[. . . ] From here the exact time signal is continuously broadcasted 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 in your clock will receive the WWVB signal anywhere in North America within 2000 miles of Fort Collins where long-wave radio reception is undisturbed. A microprocessor activates the receiver and processes the time signal from Fort Collins overnight. [. . . ] La Crosse Technology® atomic clocks can be manually set and used anywhere. Please Note: WWVB time will over ride a manual setting. For more information on the NIST and radio controlled time, see www. boulder. nist. gov/timefreq/. Once the clock has received the WWVB signal, press the time zone button to select your time zone. If you are in the Pacific Time Zone, no change is needed and you are ready to hang your clock. If you are not in the Pacific Time Zone, select your time zone by pressing one of the four time zone buttons PT-Pacific Time, MT-Mountain Time, CT-Central Time, ET-Eastern Time and holding this button down for 5 seconds. If multiple buttons are pressed, the clock will set to the time zone selected last. If no time zone is selected the clock will default to Pacific Time. If you live in an area that does not 1 Notes: The minutes and seconds of the digital clock cannot be manually set. It will receive the WWVB time from the analog clock. The time format is fixed to "12-hr" time display. "PM" will be shown in hours from noon to midnight. The calendar will also be updated once the WWVB signal from the analog clock has been received. ARIZONA 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. Will the digital World Time display also set ahead or back one hour for DST?Yes, if you have DST set to "ON". (By default DST is set to "ON". ) If the digital World Time display is set to a foreign time zone for a country that has not adopted the same DST dates, you will need to manually set the LCD. A good AA alkaline battery will last over one year. If your clock is located in an area with little interference where it can quickly receive a signal the battery can last much longer than one year. Can this La Crosse Technology® clock be used outdoors?Outdoor use is not recommended for this clock. Can the La Crosse Technology® atomic clock be wired to control timing circuits?No. neglect (including the lack of reasonable and necessary maintenance); (2) damage occurring during shipment (claims must be presented to the carrier); (3) damage to, or deterioration of, any accessory or decorative surface; (4) damage resulting from failure to follow instructions contained in your owner's manual; (5) damage resulting from the performance of repairs or alterations by someone other than an authorized La Crosse Technology®, Ltd authorized service center; (6) units used for other than home use (7) applications and uses that this product was not intended or (8) the products inability to receive a signal due to any source of interference.
