[. . . ] 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. Through the radio signals, La Crosse Technology® atomic clocks always keep precise time. [. . . ] Wait for the digital clock to receive the WWVB time and date from the analog clock. Then the digital clock will start normal runs. BATTERY COMPARTMENT COVER DISPLAY KEY TIME SET KEY (FOR WORLD TIME) BATTERY COMPARTMENT Once the battery is installed, the clock will begin searching for a signal. For the initial setting, it is recommended to stand the clock in an upright position near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time (for the default Pacific Time Zone), or it will determine that the signal is not receivable at its current location and time of day. The clock will fast-forward the hands to the 4, 8, or 12 o'clock position immediately and search for WWVB at a specific time until a signal is received. Note: 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. La Crosse Technology® atomic 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® atomic clocks can be manually set and used anywhere. 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 you live in an area that does not 1 Notes: The minutes and seconds of the digital clock cannot be manually set. 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?(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. 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 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.
