What is Atomic Radio Control? Atomic radio control watches are the most precise time keeping devices in the world. They keep time to the ac- curacy of more than 1 second in one million years. Until recently, the atomic watches were only found in labo- ratories and special institutions and were very large and expensive. When various governments began to broadcast atomic, electronically encoded signals with their own na- tional time, the accuracy of the atomic radio control watch became avail

What is Atomic Radio Control? Watches made to receive signals in Europe did not work in the USA or vice-versa. A different watch was needed for each time signal. This watch changes it all. It is able to receive signals transmitted by the various government locations in Figure 1: Figure 1 6

What is Atomic Radio Control? • Fort Collins, Colorado, which covers all 4 zones in the continental USA. • Anthorn, UK, that covers all of UK. • Near Frankfurt, Germany, that covers most of Western and some of Central Europe. • Kyushu Island, Japan, that covers most parts of Japan and parts of Korea. The radio receiver in the watch picks up the transmitted signal and it is decoded with a split-second precision, to synchronize to the accurate time. At the same time, the radio signal au

Replacing the Battery The watch runs on one CR2032 battery. Figure 3a Figure 3b 1. Open the back cover of the watch. (See Figure 3a.) 2. Remove the metal plate of + polarities. (See Figure 3b.) 3. Replace with CR2032 button cell, with positive pole (+) facing out. Ensure that it is retained securely in position by the metal plate. 4. Replace the back cover. 9

Replacing the Battery Notes: • Dispose of the used batteries properly, in accordance to the environmental laws in your area. • Press and hold the four buttons to reset the watch if it is operating in an unfavorable way or malfunctioning. Auto Synchronization Once the battery is installed, the receiver circuit is acti- vated. The antenna icon on the LCD blinks. (See Figure 4.) The bars facing the antenna indicate the strength of the radio signal: no bars mean there is no signal or a very

Auto Synchronization the radio signal strength indicators to find a location where the reception is strong. If the watch is too close to electrical appliances, such as a TV, mobile phone or computer, they may cause undesirable signal interference. A strong signal is normally found close to the window. (See Figure 6.) In some areas where the signal is poor, you may need to position and rotate the watch until the best signal strength is obtained. Figure 4. Figure 5. Blinking antenna icon

Auto Synchronization Once you have found the optimal position, leave the watch still so that it can receive a clear signal. It normally takes 3 to 10 minutes to synchronize. Once it is success- ful, the watch displays extremely accurate time and the correct date. A successfully synchronized watch features a non-blinking antenna icon and a radiating beacon. (See Figure .) The synchronized watch attempts to refresh itself with the radio time signal at least once a day. If it fails for mor

Auto Synchronization Radiating Beacon Symbol The watch is a radio device and, like a mobile phone or the radio, in certain locations and times of day, it may not pick up a strong enough signal to synchronize. If the watch fails to synchronize in the first attempt, it reattempts every 2 hours for the first 3 days. In most cases, the watch syn- 14

Auto Synchronization chronizes overnight as the radio signal is the strongest in the early morning. You can leave the watch to synchronize at a later time or you can set the watch manually. As noted below, a manually set watch still attempts to synchronize itself automatically every 2 hours for the first 3 days. Note: Regarding forced synchronization and halting of synchronization, if you want the watch to attempt synchro- nization, press and hold the MODE button. This activates the synch

Reading Other Data or Setting the Watch The watch normally displays the time and calendar (month, day) continuously. From this display mode, repeat- edly pushing MODE button shows the following data: Mode A = Stopwatch Display Mode B = Countdown Display Mode C = Alarm 1 Mode D = Alarm 2 Mode E = Country Selection Mode F = Offset Display 16

Reading Other Data or Setting the Watch After releasing the MODE button, the display returns to normal display in 8 seconds (when in Modes C, D, E or F). However, if you press and hold the SET/LIGHT button for 2 seconds in normal display or when in Modes B, C, D, E or F, the watch enters into Setting mode for that particular mode. To set, press the UP or DOWN button. The blink- ing digits or icons indicate the values to be adjusted. Manual Setting If necessary, or when you travel to a place
