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.

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 normally
exposed to light whenever possible.

·

This watch employs a solar cell that converts light into electricity that charges
a built-in rechargeable battery. 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 the rechargeable battery
replaced.

·

The rechargeable battery should be replaced with a CASIO-specified CTL1616
battery only. Other rechargeable batteries can cause damage to the watch.

Battery Power Indicator
The battery power indicator on the display shows you the current status of the
rechargeable battery’s power.

·

Turn on the watch’s sleep mode and keep it in an area normally exposed to
light when storing it for long periods. This helps to keep the rechargeable
battery from going dead.

·

At Level 4, all functions are disabled. Functions are enabled once again after the
rechargeable battery is charged, but anything previously stored in memory is lost.
Because of this, you must set the current time and alarms, and re-input
Telememo records after the rechargeable battery is charged.

·

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
actually higher than the 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, a
RECOVER indicator (        )appears on the display and the following
operations become disabled until battery power recovers.
Backlight
Alarm and hourly time signal
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.

Warning!
Leaving the watch in sunlight to charge its rechargeable battery can
cause it to become quite hot. Take care when handling the watch to avoid
burn injury.

·

On the dashboard of a car parked in direct sunlight

·

Too close to an incandescent lamp

·

Under direct sunlight or in any other area exposed to intense heat for long
periods
