User manual LA CROSS TECHNOLOGY WT-3151A QUICK START GUIDE

[. . . ] A microprocessor activates the receiver and processes the time signal from Fort Collins overnight. Through the radio signals, La Crosse Technology radio controlled clocks always keep precise time. The changeover from standard time to daylight savings time, and vice versa, takes place automatically with the same precision. Additional details To set up your clock simply install one fresh AA, LR6 ALKALINE battery. Due to the nature of long wave radio signals it is normally not possible to receive a signal during the day so it is best to install the battery late in the evening. [. . . ] If the time is manually set the clock will continue to periodically search for a signal and automatically reset the hands when the signal is received. Select a location to place your radio controlled clock where it will be at least six feet away from a TV, computer, air conditioner or other household electrical appliances. Windows facing Colorado providing the best signal. The WWVB time signal will easily penetrate Masonry and wood framed buildings. WWVB will penetrate almost every residential building and most steel buildings if they have adequate windows. 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 is exposed to 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/ 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 RadioControlled clocks and other electrical appliances that cause interference. Weather - Electrical storms between you and Colorado during the night will interfere with the WWVB signal. Although we cannot control the weather we can help you predict it (see www. lacrossetechnology. com). Daylight Savings 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 Indiana 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. [. . . ] This warranty does not cover the clock's inability to receive a signal due to interference, whatever may be the source of that interference. In addition, this warranty does not cover any defects resulting from improper use, unauthorized repairs, or faulty batteries. In the event of a warranted problem please return the clock postage prepaid to the address below. La Crosse Technology will repair or replace your clock with the same or similar model free of charge.
