action is performed. A green light will light.
If necessary, check Invert check box, to reverse the operation of digital input.
Once digital inputs are connected the system will warn pilot, if airbrakes are open on take-

Instead of using magnetic switch on flaps to toggle between SC (cruise) and
climb mode you can also use flap sensor for this operation. See chapter
5.1.11.14.
There is another input called VARIO PRIORITY. When this input is activated by
grounding the appropriate wire the unit will change to Vario immediately. This
input wire is set open (not grounded) as a factory default on delivery.
