Although the function can be used without charging the watch for this amount of time, the stopwatch function may quickly become unusable. Charge the watch using these times as a guide. * The required charging time slightly varies depending on the model of the watch. EN 26 Charging the battery ■ How to charge the battery Expose the dial to light to charge the watch. 4 SOLAR CHARGING FUNCTION To ensure optimal performance of the watch, make Under the following situations, the energy of the watch is sure that the watch is kept sufficiently charged at all likely to be depleted, resulting in stoppage of the watch: times. • The watch is concealed under a sleeve. • The watch is used or stored under conditions where it cannot be exposed to light for a long time. * Be careful to make sure that the watch does not get hot when it is charging. (The operating temperature range is -10°C to +60°C.) * When you first start using the watch or starting it after it stopped due to a lack of charge, charge the watch sufficiently using the table on P.26 as a guide. EN 25 About energy When the energy level is low, the stopwatch seconds hands (1/100-second, 1/10-second, second) point to the 6 o'clock position. If energy is completely depleted after that, all hands move to the 12 o'clock position and the watch stops. When the stopwatch seconds hands 4 (1/100-second, 1/10-second, second) point to the 6 o'clock position, sufficiently charge the battery. How to charge the battery → P.25 Guide to charging times → P.26 • When the stopwatch hands point to the 6 o'clock position, the stopwatch will not operate. (This is not a malfunction.) • If the energy is depleted while the stopwatch is operating, the measurement may be reset. SOLAR CHARGING FUNCTION EN 27
