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. Even if the face of the watch
is blocked from light only partially,
charging will be reduced significantly.
Solar cell
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. Make 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.
• The current time and all other settings return to their initial factory defaults whenever
battery power drops to Level 3 and when you have the battery replaced.
• Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to keep the rechargeable battery from going dead.
Battery Power Levels
The movement of the analog hands indicates the current battery power level.
• The second hand jumping every two seconds (Level 2) indicates that battery power
is quite low. Expose the watch to light as soon as possible to charge the battery.
• When battery power is at Level 2, time calibration signal reception is disabled.
Hand Movement
Normal.
•Second hand jumps
every 2 seconds.
•Date changes to home
position.
•Second hand stopped.
•Hour and minute hands
stopped at 12 o’clock.

• At Level 3, all functions are disabled and settings return to their initial factory
defaults. The analog hands will move to the current time and normal timekeeping will
resume when the battery is recharged sufficiently.
• Alarm operation can cause hand movement to stop due to the sudden temporary
drop in battery power. This does not indicate malfunction, and normal operation will
resume when the watch is exposed to light. Though hand movement stops,
timekeeping continues internally, and the hands will be adjusted to the correct
setting when normal operation returns.
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.
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
