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 Auto-repeat mode automatically restarts the countdown from the countdown start time you set whenever zero is reached. � 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 to 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. 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 fours short beeps at the top of each minute during the reset period, and 30 seconds before the end of the countdown.
