User manual LA CROSSE TECHNOLOGY WT-3129B

[. . . ] 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. [. . . ] 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). [. . . ] 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.
