• The first countdown timer of the series is the lowest numbered one with a start time
that is not zero. The final countdown timer of the series is the highest numbered
one with a start time that is not zero.
• While auto-repeat is turned off, the watch beeps when each countdown timer
reaches zero. An alarm will sound for about five seconds when the final countdown
timer reaches zero.
• While auto-repeat is turned on, the watch beeps once when each countdown timer
reaches zero. A five-second alert operation is performed when the final countdown
timer reaches zero, unless the start time of the final countdown timer is 10 seconds
or less. In such a case, the alert operation for the final countdown timer is only one
second long.
• Timing restarts from the first timer when the final countdown timer reaches zero.
The number of repeats is displayed in the lower display. The number of repeats
display changes to "- -" when the count reaches 100.
• An ongoing countdown timer operation continues to be performed even if you exit
the Countdown Timer Mode.
• To stop a countdown timer operation, first press D to pause the countdown of the
current timer, and then press A. This will display Countdown Timer 1 (INT 1).
