to start.
Creates a new log. Stores the date the button was
pressed, and the new log number.
Press
A
to display lap/split time.
Creates a new record with each button operation. Stores
the lap and split times and total elapsed time at each
point the button is pressed.
Press
D
to stop elapsed time
measurrement and then press
A

Memory Management
A new log is created each time you press
D
in the Stopwatch Mode to start a new
elapsed time measurement operation. A log contains a log title screen, and records of
all the lap or split times you record during the current elapsed time measurement
operation.
• The capacity of the watch’s memory is 60 records.
• If you are adding records to the only log in memory and watch memory becomes
full, adding another record causes the oldest record in the log to be deleted
automatically to make room for the new record.
• If you are adding records to a log when there are multiple logs in memory and
watch memory becomes full, adding another record causes the oldest log in
memory and all of its records to be deleted automatically to make room for new
records.
