Solar Charging

What is solar charging?

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

• This watch uses a special rechargeable (secondary) battery.
- The watch's battery will not charge if the watch's temperature is less than approximately -10^ (14°F) or greater than approximately 60^ (140°F).
- Over-discharge will occur if the watch is not charged within approximately three months after it stops operation due to low battery power. Charging may not be possible after over-discharge occurs.

Charging the Watch

When you are not wearing the watch, put it in a location where it is exposed to bright light.

While you are wearing the watch, make sure that its face (solar panel) is not blocked from the light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Important!

• If the second hand stops for some time after the watch is continuously exposed to light, it could mean that charging is not possible due to over-discharge. Request chargeable (secondary) battery replacement by your original retailer or authorized CASIO service center.
• Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under high-temperature conditions like the ones described below.
  On the dashboard of a vehicle parked in the sun
  Nearan incandescent light bulb or other source of heat
• Under direct sunlight or in other hot areas for long periods

Note

• Exposing the watch face to light after the battery goes dead will cause the second hand to revolve counterclockwise until it stops at second 57. This indicates charging has started.
• A fully charged watch can operate for approximately seven months without further charging. Watch operation will stop approximately 20 days after the battery goes low.
