1- select channel to adjust EPA of
2- Move control stick fully to one end of travel in direction wished to be changed and hold if needed.
3- Use data input lever up/dn to change value to desired amount. Do not overdo this without checking result, you can always go back and do more.
4- Move control stick in other direction if desired to change other end EPA also and use input lever to adjust.
5- Each end of each channel may be adjusted if desired/needed. Be SURE before doing this that you have made all mechanical adjustments that you can first.
6- Exit programming mode
This only effects the plane for the memory position you are working with, not the others.
