Module No. 3554
Solar Charging
Power generated by the solar panel powers watch operations and also is used to charge a rechargeable (secondary) battery. The solar panel is integrated into the LCD of the watch, and power for charging is generated whenever the face is exposed to light.
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 LCD (solar panel) is not blocked from light by the sleeve of your clothing. Power generation efficiency is reduced even when the LCD is blocked only partially.
Important!
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
Near an incandescent light bulb or other source of heat
Under direct sunlight or in other hot areas for long periods
