Measured elapsed time

While a special stage timing operation is in progress press the Dbutton.

•This will pause the current elapsed time (flashing) on the display for about one or two minutes. Though the time is frozen on the display, the watch continues the special stage timing operation (and count down of the remaining target time) internally.

•While a time is paused on the display, you can record it in memory or reset the timing operation to zero. If you don’t do anything, the display will return to the normal elapsed time measurement screen after a few minutes.
