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
x
Too close to an incandescent lampx
Under direct sunlightx
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.
E-8
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-14) if
its face is blocked by your
sleeve even only partially.

completely?
Go to step 2.
The watch is charged sufficiently.
For details about charging, see
“Charging the Watch” (page E-8).

Power Recovery Mode
The watch is designed to go into a power recovery mode that stops hand operation
temporarily whenever power suddenly drops below a certain level due to overuse
of the alarm tone over a short period. Note that all operations are disabled while the
watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal
operation after power recovers (in about 15 minutes). Putting the watch in a location
where it is exposed to light will help power to recover sooner.

capability can come in handy when you frequently travel between two locations in
different time zones.

Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-11). Continue
exposing the watch to light until the
x
Second Hand starts moving normally (at one-
second intervals).
■ The
x
Second Hand starts moving at one-second intervals, but then suddenly
returns to move at two-second intervals.
The watch probably is not sufficiently charged yet. Continue keeping it exposed to
light.
E-50
■ The hands and/or day indications are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand and day alignment. Adjust the watch’s
hand and day home position alignment (page E-44).
World Time Mode
■ The World Time indicated by the
b
Left Dial Hands in the World Time Mode is
one hour off from the actual time in the selected time zone.
The STD (standard time)/DST (daylight saving time) setting of the selected World
Time City may be wrong. Select the correct STD (standard time)/DST (daylight saving
time) setting (page E-38).
■ The World Time indicated by the
b
Left Dial Hands in the World Time Mode
is off.
Your Home City setting may be wrong. Check your Home City setting and correct it, if
necessary (page E-20).
