Radio Calibration Faliure - Radiolink Pixhawk

Dear all,
I got a new Radiolink Pixhawk flight controller and connect my Radiolink R9DS to it .
But when i am trying to make radio calibration on Mission Planer , i cant do it.
When i am playing pitch and yaw on transmitter , i can see different reaction on screen ( radio bars on Mission planner ) and also error voice from pixhawk’s buzzer.

I cant find the problem and the reason of this error.

Please can you help?

Thanks and regards
Gökhan
