About This Manual
� Button operations are indicated using the letters shown in the illustration. � Each section of this manual provides you with the information you need to perform operations in each mode. Further details and technical information can be found in the �Reference� section.

If the display of the watch is blank...
If the SLEEP indicator is 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. * It can take up to five seconds for the display to turn on. � See �Power Saving Function� for more information.

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 first five beeps (seconds 10 through 6) are higher pitched than the final five beeps (seconds 5 through 1). 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.

4. Press A to exit the setting screen. � See �Power Saving Function� for details about configuring Power Saving settings. � The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all modes. � The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.

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 yacht race. � All of the operations in this section are performed in the

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.
