To specify a reference altitude
1. In the Altimeter Mode, hold down A for about
two seconds until either OFF or the current
reference altitude value starts to flash. This is
the setting screen.
2. Press E (+) or B (–) to change the current
reference altitude value by 5 meters.
• You can specify the reference altitude within
the range of –10,000 to 10,000 meters.
• To clear the reference altitude value (and return it to OFF so the watch
performs air pressure to altitude conversions based on preset data only),
press E and B at the same time.
3. Press A to exit the setting screen.
