Important!
• Allowing the watch to become very hot can cause its liquid crystal display to go blank (totally black or
totally white, depending on the watch model). The appearance of the LCD should become normal
again when the watch returns to a lower temperature.
• Turn on the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright
light when storing it for long periods. This helps to ensure that power does not run down.
• Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Expose the watch to bright light
whenever possible.

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, leave it in a location where it
is exposed to light.
• Best charging performance is
achieved by exposing the watch to
the strongest light available.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
• The watch may enter a sleep state
(page E-19) if its face is blocked by
your sleeve even only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become particularly hot
when exposed to the conditions below for long periods.
•
On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
