Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to read this manual carefully.
Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is
stored by a built-in battery. Leaving or using the watch
where it is not exposed to light causes the battery to run
down. Make sure the watch is exposed to light as much as
possible.
•When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
•You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced significantly if
the face is even only partially covered.

Power Supply
This watch is equipped with a solar cell and a special rechargeable battery (secondary
battery) that is charged by the electrical power produced by the solar cell. 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 cell 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 even only
partially covered.
Solar cell
E-39
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 special rechargeable battery to store power produced by the solar
cell, 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 special rechargeable battery to charge fully, contact your dealer
or CASIO distributor about having it replaced.
•Never try to remove or replace the watch’s special 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 (CHG)
(page E-40) and when you have the battery replaced.
•Turn on the watch’s Power Saving function (page E-48) 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 (L) 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 (CHG), all functions are disabled and settings return to their initial factory
defaults. Once the battery reaches Level 2 (M) after falling to Level 5 (CHG),
reconfigure the current time, date, and other settings.
•Display indicators reappear as soon as the battery is charged from Level 5 (CHG) to
Level 2 (M).
•The watch’s Home City code setting will change automatically to TYO (Tokyo)
whenever the battery drops to Level 5 (CHG). If this happens, change the Home City
to the setting you want (page E-11).
•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-42
•Overuse of display illumination or the beeper can cause
the R(Recover) indicator to appear in the upper display,
which indicates that the watch is in the battery power
recovery mode. Face illumination, the alarm, the
countdown timer alarm, and all hand operations are
disabled in the power recovery mode. The watch
continues to keep time internally, so normal timekeeping
and function will resume as soon as battery power
recovers to normal levels, which is indicated when the R
indicator disappears.
•If Rappears frequently, it probably means that
remaining battery power is low. Leave the watch in bright
light for some time 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
