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.

If the digital display of the watch is blank...

If the SLEEP indicator is on the display (either flashing or steady), 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 the 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 the watch towards your face for reading.

It can take up to two seconds for the display to turn

on.

• See “Power Saving Function” for more information.

Setting the Time and Date

When setting the time, you can also configure settings for the display illumination duration, the 12/24-hour format, power saving on/off, and the Dual Time screen.

About the Dual Time screen

The Dual Time screen is initially set up to show the time in Kona, Hawaii, which is the site of the Ironman Triathlon. You can leave this setting the way it is or change it to show the current time in another time zone.

• If you need to adjust the current Kona time setting, use the “Time Differential Table” for reference. If you live in Tokyo for example, you would need to subtract 19 hours from the current Tokyo time to determine the current time in Kona, Hawaii. Note that the times in the “Time Differential Table” are standard times. You need to subtract one hour from these times during periods when summer time (Daylight Saving Time) applies.

• You can also use the Dual Time screen to keep track of the current time in another area outside of the Kona, Hawaii time zone. If you do, you should turn off (Kona time zone indicator) on the Dual Time screen. This will cause the indicator to be replaced by an indicator that shows the day of the week for the current date.

Stopwatch

The 1/100-second stopwatch measures elapsed time, as well as lap/split times. The Stopwatch Mode also includes a number of features and functions for the triathlete, including lap/split time memory, auto-start, target splits, leg (event) indicators, and more.

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

Stopwatch Mode, which you enter by pressing D.

• See “Timing a Triathlon” for information about triathlon functions.

Measuring Elapsed Time

Use the following procedure to perform a basic elapsed time operation with the stopwatch.

• The stopwatch continues to run until you stop it. If the elapsed time measurement reaches the maximum limit, it will restart from zero.

1. In the Stopwatch Mode, press A to start the elapsed

time measurement.

• Starting an elapsed time operation displays the elapsed time in the center of the display and in the lower part of the display.

• Note that pressing A will not start an elapsed time operation while an auto-start countdown is being performed. In this case, you need to stop the autostart countdown before starting the elapsed time operation.

• Elapsed time measurement continues even if you exit the Stopwatch Mode.

2. To stop elapsed time measurement, hold down C for

about two seconds until the watch emits two short beeps and then one long beep.

3. To clear the displayed stopwatch times to all zeroes, stop elapsed time

measurement and then hold down C for two seconds until the display and the watch beeps.

• Keep C depressed until the watch beeps. If you release C after

flash but the watch does not beep yet, the Stopwatch Mode measured times will reappear.

Recording Lap and Split Times

“Lap time” is the time spent to cover a specific segment of a race, such as one lap around a track. “Split time” is the time spent from the beginning of a race up to a certain point.

• The explanations in this section describe general lap and split time registration, without using the target split feature for triathlon timing. They assume that all target splits are turned off. See “Timing a Triathlon” for more information about target splits.

• Lap/split times are stored in memory automatically whenever you perform a lap/split time operation with the C button. See “Recall Mode” for more information.

To record lap/split times

4. To stop the elapsed time measurement, hold down C for about two seconds, until

the watch emits two short beeps, followed by one long beep.

• After stopping elapsed time measurement, you can resume it by pressing A.

5. To clear the displayed stopwatch times to all zeroes, stop elapsed time

measurement and then hold down C for two seconds until the display and the watch beeps.

• Keep C depressed until the watch beeps. If you release C after flash but the watch does not beep yet, the Stopwatch Mode measured times will reappear.

Auto-start

Auto-start automatically starts a stopwatch elapsed time operation when a time set by you is reached.

• Auto-start is coordinated with the current Timekeeping Mode time. The stopwatch elapsed time operation will start automatically when the auto-start time you specify is reached in the Timekeeping Mode.

• Note that you can configure an auto-start time or turn auto-start on or off only while the Stopwatch Mode screen shows all zeroes.

4. Press B to exit the setting screen.

While the Stopwatch Mode screen shows all zeroes, hold down E for about one second to toggle auto-start on (countdown displayed) and off (all zeroes displayed).

• When auto-start is turned on, the Stopwatch Mode screen counts down the time remaining until the autostart time is reached. When the countdown reaches zero, the watch beeps three times and a stopwatch elapsed time operation starts automatically, regardless of the mode the watch is currently in.

• The auto-start countdown continues, even if you exit the Stopwatch Mode.

• Note that a stopwatch elapsed time operation cannot be started manually by pressing A while an auto-start countdown is in progress. You need to turn off auto-start before using the stopwatch.

Timing a Triathlon

You can configure the watch with up to five target split

times and leg indicators. Then when you time the legs of a

number

triathlon, the watch will display the leg indicators during each leg, and beep when a preset target split time is reached. You can even display the difference between a preset target split time and your actual split.

• See “Stopwatch” for full details about using the Stopwatch Mode and for more information about lap and split time operations.

Configuring the Watch for Triathlon Timing

You can use the Target Mode to configure the watch with target splits, and to display leg indicators during timing of each leg. Configuring the watch for timing a triathlon consists of the following three steps.

1 Setting target split times 2 Specifying leg indicators 3 Turning on the target splits you want to use

Target Splits and Leg Indicators

You can configure the watch up to five target lap/split times ( specify leg indicators (Swim, Bike, Run) that appear on the display on the Stopwatch Mode screen during timing of each leg. The following shows examples of two possible configurations that you can use.
