OVERCHARGE PREVENTION FUNCTION

The solar cell underneath the dial converts light into "electrical energy” and stores the power in a secondary battery. When the secondary battery is fully charged, the overcharge prevention function is automatically activated to avoid further charging. There is no need to worry about damage caused by overcharging no matter how much the secondary battery is charged in excess of the "time required for fully charging the watch.”

*Refer to “STANDARD CHARGING TIME” on page 11 to check the time required for fully charging the watch.

POWER SOURCE

•The battery used in this watch is a special secondary battery, which is different from ordinary batteries. Unlike an ordinary silver oxide battery, the secondary battery does not require periodic replacement.

•The secondary battery is an environmentally friendly, clean energy storage device.

WARNING

(Notes on charging the watch)

When charging the watch, do not place the watch in close proximity to an intense light source such as lighting equipment for photography, spotlights or incandescent lights, as the watch may be excessively heated resulting in damage to its internal parts.

When charging the watch by exposure to direct sunlight, avoid places that easily reach high temperatures, such as a car dashboard.

Always keep the watch temperature under 60ºC.

WARNING

When replacing the secondary battery, make sure that the exclusive secondary battery for this watch is used. Installation of an ordinary silver oxide battery can generate heat that can cause bursting or ignition.

Even when a silver oxide battery is substituted, electrical continuity cannot be obtained.
