E-44
To take a manual altitude reading
1. Press C to enter the Altimeter Mode (page E-11).
2. Hold down C for about one second until the watch beeps and REC
flashes on the display.
• This indicates that the current altitude reading, current date (year,
month, day), and time are being saved to memory.
3. REC will stop flashing and the watch will return to the Altimeter Mode
automatically after data save is complete.
• Memory can hold up to 20 altitude records. Storing a new reading while
there already are 20 in memory will delete the oldest record to make room
for the new reading.
To take altitude readings using the Altimeter Mode stopwatch
1. In the Timekeeping Mode, use the C button to enter the Altimeter Mode.
• The watch will start altitude measurement automatically. Note that these
readings are not saved as altitude records (page E-45).
