Radio waves at these low frequencies use the earth and the ionosphere as a wave-guide and follow the curvature of the earth for long distances. The built in antenna system will receive the WWVB signal anywhere in North America within 2000 miles of Fort Collins where long-wave radio reception is undisturbed. [. . . ] It is not possible, however, for WWVB to penetrate most indoor shopping malls and rooms in the center of large office buildings that do not have windows. In buildings that WWVB cannot penetrate you may set the time using the manual time set button. When the clock receives the WWVB signal it will automatically set the hands to the exact time. La Crosse Technology clocks do not receive or process radio controlled time signals from Germany's DCF 77, Japan's J Ga AS, or England's MSFs atomically regulated transmitters. La Crosse Technology clocks can be manually set and used anywhere. For more information on the NIST and radio controlled time, see www. boulder. nist. gov/timefreq/ SET THE TIME USING THE MANUAL TIME SET BUTTON In some cases, the La Crosse Technology clock may not receive the WWVB signal due to atmospheric disturbances or hard to reach locations such as inside shopping malls. In this case, please use the Manual Time Set button, located at the back of the clock to manually set the time. To do this: MANUAL TIME SET BUTTON 1. 3. 4. Press and hold the Manual Set button. The second hand will move to the 12 position. Release the Manual Set button and again press and hold the Manual Set button. The minute and hour hands will fast-forward while the button is held. Keep holding the Manual Set button until the time is set as required. About 3 seconds later, the second hands will start to move and the clock is now running with manual time. Note: When the clock displays manual time, it will continue to try to receive the WWVB signal each hour. 3 TEMPERATURE AND HUMIDITY The La Crosse Technology clock has two analog sensors that measure surrounding temperature and humidity. The temperature information is displayed in degrees Fahrenheit and Celsius, and humidity data is displayed in a percentage. Humidity display in % Outer ring displays temperature in degree Fahrenheit Inner ring displays temperature in degree Celsius TROUBLESHOOTING The wonderful advantage of owning a La Crosse Technology radio controlled clock is that it is virtually trouble free. If the clock receives a clear signal it will set itself perfectly. If it does not receive a signal consider the following: Battery The La Crosse Technology clock must have a fresh battery to receive and process the time signal. Location - Try a different location, ideally near a window. It should be at least six feet from computers, TVs, air conditioners, other Radio-Controlled clocks and other electrical appliances that cause interference. Weather - Electrical storms between you and Colorado during the night will interfere with the WWVB signal. DAYLIGHT SAVING TIME The National Institute of Standards and Technology and WWVB encode a special DST "bit" in the WWVB transmission for DST. Your La Crosse Technology clock will read this information and automatically advance the hands one hour in the spring and eleven hours in the fall. ARIZONA AND HAWAII If you live in an area that does not recognize DST you must press the (unmarked) DST button for one second to deactivate your clock's DST program. To reactivate the DST program simply press the DST button again for one second. Frequently Asked Questions Q.
