FusedAlti

FusedAltiTM provides an altitude reading that is a combination of GPS and barometric altitude. It minimizes the effect of temporary and offset errors in the final altitude reading.

NOTE:

By default, altitude is measured with FusedAlti during exercises that use GPS and during navigation. When GPS is switched off, altitude is measured with the barometric sensor.

If you do not want to use FusedAlti in altitude measurement, you can disable it in the options menu.

To disable FusedAlti:

Keep Next pressed to access the options menu.
Scroll to Alti-baro with Light Lock and enter with Next.
Scroll to FusedAlti with Start Stop and select with Next.
Set FusedAlti Off with Start Stop or Light Lock and accept with Next.
