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 efficiency 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 significantly if the face is
covered only partially.

E-41
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.
•
All data stored in memory is deleted, and the current time and all other settings
return to their initial factory defaults whenever battery power drops to Level 5 (pages
E-42 and E-43) and when you have the battery replaced.
•
Turn on the watch’s Power Saving function (page E-56) 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.

The flashing
LOW
indicator at Level 3 tells 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, reconfigure 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.
•
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.

•
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

Charging Guide
The following table shows the amount of time the watch needs to be exposed to light
each day in order to generate enough power for normal daily operations.
•
For details about the battery operating time and daily operating conditions, see the
“Power Supply” section of the Specifications (page E-63).
•
Stable operation is promoted by frequent exposure to light.

functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the
current phase of the Moon as shown below. It is based on
the view of the left side of the moon at meridian transit
from the northern hemisphere of the Earth. If the
appearance of the Moon phase indicator is reversed from
the actual Moon as viewed from your location, you can
use the procedure under “To reverse the displayed Moon
phase” (page E-22) to change the indicator.
