Configuring the Countdown Timer
The following are the settings you should configure before actually using the
countdown timer.
• Countdown start time and progress beeper start time settings
• Auto-repeat on/off
• Progress beeper on/off
Countdown start time
You can set a countdown start time from 1 to 60 minutes, in one-minute
increments.
Progress beeper start time
The progress beeper sounds every minute during the countdown, every 10
seconds during the final minute, and every second during the final five
seconds of the countdown. You can specify the start time of the progress
beeper, and turn progress beeper operation on or off. You can set the
progress beeper start time in 1-minute increments to any value that is not
greater than the countdown start time.
Auto-repeat on/off
Auto-repeat automatically restarts the countdown from the countdown start
time you set whenever zero is reached. Turning off auto-repeat causes the
countdown to stop and the countdown start time to appear on the display
when the end of the countdown is reached.

Countdown Timer
The countdown timer can be set within a range of
1 to 60 minutes. An alarm sounds when the
countdown reaches zero. An auto-repeat feature
causes the countdown to restart automatically
when the end of a countdown is reached, and a

countdown. All of this makes the countdown timer
a valuable tool for timing the start of a yacht race.
