Quick set-up instructions · Install 1 fresh AA, LR6 1.5 volt ALKALINE battery. · Press a “PT”, “MT”, “CT”, or “ET” button to select a time zone. Do not press the MANUAL TIME SET button while the clock is at the 4:00, 8:00, or 12:00 position (searching for the WWVB signal). THAT’S IT! During the night your clock will automatically set itself. For a better understanding of how and why your clock works, please continue reading. Nothing is more precisely measured than time! And nothing keeps track of time more precisely and trouble-free than Skyscan radio controlled clocks. Since the beginning of time, man has been fascinated with the measurement of time and has devised accurate machines to trap and measure time. Today, time is precisely measured in the United States by the most accurate clock in North America, the Atomic Clock of the US National Institute of Standards and Technology, Time and Frequency Division in Boulder, Colorado. A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. This atomic clock regulates the WWVB radio transmitter located in Fort Collins, Colorado, where the exact time signal is continuously broadcast 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 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, Skyscan 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. MANUAL TIME SET BUTTON**ONLY use in areas with No WWVB reception |

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. 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. The time zone buttons may be pressed any time after installing the batteries. 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. Another time zone can be selected before or after the clock has set itself. Your clock can only set itself to one of the four time zones stated above. For time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set button on the back of the movement. When the battery is installed the hands will move to the 4:00, 8:00, or 12:00 o’clock position. The clock is now searching for a signal. For the initial setting it is recommended to stand the clock in an upright position near a window facing Colorado. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and search for WWVB each hour until a 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. The optimal location is near a window. Windows facing Colorado provide 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. *IMPORTANT NOTE: Only use the Manual Setting Option if, after a few days, you are absolutely unable to receive a WWVB signal. Skyscan 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. Skyscan clocks can be manually set and used anywhere. MANUAL TIME SET OPTION · Press and hold the TIME SET BUTTON on the back of the movement continuously to set the manual time. Your clock is now working as a quartz clock and not searching for the WWVB signal. It is important to not release the button for more than 2 seconds during this time, or your clock will automatically return to the RADIO CONTROL MODE to begin searching for a WWVB signal again. · If at any time your clock automatically advances to 4:00, 8:00, or 12:00, it has entered the RADIO CONTROLLED MODE and is searching for the WWVB signal.· If you are trying to manually set your clock and have accidentally returned to the RADIO CONTROL MODE, you must remove the batteries, wait 2 minutes, and then reinstall the battery. The clock will advance to 4, 8, or 12 and allow you to use the MANUAL SET BUTTON. · There are 2 ways to return to RADIO CONTROL MODE if your clock is manually set:1. Remove the battery, reinstall it after 2 minutes, and start the clock again.2. Press the MANUAL SET BUTTON for more than 3 seconds. The hands will move to the 4:00, 8:00, or 12:00 o’clock position and begin searching for a WWVB signal.Ø After successful WWVB signal is established, your clock will be set automatically and will work as a radio controlled clock.Ø If reception of WWVB signal is not possible, your clock will switch back to the QUARTZ MODE after 10 minutes and show the quartz time. This movement is now functioning as a quartz clock and will not attempt to receive the WWVB signal again, unless you remove the batteries or press the TIME SET BUTTON again as described above.· It is not possible to manually set the time if your clock has automatically set itself. For more information on the NIST and radio controlled time, see http://www.boulder.nist.gov/timefreq/ Troubleshooting The wonderful advantage of owning a Skyscan 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 Skyscan clock should have a fresh Alkaline Battery to best 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 Radio Controlled 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. Daylight Saving Time The National Institute of Standards and Technology and WWVB encode a special DST “bit” in the WWVB transmission for DST. Your Skyscan clock will read this information and automatically advance the hands one hour in the spring and eleven hours in the fall. If Congress changes the Daylight Saving Time dates, your Skyscan clock will automatically set itself to the correct time on the newly designated dates.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. To reactivate the DST program simply press the DST button again for one second.Positioning the Analog Clock:Before wall mounting, please check that the WWVB signal can be received from the desired location. To wall mounting:1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 3/16" (5mm).2. Hang the Analog clock onto the screw. Please remember to ensure it locked on the place before releasing. Frequently Asked Questions Q. How long will the battery last? A. 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. Q. Can the clock be wired to control timing circuits? A. No. Q. Why does the second hand move only once every 2 seconds? A. When the battery drops below 1.25 volts the clock indicates that it is time to change the battery by advancing the second hand in 2-second steps. The operating voltage range is 1.25 to 1.75 volts.
