To maximize the life of the battery keep the radio connected to a ‘live’AC outlet at all times. You will note that this system is equipped with a polarized AC power plug having one blade wider than the other. This is a safety feature. If this plug does not fit into your existing AC outlet, do not try to defeat this safety feature by filing the wide blade to make it fit into your outlet. If this plug will not fit into your outlet, you probably have an out-dated non-polarized AC outlet. You should have your outlet changed by a qualified licensed electrician. 4 AC Plug AC Outlet CKA1100_drafts052102.p65 4 21/5/2002, 15:19 BATTERY BACK-UP SYSTEM This model includes a battery back-up system that will maintain your time and alarm settings in the event of a temporary power interruption. If power is interrupted the display will go ‘Off’, but the batteries will continue to power the clock. When power is restored the display will come ‘On’ again and your time and alarm settings will be correct. The battery back-up system requires 2 “AA” batteries, not included. We recommend that you use a well-known brand of alkaline batteries for longest life and best performance. The life of the batteries is affected by the frequency and length of the power interruptions that occur in your home. For best results we recommend changing the batteries every 12 months. There is also a “BATT. LOW” indicator on the front panel that will warn you when the batteries are getting weak and need to be replaced. To install or replace the batteries: 1.) Place the radio face down. We suggest you place a towel or similar soft cloth under the radio to avoid scratching the front lens. 2.) Remove the battery door by pressing down on the tab as illustrated. 3.) Insert 2 “AA” alkaline batteries into the compartment as illustrated. 4.) Replace the battery door and place the radio right side up. If there are no back-up batteries installed, or the back-up batteries are exhausted, and you experience a power interruption the time and alarm settings will be lost. Although the time will be reset automatically the next time the Atomic Clock signal is received, the alarm times must be reset manually. We recommend that you change the batteries as soon as you notice the BATT. LOW indicator is ‘On’, and after changing the batteries check and adjust the alarm time settings if necessary. 5 CKA1100_drafts052102.p65 5 21/5/2002, 15:19 LOCATION OF CONTROLS AND INDICATORS Top Panel 30 1 2 3 4 5 6 7 8 9 10 11 12 13 18 19 20 21 22 23 24 Front Panel 25 17 26 16 27 15 28 14 29 1.)

This station is operated by the National Institute of Standards and Technology (NIST) and is located near Fort Collins, Colorado at latitude 40°40’28.3”N and longitude 105°02’39.5”W. The time signal is broadcast continuously on the long wave band at a transmission frequency of 60kHz. • Although the signal can be received anywhere in the continental United States, the southern portions of Canada and the northern portions of Mexico, the greater the distance from Fort Collins, the weaker the signal becomes. The most difficult area for reception is the northeastern coastal region of the USA. In addition to the distance from Fort Collins there is also a high level of interference in this area. This area is also in range of station MSF in Teddington, Middlesex, England. Station MSF is also transmitting at 60kHz and the signal from this station can interfere with signal from station WWVB, especially in the area from Maine to New York. • Automatic time setting is never instantaneous, even if your home was located next door to the transmitter. The Atomic Clock time signal consists of a ‘stream’ of information that normally takes between two and three minutes to receive and be decoded before the clock in this radio can set itself. Also if the signal is subjected to interference during reception the clo...
