GUIDELINE OF CHARGING TIME/ACCURACY English V176 u The watch operates while charging electricity by Environment/Lightsource (lux) A (minutes) B (hours) C (hours) converting light received on the dial to electrical energy. It cannot properly operate unless the remaining energy General offices/ Fluorescent light (700) 150 60 - is sufficient. Place or store the watch in a location receiving light etc., to 30W20cm/ Fluorescent light (3000) 33 13 110 sufficiently charge electricity. • When the watch is Cloudy weather/Sunlight (10000) 9 3.5 30 stopped or the second hand starts moving at 2-second intervals, Fair weather/Sunlight (100000) 2 0.6 5 charge the watch by exposing it to light. Expected life per charge from full charge to stoppage 6 months Loss/gain (monthly rate) Less than 15 seconds when the watch is worn on your wrist at a normal temperature range (5 ºC to 35 ºC) Operational temperature range -10 ºC to 60 ºC A: Time to charge 1 day of power B: Time required for steady operation 16 C: Time required for full charge v The above table provides only a general guideline. • The time required for charging the watch varies depending on the calibres. Check the calibre of your watch engraved on the back cover. • It is recommended that the watch be charged for as long as the charging time "B" to assure the stable movement of the watch. ENERGY DEPLETION FOREWARNING FUNCTION ● 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 1-second intervals. The watch remains accurate even while the second hand is moving at 2-second intervals. ● While the second hand is moving at 2-second intervals, the stopwatch cannot be activated. ● If the second hand starts to move at 2-second intervals while the stopwatch is operating, the stopwatch will be automatically stopped and the stopwatch hands will return to the "0" position. ● When this occurs, recharge the watch as soon as possible by exposing it to light. Otherwise, the watch may stop operating in a few days. (For recharging the watch, see "HOW TO CHARGE AND START THE WATCH") v TO PREVENT THE ENERGY DEPLETION • When wearing the watch, make sure that the watch is not covered by clothing. • When the watch is not in use, leave it in a bright place as long as possible. 17 English
