Safety function

Hello,
I’ve been trying to access the safety button in the vehicle settings but I can’t get to any of the safety functions. The error message says it is not supported in this mode.

Configuration:
Ardupilot Rover 4.0

Thanks,

John.

I don’t get what are you asking about…
What mode are you using? What kind of safety function do you need?
