Stopwatch
The Stopwatch Mode lets you time a game or event. The
upper display shows non-stop total elapsed time, while
the lower display shows event elapsed time, which can be
paused as required for time outs, half time, etc.
• The measurement limit of the upper display (total time)
is 99 minutes 59 seconds.
• The measurement limit of the lower display (event time)
is 59 minutes 59 seconds.
• A stopwatch measurement operation continues to run
until you stop it. If either time reaches its measurement
limit, it will restart from zero.
• A stopwatch measurement operation continues even if
you exit the Stopwatch Mode.
• Starting event timing will cause the display to change to
the Elapsed Time Screen from the initial screen shown
on this page.
• All of the operations in this section are performed in the Stopwatch Mode, which you
enter by pressing B.

Using the Stopwatch Mode to Time a Sporting Event
You can time a sporting event with the Stopwatch Mode either with or without
presetting the duration of the event. If you do, the watch will beep when the total time
in the upper display reaches the preset event duration.
If the event is interrupted for timeouts or some other reason, press D to pause and
restart event time measurement in the lower display. Since total time measurement
continues in the upper display, you can calculate the time that play was interrupted
(lost time) by subtracting the time in the lower display from the time in the upper
display.
