Spirit System

Hi
I want to set the rescue mode to the gear switch on my DX8.
I can assign aux 2 to the switch in system setup/ switch select but very unsure what to set up in the function/monitor or mixing to make it work correctly? Or am I completely wrong in what I am proposing?
Any help please

Dx8 has a error when in switch select on dx8 mix is the gear switch. No mixing required

Thank you, all works now , set a -70 in stabi for normal rescue and when I activate the gear switch I get a maximum 10 degree of positive pitch which should be OK for my sport flying.
Just need to maiden now with the spirit on board.
