LAP time
x Each press of B records the current lap time. Memory can hold up to 120lap
time records.
x Recording a lap time while there are 120records in memory will automatically
delete the oldest record to make room for the new one.
x The final lap time (time displayed when the elapsed time operation is stopped) is
recorded in memory when the stopwatch is reset to all zeros.
Memory
The watch has enough memory to hold up to 121records for session start
information (date and time), and lap time records. You can record up to 120lap
times.
x Session start information (date and time) requires one record for each session. A
session is from the start of measurement up the point the stopwatch is reset.
x Each lap time uses one record.
Example 1: Single session (from start to reset)
Start information (date and time) record + 120lap time records =
121records in total
Example 2: Multiple sessions
Session 1: Start information (date and time) record + 60lap time
records = 61records
Session 2: Start information (date and time) record + 59lap time
records = 60records
Total: 121records
