Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to carefully read this manual and keep it on hand for later reference
when necessary.
Expose the watch to bright light to charge its battery before using it.
You can use this watch even as its battery is being charged by exposure to bright
light.
• Be sure to read “Battery” of this manual for important information you need to
know when exposing the watch to bright light.
About This Manual
(Light)
If the display of the watch is blank...
If the SLEEP indicator is on the display, it means that the
display is blank because the watch’s Power Saving
function has turned off the display to conserve power.
Power Saving automatically turns off the display and
enters a sleep state whenever your watch is left for a
certain period where it is dark.
• The initial factory default setting is Power Saving on.
• The watch recovers from the sleep state if you move it to
a well-lit area*, if you press any button, or if you angle
the watch towards your face for reading.
It can take up to five seconds for the display to turn on.
*
• See “Power Saving Function” for more information.
• Depending on the model of your watch, display text
appears either as dark figures on a light background, or
light figures on a dark background. All sample displays
in this manual are shown using dark figures on a light
background.
• Button operations are indicated using the letters shown
in the illustration.
• Each section of this manual provides you with the
information you need to perform operations in each
mode. Further details and technical information can be
found in the “Reference” section.

Timer Mode
The countdown timer gives you a choice of two modes: auto-repeat and elapsed time.
Auto-repeat
The auto-repeat mode automatically restarts the countdown from the countdown start
time you set whenever zero is reached.
• The auto-repeat mode is best when timing the starts of match races.
• Even if you start a countdown operation from the reset time, the countdown
automatically restarts from the countdown start time whenever it reaches zero.
• Auto-repeat timing repeats up to seven times.
Elapsed Time
When the end of the countdown is reached in the elapsed time mode, the timer
automatically switches to an elapsed time measurement operation.
• The elapsed time mode is best when timing the speed of yachts during ocean races.
• The elapsed time operation is performed in one-second increments up to 99 hours,
59 minutes, 59 seconds.

minute to 60 minutes. An alarm sounds when the
countdown reaches zero. The countdown timer has two
modes: auto-repeat and elapsed time, and a progress
beeper signals the progress of the countdown. All of this
makes the countdown timer a valuable tool for timing the
start of a yacht race.
• All of the operations in this section are performed in the
Countdown Timer Mode, which you enter by pressing
C.
Countdown Timer Beeper Operations
The watch beeps at various times during a countdown so you can keep informed
about the countdown status without looking at the display. The following describes the
types of beeper operations the watch performs during a countdown.
Countdown End Beeper
The watch beeps each second of the final 10 seconds before a countdown reaches
zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than
the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal
when the countdown reaches zero.
• The countdown end beeper always sounds, regardless of the on/off status of the
progress beeper.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and a reset
period progress beeper.
• The reset time beeper and reset period progress beeper sound only while the
progress beeper is turned on.
Reset Time Beeper
The reset time beeper is similar to the countdown end beeper. When the progress
beeper is turned on, the watch beeps each second of the final 10 seconds before the
countdown reaches the reset time.
Reset Period Progress Beeper
The reset period is the portion of the countdown between the reset time and zero.
When the progress beeper is turned on, the watch emits four short beeps at the top of
each minute during the reset period, and 30 seconds before the end of the
countdown.
Configuring the Countdown Timer
The following are the settings you should configure before actually using the
countdown timer.

Backlight
Auto light switch
on indicator
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
one second.
• 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 for about one second,
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.
Moving the watch to a position that is parallel to the ground and then tilting it towards
you more than 40 degrees causes the backlight to turn on.
• Wear the watch on the outside of your wrist.
Parallel to
ground
More than
40°
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 about two seconds to toggle the auto light
switch on (auto light switch on indicator displayed) and off (auto light switch on
indicator not displayed).

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, 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 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.

Beeper tone, backlight,
display, and buttons are
disabled.
All functions, including
timekeeping, are disabled.
• The flashing L-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, 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 higher than
the actual battery level. The correct battery power indicator should appear after a
few minutes.
• If you use the backlight or any of the alarm functions a number of times during a
short period, RECOVER appears on the display and the following operations
become disabled until battery power recovers.

After some time, battery power will recover and RECOVER 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

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Power Saving Function
When turned on, the Power Saving function automatically
puts the watch into a sleep state whenever it is left in an
area where it is dark for 30 to 35 minutes. The sleep state
is indicated by a blank screen with SLEEP flashing on it.
In the sleep state, all functions are enabled, except for the
display.
• Wearing the watch inside the sleeve of clothing can
cause it to enter the sleep state.
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area. It can take up to five seconds for the display to turn
on.
• Press any button.
• Angle the watch towards your face for reading.
||||
||||
To turn Power Saving on and off

||||||
Auto Return Feature
If you leave a screen with flashing digits on the display for two or three minutes without
performing any operation, the watch automatically saves any settings you have made
up to that point and exits the setting screen.
Data and Setting Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The year can be set in the range of 2000 to 2039.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except when battery power drops to Level 4.
Backlight Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery operating time.
Auto light switch precautions
• Wearing the watch on the inside of your wrist, as well as movement or vibration of
your arm can cause the auto light switch to activate and illuminate the display. To
avoid running down the battery, turn off the auto light switch whenever engaging in
activities that might cause frequent illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is turned
on can cause frequent illumination of the display and can run down the battery.
More than 15 degrees
too high
• The backlight may not light if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
• The backlight turns off in about one second, even if you
keep the watch pointed towards your face.
• Static electricity or magnetic force can interfere with
proper operation of the auto light switch. If the backlight
does not light, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back
towards you again. If this does not work, drop your arm
all the way down so it hangs at your side, and then bring
it back up again.
