seconds.

• The stopwatch continues to run, restarting from zero

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.

Illumination

The watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch illuminates the display
automatically when you angle the watch towards your
face.

• The auto light switch must be turned on (indicated by

the auto light switch indicator) for it to operate.

• See “Illumination Precautions” for other important

information.

To turn on illumination manually

In any mode (except when a setting is on the display),
press B to illuminate the display.

• You can specify 1.5 seconds or 2.5 seconds as the

illumination duration. See “To set the time and date” for
more information.

• The above operation turns on illumination regardless of

the current auto light switch setting.

About the Auto Light Switch

Turning on the auto light switch causes illumination to turn on whenever you position
your wrist as described below in any mode. Note that this watch features a “Full Auto
EL Light,” so the auto light switch operates only when available light is below a certain
level. It does not illuminate the display under bright light.

Moving the watch to a position that is parallel to the ground and then tilting it
towards you at more than 40 degrees causes illumination to turn on.

• Wear the watch on the outside of your wrist.

40°

Warning!

Always make sure you are in a safe place whenever you are reading the watch

using the auto light switch. Be especially careful when running or engaged in
any other activity that can result in accident or injury. Also take care that
sudden illumination by the auto light switch does not startle or distract others
around you.

When you are wearing the watch, make sure that its auto light switch is turned

off before riding on a bicycle, or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.

To turn the auto light switch on and off

In any mode, hold down B for about two seconds to toggle the auto light switch on
(auto light switch indicator displayed) and off (auto light switch indicator not displayed).

• The auto light switch indicator remains in all modes while the auto light switch is

turned on.

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. Charging is reduced
significantly 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.

• 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 5 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 LOW indicator flashes on the display in the Timekeeping Mode when battery is

at Level 3.

• The LOW indicator at Level 3 and the flashing charge indicator (CHG) at Level 4 tell

you that battery power is very low, and that exposure to bright light for charging is
required as soon as possible.

• At Level 5, 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 4
(indicated by the flashing charge indicator) from Level 5. You will not be able to
configure any of the other settings until the battery reaches Level 3 (no charge
indicator) after dropping to Level 5.

• Leaving the watch in direct sunlight or some other very strong light source can cause the

battery power indicator to show a reading that is momentarily 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 (RECOV) appears and the following operations become disabled until
battery power recovers.

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

• Since these are the specs, we can include all the technical details.

• Display on 18 hours per day, sleep state 6 hours per day

• 1 illumination operation (1.5 seconds) per day

• 10 seconds of alarm operation per day

• Stable operation is promoted by frequent exposure to light.

Charging Guide

After a full charge, timekeeping remains enabled for up to about 13 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.
