Calibration to factory settings
With this calibration method
altitude is calculated using the
difference between the currently
measured pressure and normal
pressure at sea level. Keep
pressing the “PILOT” key until
the altitude indicator “ALTI” ap-
pears. Press the “MODE” key for
2 seconds. The fl ashing “SET”
symbol and “ZERO” are display-
The air pressure at sea level is

1013.2 mb.
Because the pressure at sea le-
vel constantly changes, however,
the indicated altitude is inexact
and only offers approximate
orientation.
