PAF switch Matrice 210

The Matrice 210 is reported as being supported for use with Pix4dcapture. I was able to create a flight mission, and connect to the drone. I received an alert that the PAF switch is not in the F position. The controller only has positions for P-A-S. Does anyone have a suggestion on what to do in this situation. I was using the Android version of the app on a Samsung Galaxy S20. Thanks
