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: |
|
| 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. |

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
The
•The
•Even if you start a countdown operation from the reset time, the countdown automatically restarts from the countdown start time whenever it reaches zero.
•
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
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.
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.
