Battery
This watch is equipped with a solar cell and a 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.
• Normally, you should try to keep the
watch outside of your sleeve as much
as possible. Charging is significantly
reduced if the face is only partially
covered.
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 normally exposed to bright light
whenever possible.
• Normally, the rechargeable battery should not need replacement, but after very long
use over a number of years, the rechargeable battery may lose its ability to achieve
a full charge. Should you notice problems with getting the rechargeable battery to a
full charge, contact your dealer or CASIO distributor about having it replaced.
• The rechargeable battery should be replaced with a CASIO-specified CTL1616
battery only. Other rechargeable batteries can cause damage to the watch.
• All data stored in memory is deleted, and the current time and all other settings
End mark
return to their initial factory defaults whenever battery power drops to Level 4 and
when you have the battery replaced.
• Turn on the watch's Power Saving function 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.
Battery Power Indicator and Recover Indicator
The battery power indicator on the display shows you the current status of the
rechargeable battery's power.

after it reaches its limit, until you stop it.
• Exiting the Stopwatch Mode while a split time is frozen
on the display clears the split time and returns to
elapsed time measurement.
• The stopwatch measurement operation continues even if
you exit the Stopwatch Mode.
• All of the operations in this section are performed in the
Stopwatch Mode, which you enter by pressing C.
