Test of NautoPilot Operator Unit

Note:
This test is not used to test the Autopilot control functions.
This test serves for testing the function of the display, the LEDs, the rotary knob and the
buttons.
This test should be activated from time to time or in the case of an assumed malfunction
of an operation feature such as the display, the LEDs, the rotary knob or a button.
The test can only be started in a non automatic mode, i.e. "Manual", "Standby" or "Over-
ride" only.
Start the test by pressing the "SET" and "Illumination" buttons simultaneously for
approx. 5 seconds.
The display lights up in red, green, blue and black for approx. 15 seconds. Parallel to
this the LEDs for Heading, Course and Track light up green and yellow and the LED for
alarm and "SET" request light up yellow.
During this test it is possible to check that the LEDs are lit and that the display shows no
blank/dark dots.
The following tests request several different operator actions to test the function of the
rotary knob, the buttons at the frontplate and some softkey functions on the display.
Each single test task is displayed as a request to the operator.
Operator actions must be performed within a set time window -- this is shown with a
countdown bar.
The test is finished:
-- Pressing the "SET" button at any time or
-- double click (double touch) on the touch screen at any time or
-- or if the time window exceeds its limit.
The test is aborted/finished and the previous display is shown again.
If defect dots on the Autopilot display result in lack of or wrong information, the replace-
ment of the NautoPilot Operator Unit is recommended.
Single dot failures do not legitimate for warranty claims.
