Frsky D8R-XP Failsafe issues

Hi All,

I am pulling out my hair trying to set the no pulse fail-safe mode for the the Frsky D8R-XP receiver. I have tried numerous times to rebind, pressing the FS button with the transmitter off, but it stubbornly refuses to change. I still have he last values for RC channels 1 - 4 (using mission planner status window to verify) and no failsafe is being triggered.

I have tried just about everything suggested on the forums, but they tend to be for other frsky receiver models. I have also removed the CH3/4 PPM jumper, with no change. I am waiting on the USB connector to arrive to see if a firmware re flash/update might help.

Has anyone managed to conquer this receiver.
