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.

• Note that charging efficiency drops

when any part of the solar cell is

blocked by clothing, etc.

• The illustration shows how to position

a watch with a resin band.

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 bright 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.

• 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 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

The battery power indicator on the display shows you the current status of the

rechargeable battery's power.

disabled.

All functions, including

timekeeping, are disabled.

• The Level 3 charge warning indicator 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 current time, date, and all other settings after the

battery is recharged to Level 2 from Level 4. Though the time appears on the display

after the battery is charged to Level 3, you will not be able to change the time setting

until the battery reaches Level 2.

• 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 backlight or the 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.

Calibration 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 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, all functions of the watch remain enabled for up to about six

months, the watch is used under the conditions described below.

Operating Conditions

• Watch is not exposed to light

• 1 backlight operation (1.5 seconds) per day

• 10 seconds of alarm operation per day

• 3 times calibration reception per day

Charge Times

Exposing the watch to light for the periods shown below each day restores the power

used by the above operating conditions.
