To turn auto repeat on and off
1. In the Countdown Alarm Mode, hold down
A until the hour digit of the countdown
time starts to flash, which indicates the
setting screen.
2. Press C three times to move the flashing
to the Auto Repeat setting.
3. Press D to turn auto repeat on (
ON
displayed) and off (OFF displayed).
4. Press A to exit the setting screen.
Note
• When the end of the countdown is reached while auto repeat is on, the
alarm sounds, but the countdown starts again automatically whenever
the countdown reaches zero. You can stop timing by pressing B, and
manually reset to the starting countdown time by pressing D.
• Normally, an alarm tone sounds for about 10 seconds when the end of
the countdown is reached. If you use auto repeat with start time of 10
seconds or less, the alarm tone sounds for only one second.
• Frequent use of auto repeat with a short countdown time can reduce
the charge of the rechargeable battery and cause the countdown time
alarm to become disabled, so it does not sound.

Backlight
The backlight uses an EL (electro-
luminescent) panel that causes the entire
display to glow for easy reading in the dark.
The watch’s auto light switch automatically
turns on the backlight when you angle the
watch towards your face.
• The auto light switch must be turned on
(indicated by the auto light switch on
indicator) for it to operate.
• See “Backlight Precautions” for other
important information about using the
backlight.
To turn on the backlight manually
In any mode, press L to illuminate the display for about two seconds.
• The above operation turns on the backlight regardless of the current
auto light switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight 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 turn on the
backlight under bright light.
• Be sure to wear the watch on the outside of your left wrist while using
the auto light switch.

Warning!
••
••
• Always make sure you are in a safe place whenever you are
reading the display of 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 surprise 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 the Timekeeping Mode, hold down D for two seconds to turn the auto
light switch on (
displayed) and off ( not displayed).
• The auto light switch on indicator (
) is on the display in all
modes while the auto light switch is turned on.
• Frequent use of the auto light switch greatly reduces the charge of the
rechargeable battery. If you use the auto light switch often, be sure to
leave the watch where it is exposed to sunlight during the daytime so it
can recharge the rechargeable battery. 10 minutes exposure to
sunlight provides enough of a charge for about 10 to 20 auto light
switch operations.
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.
Solar cell
• This watch employs a solar cell that converts light into electricity, which
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
ML-2016 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 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 battery power indicator on the display shows you the current status
of the rechargeable battery’s power.

• At Level 4, the display is disabled but timekeeping and other functions
continue to operate internally. Pressing any button causes the
Timekeeping Mode screen to appear for two or three minutes.
• At Level 5, 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 Data Bank 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.
• Frequent backlight and alarm operations over a short period put a
heavy load on the battery, which can cause the battery power indicator
to flash, indicating that the backlight and alarm are disabled. Normal
operations should return after the battery recovers from the overload
condition. The above condition can occur after about consecutive 200
backlight operations or about 360 alarm operations.
