Seiko CAL. 7L22 manual Remarks on the Kinetic E.S.U, Energy Depletion Forewarning Function

English

REMARKS ON THE KINETIC E.S.U.

●Do not pull the crown out to the second click with the intention of stopping the second hand just to save energy. By doing so, a large amount of current flows through the built-in IC. Therefore, pulling out the crown to the second click will not save energy but, in fact, consume more energy than usual.

CAUTION

Never install a silver oxide battery for conventional watches in place of the KINETIC E.S.U. The battery may burst, become very hot or catch fire. Even if the battery is installed, electricity will not be conducted.

ENERGY DEPLETION FOREWARNING FUNCTION

●When the second hand starts moving at two-second intervals instead of the normal one-second intervals, the watch will run down in approximately 12 hours.

*If the second hand starts moving at two-second intervals while the stopwatch is in use, the watch will run down in approximately 45 minutes assuming the stopwatch remains in use. (Refer to “HOW TO CHARGE AND START THE WATCH”.)

In this case, swing the watch from side to side to sufficiently charge the KINETIC E.S.U.
