About Charging
The optical charging feature (LIGHT CHARGE) is built-in to the dial of the watch.
By frequently exposing the watch to sunlight or fluorescent light, you can continue using the watch for a long time.
Charging the watch
You can charge the watch by exposing it to light.
Make sure you use and store the watch in locations where it is easily exposed to light.
Avoid charging the watch under high temperatures as shown below.
❏ On the dashboard of a car under blazing sun
❏ Near to heating elements such as incandescent lamps and so on
❏ Locations subject to direct sunlight for extended periods that would heat up the watch
Depending on the conditions and environment for the light source, the watch may overheat causing a fire,
failure, or malfunction to occur.
Note:
Charging may take some time if the watch is not frequently exposed to light or when it is too dim, such as when it is covered by
clothes.
Also, the watch cannot charge in locations where it is not exposed to any light, such as when it is in a draw.
