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
performance is achieved
by exposing the watch to
light that is as strong as
possible.

Power Levels
You can get an idea of the watch's power level by
observing the movement of the x Second Hand in the
Timekeeping Mode.
If the x Second Hand is moving normally at one-second
intervals, power is at Level 1.
If the x Second Hand is moving at two-second intervals,
power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.
Moves at two-second
intervals.

YES
The watch is charged suffi ciently.
For details about charging, see
"Charging the Watch" (page E-16).
NEXT
Go to step 2.
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
sleep state (page E-22) if
its face is blocked by your
sleeve even only partially.
2. Check the Home City and the daylight saving time (DST) settings.
Use the procedure under "To confi gure Home City settings" (page E-32) to confi gure
your Home City and daylight saving time settings.
3. Set the current time.
See "Confi guring Current Time and Date Settings" (page E-38).
The watch is now ready for use.

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 following conditions for long periods.
On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp
Under direct sunlight
Important!
Keep the watch 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.
Make sure that the watch is exposed to bright light whenever possible.
Level Hand Movement

Normal.
x x Second Hand moves at two-second intervals.

n n Day changes to 1 (home position).
x x Second Hand stopped.
z z Hour Hand and c c Minute Hand stopped at

12 o'clock.
When power drops to Level 3, all functions will be disabled but the watch will
continue to keep time internally for about one week. If you recharge the battery
suffi ciently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
A short while after exposing the watch to light after its battery charge has run down
will cause the x x Second Hand to move counterclockwise until it stops at second 57
on the face. This indicates that charging has started. See page E-21 for information
about required charging times.
