8. Press the SOUTH button; you will see the message, COLLECTING DATA FOR
SOUTH along with a 15 second timer. Let the time run out before proceeding.
9. Align the aircraft pointing magnetic West as closely as possible.
10. Press the WEST button; you will see the message, COLLECTING DATA FOR WEST
along with a 15 second timer. Let the time run out before proceeding.
11. Press the END button. This will cause the EFIS-D10A to pause as it calculates. This
pause should last between 1-20 seconds. However, if the collected data is poor, this can
take as long as 5 minutes. A message will be displayed onscreen: CALCULATING
MAGNETIC CALIBRATION VALUES.
12. Wait for the message CALIBRATION COMPLETE before attempting to use the EFIS-
D10A or remove power. Press BACK to leave the menu.
This completes the EDC-D10A calibration process. The process can be repeated as often as
desired. The overall accuracy of the compass depends on the installation location (away from
any ferrous materials or current carrying wires or devices), the installation alignment (aligned
with the EFIS-D10A in pitch, roll, and yaw), and the calibration procedure (accurately aligning
the aircraft with North, East, West, and South and having the correct magnetic inclination angle
loaded into the EFIS-D10A). If the compass performance is not adequate for your usage, we
suggest that you investigate each of these factors and try to optimize your installation for each
factor.
If the heading shown onscreen is off by a small, but constant amount, you can change a heading
offset in the EFIS-D10A which will correct this. Orient your plane in a known direction,
preferably on a compass rose at the airport. Navigate to the Heading Adjustment menu by
pressing MORE > SETUP > MORE > MORE > MAGADJ. Increment or decrement the value of
the heading offset until the EFIS-D10A heading corresponds to the direction in which your plane
is pointed.
Troubleshooting
During the calibration process you may receive one of the following errors. Next to each one is
the corrective action required.

ERR: NOT ENOUGH DATA FOR XXXXXX
TURN
One of the 3 maneuvers did not take enough
time for the EFIS-D10A to collect enough
data. Please perform just the listed maneuver
again, ensuring that you take at least 2 minutes
to perform the turn.
