To turn the auto light switch on and off
In any mode, hold down L for about two seconds to toggle the auto light switch on
(the auto light switch indicator displayed) and off (the auto light switch indicator not
displayed).
• The auto light switch indicator is on the display in all modes while the auto light
switch is turned on.
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.
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 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
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.

• The flashing charge 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 4, all functions are disabled and settings return to their initial factory
defaults. Functions are enabled once again after the rechargeable battery is
charged, but you need to set the time and date, after the battery reaches Level 3
(indicated by the flashing charge indicator (
)) from Level 4. You will not be able
to configure any of the other settings until the battery reaches Level 2 (no charge
indicator) after dropping to Level 4.
• The Home City reverts to TYO (Tokyo), which means that the watch is configured
to receive the Japanese time calibration signal, whenever battery power drops to
Level 4. If you are using the watch in North America, you will need to configure your
Home City code setting whenever battery power recovers after dropping to Level 4.
• Leaving the watch in direct sunlight or some other very strong light source can cause the
battery power indicator to temporarily show a reading that is higher than the actual
battery level. The correct battery power indicator should appear after a few minutes.
• If you use the light or alarms a number of times during a short period, the recover
indicator appears on the display and the following operations become disabled until
battery power recovers.
Illumination
Beeper tone
Coordination between digital and analog timekeeping
Time calibration signal reception
After some time, battery power will recover and the recover indicator will disappear,
indicating that the above functions are enabled again.
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
After a full charge, timekeeping remains enabled for up to about 7 months.
• 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.
