particularly hot when exposed to the following conditions for long periods.
On the dashboard of a car parked in direct sunlight
x
Too close to an incandescent lamp x
Under direct sunlight x
Important!
Keep the watch in an area normally exposed to bright light when storing it for long
x
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
x
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed 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, be sure
to leave it in a location
where it is exposed to light.
Best charging
x
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
makes sure that its face is
not blocked from light by the
sleeve of your clothing.
The watch may enter a
x
sleep state (page E-22) if
its face is blocked by your
sleeve even only partially.
