If the display of the watch is blank...

l l lll ll ll

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.

Countdown Timer

Minutes Seconds

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 start of a surfing or a yacht race.

• All of the operations in this section are performed in the

Countdown Timer Mode, which you enter by pressing

C.

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 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.

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 beeps each second of the final 10 seconds before a countdown reaches zero, and at zero. 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.

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.

Battery power indicator

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. 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.

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 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 watch inside the sleeve of clothing can cause it to enter the sleep state.

• 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

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 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 indicates a falling tide. Neither nor is on the display at high tide and low tide.

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.

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 (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.

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.
