Countdown Timer
The countdown timer can be set within a range of one
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
Minutes Seconds
Configuring the Countdown Timer
The following are the settings you should configure before actually using the
countdown timer.
Countdown start time and reset time
Timer mode (auto-repeat, elapsed time)
Progress beeper on/off
• See “To configure the countdown timer” for information about setting up the timer.
Reset Time
You can specify any point between the countdown start time and the end of the
countdown as the “reset time”. Then while a countdown operation is in progress, you
can press a button to jump to the reset time and resume the countdown from there.
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.
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 emits a short beep each second of the final 10 seconds at the end of a
countdown, and a long beep 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.

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 at more than 40 degrees causes the backlight to turn on.
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
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 the Timekeeping Mode, hold down D for about two seconds to toggle the auto light
switch on (

light switch is turned on.
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 (except when a setting screen is on the
display), press B to illuminate the display for about one
second.
• The above operation turns on the backlight regardless of
the current auto light switch setting.

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. Even if the face of the watch
is only partially blocked from light,
charging will be significantly reduced.
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 fully charge, 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 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.
Battery Power Indicator
The battery power indicator on the display shows you the current status of the
rechargeable battery’s power.
Battery power indicator
• The flashing 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 and date, after the battery reaches Level 3
(indicated by flashing CHARGE indicator) from Level 4. You will not be able to set
any of the other settings until the battery reaches Level 2 (no CHARGE indicator)
after dropping to Level 4.
• Leaving the watch in direct sunlight or exposed to 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.
Backlight
Beeper tone
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
• The watch will not enter the sleep state between 6:00 AM and 10:59 PM. If the
watch is already in the sleep state when 6:00 AM arrives, however, it will remain in
the sleep state.
• The watch will not enter the sleep state while it is in the Countdown Timer Mode or
Stopwatch Mode.
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area.
• Press any button.
• Angle the watch towards your face for reading
To turn Power Saving on and off
Moon Phase Indicator
The Moon phase indicator of this watch indicates the current phase of the Moon as
shown below.
Moon Phase
Indicator
Moon Age
Moon Phase
• The Moon phase indicator shows the Moon as viewed at noon from a position in the
Northern Hemisphere looking south. Note that at times the image shown by the
Moon phase indicator may differ from that of the actual Moon in your area.
• The left-right orientation of the Moon phase is reversed when viewing from the
Southern Hemisphere or from a point near the equator.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle during which it appears to wax and
wane due to how the Sun illuminates the Moon and the relative positioning of the
Earth, Moon, and Sun. The greater the angular distance between the Moon and the
Sun,
the more we see illuminated.
*
The angle to the Moon in relation to the direction at which the Sun is visible from the
*
Earth.
The Moon age indicates the number of days from the New Moon to any particular
phase. It is normally calculated using either noon or midnight as a reference point.
This watch calculates the Moon age based on the angular distance of the Moon at
noon, which can result in an error of ± 1 day. Because of this, the appearance of the
Moon phase indicator may be different from that of the actual Moon.
The watch uses the following formula to calculate Moon age.
Moon Age (days) = 29.53 × (Moon angular distance / 360°)
Tide Graph
The wave on the watch’s tide graph indicates the current tide. indicates that the tide
is currently rising, while
high tide and low tide.
Tidal Movements
Tides are the periodic rise and fall of the water of oceans, seas, bays, and other
bodies of water caused mainly by the gravitational interactions between the Earth,
Moon and Sun. Tides rise and fall about every six hours. The tide graph of this watch
indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal
interval. The lunitidal interval differs according to your current location, so you must
specify a lunitidal interval in order to obtain the correct tide graph readings.
Lunitidal Interval
Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about
six hours later. Actual high tide occurs somewhat later, due to factors such as
viscosity, friction, and underwater topography. Both the time differential between the
Moon’s transit over the meridian until high tide and the time differential between the
Moon’s transit over the meridian until low tide are known as the “lunitidal interval.”
When setting the lunitidal interval for this watch, use the time differential between the
Moon’s transit over the meridian until high tide.
See the “Site/Lunitidal Interval Data List” for lunitidal interval information around the
world.
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.
• If you leave the watch in the Moon/Tide Data Mode and Alarm Mode for two or three
minutes without performing any operation, it automatically changes to the
Timekeeping Mode.
When turned on, the Power Saving function automatically
enters a sleep state whenever the watch is left in an area
where it is dark for 60 to 70 minutes. The sleep state is
indicated by a blank screen with P.SAVE 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.
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting screen.
2.Press C eight times until the Power Saving on/off
screen appears.
3.Press D to toggle Power Saving on (ON) and off (OF).
4.Press A twice to exit the setting screen.
• The Power Saving on indicator (P.SAVE) is on the
display in all modes while the Power Saving is turned
on.

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.
Initial Screens
When you enter the Timekeeping, World Time, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.
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.
World Time
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
• The GMT differential is the time difference between the time zone where the city is
located and Greenwich Mean Time.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
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 runs down the battery.
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 face and can run down the battery.
• 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 toward 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.
• Under certain conditions, the backlight may not light until about one second after you
turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
• 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.
