Abort mission/emergency control on Phantom 4

I have only used Dronedeploy on a Phantom 3, where I can flip the flight mode switch to assume control in an emergency and retake GPS control. How can I do this with the Pha tom 4?

I simply flipped the attitude switch on the left side of RC - (back and forth once) to take over my P4. Think this is common on all of them if I am not mistaken.

Yes. That will set it in ATTI, but I guess thats the only choice?

You can switch to S mode to take manual control on the P4.
