Graupner MX-20 Failsafe problem

Guys I have a problem withthe mx-20

I'm using it for a mikrokopter, my receiver is the GR-32 (4 antennas), and the connection to the mikrokopter is via SUM channel (single cable).

I set the failsafe as described in the manual, selecting POS (position) for all channels, then I press SET and I get the message "Position Stored". But nothing happens if I turn off the radio. What is the problem ?

I think you have the newest firmware in gr-32 which doesn't work with mirkokopter failsafe properly. I have the same problem. In others receivers I downgraded the firmware in gr-32 I can't do that I don't know why
