Make sure that you have the Rx plugged into the right port and the Tx/Rx are bound.
What are you plugged into on the RX and Naza?

I am plugged into #8 on the Futaba RX and X2 on the Naza.
Ok, now you know you have to set the RX to use S-Bus right?
Is this a new setup? if so I can direct you to alishanmao on YouTube, he has some very good videos on how to set up that exact radio..

Just make sure your radio is set for Acrobatic mode and not Helicopter, DJI does state this in the manual. It can be confusing to set up, but I am sure you can do it.. Take your time, watch the videos, pause, rewind and keep watching till you set it like Ali has. You will learn what the function is for and why it is like that.
I think I may have watched one or more of his videos before. Does he show how to make a completely independent failsafe switch? If I recall correctly, his failsafe set up depends on your being in a particular flight mode, meaning that I'd have to have the presence of mind to be in the correct flight mode before triggering failsafe.
I was looking at the video linked below to help me set up a completely independent failsafe mode that allows you go go into failsafe regardless of flight mode. This guy calls it "forced."
