functions of this watch.
Stopwatch Modes
The following describes how to perform data storage and measurement in the
stopwatch modes.
Managing Memory Data
Pressing the D button in the Single Stopwatch Mode or the D or B button in the
Dual Stopwatch Mode to start a new elapsed time measurement operation creates a
new log in memory.
A new log is created each time you start a new elapsed time measurement operation.
A log contains a log title screen, and records of all the lap times that are recorded
during elapsed time measurement.
• The capacity of the watch's memory is 50 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.
