Problem Solution
After performing a magnetic calibration the EFIS-
D10’s heading is wrong by a constant amount. Orient your plane in a known direction, preferably on a compass
rose at the airport. Navigate to the Heading Adjustment menu by
pressing SETUP -> MORE -> MAGADJ. Increment or decrement
the value of the heading until the EFIS-D10 heading corresponds to
the direction in which your plane is pointed.
When the barometer on the unit is set correctly,
the displayed altitude is wrong by a constant
amount. Set the barometer to the correct value for your current location and
altitude. Note the difference between the displayed altitude and the
actual altitude for your location. Navigate to the Altitude
Adjustment menu by pressing SETUP -> MORE -> ALTADJ.
Increment or decrement the value of the altitude until the EFIS-D10
altitude corresponds to that of the current location of your plane.
See diagram below for more information.
