Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal has a range of up to 2,000 miles. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic clock will search for a signal every night when reception is best. . The clock receives the time signal via its built-in antenna and adjusts automatically to the selected time zone. Once the correct time is set, the clock continues running with an internal quartz-controlled mechanism. . The internal quartz-mechanism is very accurate; therefore, it does not matter if the clock is occasionally, unable to receive the time signals. When the tower icon flashes, but does not set the time or the WWVB tower does not appear at all, take note of the following: . Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 6 feet (2 meters). . Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/ or point its front or back towards the Fort Collins, Colorado, transmitter. . During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second. Note: On rare occasions, the atomic clock is not able to detect the WWVB- signal (disturbances, transmitting distance, etc.); the time can be manually set. TIME SET: First set the Time Zone. TIME ZONE: This clock has four Time Zones. E-Eastern time, C- Central Time, M- Mountain Time, or P-Pacific Time. Hold the 12/24 button for 5 seconds to change a time zone. Release then hold the 12/24 button again to change the time zone a second time. . HOUR: From normal display hold the MODE/SET button for 5 seconds and the hour will flash. Press and release the PLUS button or the MINUS button to adjust the hour. Press and release the MODE/SET button to confirm and continue to the next menu item. . MINUTES: The minutes will flash. Press and release the PLUS button or the MINUS button to adjust the minutes. Press and release the MODE/SET button to confirm and continue to the next menu item. . SECONDS: The seconds will flash. Press and release the PLUS button or the MINUS button to adjust the seconds. Press and release the MODE/SET button to confirm and continue to the next menu item. . YEAR: The year will flash. Press and release the PLUS button or the MINUS button to adjust the year. Press and release the MODE/SET button to confirm and continue to the next menu item. . DATE FORMAT: M and D will flash by the date. Press and release the PLUS button or the MINUS button to select the date displayed in Month/Day or Day/Month format. Press and release the MODE/SET button to confirm and continue to the next menu item. . MONTH: The month will flash. Press and release the PLUS button or the MINUS button to adjus...
