Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully and keep it on hand for later reference when necessary.

Keep the watch exposed to bright light

							• 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 reduced
							significantly.

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will cause some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

•The actual level at which some functions are disabled depends on the watch model.

•Frequent display illumination can run down the battery quickly and require charging. The following guidelines give an idea of the charging time required to recover from a single illumination operation.

Approximately 5 minutes exposure to bright sunlight coming in through a window Approximately 50 minutes exposure to indoor fluorescent lighting

•Be sure to read “Power Supply” for important information you need to know when exposing the watch to bright light.

If the display of the watch is blank...

If the display of the watch is blank, it means that the watch’s Power Saving function has turned off the display to conserve power.

• See “Power Saving Function” for more information.

Warning!

•The longitude, lunitidal interval, Moon phase indicator and tide graph data that appear on the display of this watch are not intended for navigation purposes. 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.

Home Site Data

Moon phase, tide graph data, and Moon/Tide Data Mode data will not be displayed properly unless the Timekeeping Mode current date and time settings and 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/Lunitidal Interval Data 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.

GMT differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours, 20 minutes)

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
		start of a surfing or a yacht race.
Minutes	Seconds	• 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 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.
