Your data won’t be lost. Indeed, Optima is recording the data systematically since they come from GPS or from the instruments. The tape is only used to specify, when recording, that data are useful for a polar calculation.
If you have forgotten to tick the tape, you can correct the recordings:
- go to menu “Tracks -> correct recordings” (Adrena) or “Tools -> correct recordings” (Optima).
- select the timetable to correct.
- pick “Force ‘under sail’ mode”
- click on “Run”
If you have forgotten to tick the tape after the navigation, you can use the same procedure by specifying “Force ‘engine powered’ mode”.
