Special Stage Timing
This section describes operations you can perform while
special stage timing is in progress.
To pause the current time on the display
While a special stage timing operation is in progress press
the D button.
• 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.

While a time is paused on the display (see above), press the B button.
• This will save the paused time in memory and display the ongoing special stage
timing operation.

oldest record to be deleted automatically to make room for the new one.
To reset the timing operation to zero
While a time is paused on the display (see above), hold down the B button.
• This will reset the elapsed time operation to zero.
To cancel an ongoing elapsed time measurement operation
Hold down the B button to reset the elapsed time operation to zero.
