If the watch is not charged for the time specified in the column, the second hand may temporarily move at 1-second intervals. However, as it will soon resume moving at 2-second intervals, you should charge the watch for more than the specified period. English ENERGY DEPLETION FOREWARNING FUNCTION q When the energy stored in the rechargeable battery is reduced to an extremely low level, the second hand starts moving at 2-second intervals instead of the normal 1second intervals. q In that case, recharge the watch as soon as possible by exposing it to light. Otherwise, the watch may stop operating in about 3 days. TO PREVENT THE ENERGY DEPLETION q Wear the watch so that it is not covered by your clothes. q When the watch is not in use, leave it in a bright place as long as possible. NOTE ON POWER SUPPLY q This watch is provided with a rechargeable battery. Unlike conventional batterypowered watches, therefore, battery replacement is not necessary. q The solar cell is an energy source that has less adverse effect on the natural environment than conventional batteries. 7 TIME/CALENDAR SETTING English 1 Set the previous day's date. 2 Turn the hands until the desired date appears. 3 Set the hands to the desired time. 4 Push back the crown completely. 1 « 2 « 4 b c 2 3 a 8 « NOTES FOR USING THE WATCH English HOW TO CHARGE AND START THE WATCH CAUTION Caution for charging q When charging the watch, do not place it too close to a photoflash bulb, spotlight, incandescent light or other light sources as the watch temperature may become extremely high, causing damage to the parts inside the watch. q When exposing the watch to sunlight to charge it, do not leave it on the dashboard of a car, etc. q While charging the watch, make sure the watch temperature does not exceed 60 C. q When the instant-start function is activated by exposing the watch to light, the second hand starts moving at 2-second intervals immediately, but the energy stored in the rechargeable battery is not sufficient. If the watch is turned away from the light source, it may stop operating. It is important, however, to charge the watch sufficiently, especially in case of initial charge. NOTE ON POWER SUPPLY CAUTION q Never insert a conventional silver oxide battery in your watch as it may explode, generate an intense heat or catch fire. The watch is so designed that even if a conventional battery is installed in the watch, the watch will not operate. 9 TIME/CALENDER SETTING English 10 q Do not set the date between 9:00 p. m. If it is necessary to set the date during that time period, first change the time to any time outside it, set the date and then reset the correct time.
