to move at high speed, even if you release the button. High-speed hand
movement will continue until you press either button. High-speed hand
movement started with the
D
button will also stop automatically after 12
revolutions, while one started with the
B
button will stop automatically after
one revolution.

Power Supply
This watch is equipped with a solar panel and a rechargeable battery that is charged
by the electrical power produced by the solar panel. The illustration shown below
shows how you should position the watch for charging.
Example:
Orient the watch so its face is
pointing at a light source.
•
The illustration shows how to position a
watch with a resin band.
•
Note that charging effi ciency drops
when any part of the solar panel is
blocked by clothing, etc.
•
You should try to keep the watch outside
of your sleeve as much as possible.
Charging is reduced signifi cantly if the
face is covered only partially.

Important!
•
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 rechargeable battery
power to run down. Be sure that the watch is exposed to bright light whenever
possible.
•
This watch uses a rechargeable battery to store power produced by the solar
panel, so regular battery replacement is not required. However, after very long use,
the rechargeable battery may lose its ability to achieve a full charge. If you
experience problems getting the rechargeable battery to charge fully, contact your
dealer or CASIO distributor about having it replaced.
•
Never try to remove or replace the watch’s rechargeable battery yourself. Use of
the wrong type of battery can damage the watch.
•
The current time and all other settings return to their initial factory defaults whenever
battery power drops to Level 5 (pages E-54 and E-55) and when you have the
battery replaced.
•
Turn on the watch’s Power Saving function (page E-60) and keep it in an area
normally exposed to bright light when storing it for long periods. This helps to keep
the rechargeable battery from going dead.
E-53
To check the current battery level
In the Timekeeping Mode, press
&
to display the battery level indicator (page E-8).

The battery level indicator shows you the current power level of the rechargeable
battery.

•
The fl ashing
indicator at Level 3 and the fl ashing charge indicator (
C
) at Level
4 tell you that battery power is very low, and that exposure to bright light for
charging is required as soon as possible.
•
At Level 5, all functions are disabled and settings return to their initial factory
defaults. Once the battery reaches Level 2 after falling to Level 5, reconfi gure the
current time, date, and other settings.
•
The watch’s Home City code setting will change automatically to
TYO
(Tokyo)
whenever the battery drops to Level 5. With this Home City code setting, the watch
is confi gured to receive the time calibration signals of Japan. If you are using the
watch in North America or Europe, or China you will need to change the Home City
code setting to match your location whenever the battery drops to Level 5.
•
Display indicators reappear as soon as the battery is charged from Level 5 to Level
2.
•
Leaving the watch exposed to direct sunlight or some other very strong light source
can cause the battery power indicator to show a reading temporarily that is higher
than the actual battery level. The correct battery level should be indicated after a
few minutes.
E-56
•
Performing illumination, or beeper operations during a
short period may cause
(recover) to appear on the
display.
After some time, battery power will recover and
(recover) will disappear, indicating that the above
functions are enabled again.
•
If
(recover) appears frequently, it probably means
that remaining battery power is low. Leave the watch in
bright light to allow it to charge.

Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Also note that allowing the watch to become very hot can cause its liquid crystal
display to black out. The appearance of the LCD should become normal again when
the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery 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
