Adjusting Flight Altitude

How do I adjust the flight altitude I want before takeoff? We have everything setup but have yet to flight test using DD. I just want to make sure I’m flying at the altitude I want. Also, how can we override DD if there’s a problem and we need to take manual control of the aircraft? Thanks

If you click the settings button that looks like a gear in the bottom left you can adjust altitude.

If you switch to P mode on the RC you can always take control of the drone. If you want to cancel the mission you can also push the home button in the bottom
Right to come home.
