4.2.6.4 Verifying correct joystick calibration
To verify the correct calibration of the joystick, see the last line on the page where there are three parameters
(X, Y, Z) followed by a number that changes according to the position reached by the joystick.
The table shows the values for the positions taken by the joystick.
Position of joystick X Y Z
Joystick released 7 7 7
Joystick to far right 14 7 7
Joystick to far left 0 7 7
Joystick completely up 7 14 7
Joystick completely down 7 0 7
Zoom to far left 7 7 14
Zoom to far right 7 7 0
At intermediate positions, the variables X, Y and Z will take on intermediate values between the departure and
arrival positions.
4.2.6.5 Calibrating the touch screen
WARNING
Only carry out this procedure if the display has been replaced or if there are obvious faults in its
behaviour when the keys are pressed..
To verify correct touch screen operation use the “Touch Test” procedure (see § 4.2.6.6 - Touch
test, page 43).
Calibrating the touch screen can be carried out to compensate for possible shifts in the sensitive surface of the
display with ageing or if it has to be replaced.
The system can be recalibrated by inserting the coordinates of the two corners of the display.
WARNING
During this procedure the system enters a particular mode in which the touch screen is slowed
down when reading, and recognition of the three central manoeuvre keys may prove to be more
difficult.
