[. . . ] The hour and minute hands move quickly to indicate the current time computed by the IC. English 2. The second hand moves quickly to indicate the current second, and then continues moving at one-second intervals. Notes: 1. No additional benefit is obtained by swinging the watch longer or with greater vigor. When the watch is swung, the oscillating weight in the generating system rotates to drive the mechanism. As it rotates, it gives out a sound, which is not a malfunction. q Remarks on using the time relay function 1. When using the watch for the first time after it is purchased, it is necessary to adjust the time as the watch has been adjusted to the time of the area where SEIKO's factory is located. 7 English 8 2. If the power save function has been in operation for several months before the time relay function is activated, the time indicated by the hands may include a certain amount of time loss or gain that has accumulated during those months. If the power reserve decreases to an extremely low level while the power save function is in operation, the time relay function may not be activated by swinging the watch. In this case, set the time manually, and charge the watch referring to "ENERGY DEPLETION FOREWARNING FUNCTION". HOW TO SET THE TIME 1. Pull out the crown to the second click when the second hand is at the 12 o'clock position. Push back the crown completely in accordance with a time signal. English Notes: 1. If your watch has a screw lock type crown, turn the crown counterclockwise to unscrew it, and then, pull it out. After using the crown, push it back in to the normal position, and then, turn it clockwise to screw it in completely. When setting the time, make sure that the second hand is moving at one-second intervals. When setting the minute hand, advance it 4 to 5 minutes ahead of the desired time and then turn it back to the exact minute. 9 English ENERGY DEPLETION FOREWARNING FUNCTION The watch has been charged fully at the factory, and the power save function will keep the built-in IC computing the time for up to four years. Normally, therefore, it is not necessary to charge the watch manually by swinging it. If you should find the second hand moving at two-second intervals, however, charge the watch following the procedure in "q How to charge the watch". q When the second hand starts moving at two-second intervals instead of the normal onesecond intervals, the watch will run down in approximately 12 hours. q If the second hand starts moving at two-second intervals when the power save function is turned off by swinging the watch, the power reserve may have become depleted to an extremely low level. In those cases, charge the watch following the procedure below. q How to charge the watch 1. [. . . ] If you wear the watch every day for 12 hours over a period of a week, approximately 10 days of power reserve will be secured in the KINETIC E. S. U. , which will keep the watch operating for approximately 2 months when the hands are stopped by the power save function. q Precautions for those only wearing the watch occasionally If you use the watch only occasionally, it is likely that, when you decide to use it, you will find the hands have stopped and the power save function has been activated. Before wearing the watch, be sure to use the time relay function to awaken the watch following the procedure in "How to activate the time relay function". * To use the power reserve more efficiently, it is recommended that the manual power save function be used as often as possible when you remove the watch from your wrist. REMARKS ON THE KINETIC E. S. U. q Precaution Do not pull the crown out to the second click to stop the hands with the intention of saving the energy stored in the KINETIC E. S. U. By doing so, a large amount of current flows through the built-in IC, and therefore, pulling out the crown will not save energy but actually consume more energy than usual. [. . . ]
