Getting Acquainted
Warning!
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.
If the display of the watch is blank...
About This Manual
If the P.SAVE indicator is flashing 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.
• See “Power Saving Function” for more information.

Always use proper instruments and resources to obtain data for navigation
purposes.
• This watch is not an instrument for calculating low tide and high tide times. The
tide graph of this watch is intended to provide a reasonable approximation of tidal
movements only.
• CASIO COMPUTER CO., LTD. assumes no responsibility for any loss, or any
claims by third parties that may arise through the use of this watch.

To set the time and date
Moon phase, tide graph data, and Moon/Tide Data Mode data will not be displayed
properly unless Home Site data (GMT differential, longitude, and lunitidal interval) is
configured correctly.
• The GMT differential is the time difference of the time zone where the site is located
and Greenwich Mean Time.
• The lunitidal interval is the time elapsing between the Moon’s transit over a meridian
and the next high tide at that meridian. See “Lunitidal Interval” for more information.
• This watch displays lunitidal intervals in terms of hours and minutes.
• The “Site Data List” and “Lunitidal Interval List” provide GMT differential, longitude,
and lunitidal interval information around the world.
• The following is the initial factory default Home Site data (Tokyo, Japan) when you
first purchase the watch, whenever battery power drops to Level 4, and whenever
you have the battery replaced. Change these settings to match the area where you
normally use the watch.

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.
Press A.

Year
Reset Time
You can set a “reset time,” which is a kind of alternate countdown start time you can
recall with the press of a button any time a countdown operation is in progress.
• When you enter the Moon/Tide Data Mode, the data that appears first is the Moon
data (Moon age and Moon phase indicator) for the current date as kept by the
Timekeeping Mode.
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.

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.

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.

• 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.
angle to the Moon in relation to the direction at which the Sun is visible from the
* 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 indicates a falling tide. Neither nor is on the display at
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.

USER’S GUIDE 2611
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.
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.
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.

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.
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
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.
