YACHT TIMER MODE
u
Yacht timer combines the functions of a count down timer and a stop watch
that starts operating automatically when the timer finishes counting down.
This function is particularly useful in yacht racing.
l
Yacht timer operation
• There are pre-set yachting timer modes: -minute, 6-minute and
10-minute timers.
• Upon activating the yacht timer function, the selected yacht timer starts
counting down in 1-second increments.
• The remaining time is indicated by the center hand and the two hands
of the small watch, which turn counterclockwise while the yacht timer is
counting down.
• When the yacht timer finishes counting down, the beep will sound
indicating that time is up and the measurement is automatically switched
to the stopwatch.
• The stopwatch can measure 12 hours in 1-second increments. When the
measurement reaches 12 hours, the stopwatch automatically stops.
