Important!
• Check to make sure that the speed hand is not moving before you perform any
Stopwatch Mode button operation.
Specifying a Distance Value
You can use the procedure below to specify a distance value, if you want. If you
specify a distance value, the watch will calculate and indicate speed for certain
stopwatch operations.
• The distance value represents kilometers, miles, or any other distance unit you want.
Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or 10.0
miles.
• No speed calculation is performed when 0.0 is specified as the current distance
value.
• For lap time readings, you can specify either the lap distance (when all the laps are
the same distance) or the total race distance.
• For split time readings, you can specify the total race distance only. Though the
watch will indicate a speed each time you take a split reading, they will be based on
the total race distance, and so they will not indicate actual intermediate split speeds.
