Important!
•Pressing D again after stopping dive time measurement will cause timing to resume from where it was stopped.
•Dive time/interval measurement continues internally if you exit the Diving Mode without resetting. A diving log record is not created in this case.
Diving Log Records
A new diving log record is created whenever you reset a dive time measurement, either by pressing A to start interval measurement or by holding down C to exit the Diving Mode.
•Each diving log record includes a log number, the dive time, the dive start date and time, and the interval prior to the dive (if there was one).
•There is enough memory for 10 diving log records. If there are already 10 diving log records in memory when you perform a reset operation, the oldest record currently in memory is deleted automatically to make room for the new record.
To view diving log records
1.In the Timekeeping Mode, press C to enter the Diving Log Recall Mode.
•This displays the newest record in memory.
•The interval currently being measured is displayed on the screen of the newest diving log record.
•
•If you do not perform any operation for about one or two hours in the Diving Log Recall Mode, the watch will automatically return to the Timekeeping Mode.
2.Press D to scroll through the log records, from newer to older.
•Log numbers are lower for older log records.
