Have newly built DJI F550 and new DX6i that was pre configured for the F550. 3 cell 11.1v 5000mah battery freshly charged on the F550. When I plug in the battery cable on the F550 first I get 2 short beeps, one long beep one red light flashes followed by several green flashes then a fast pulsing red/orange light. Having preselected the F550 memory position on the DX6i first I power it up with all switches forward except the trainer switch which I hold up till I receive the beep and Bind text in the display. When I release the trainer switch the beeps stop and bind text is gone with the display showing the DJI F550 icon and controls. No response to throttle. On the F550 the led keeps pulsing red/orange continues until I unplug the battery cable. Have attempted bind at various distances up to 15 feet from F550. I am a total noob at this so any and all suggestions appreciated.
