I have a spektrum DX6i transmitter and an AR636 reciever, I am following all the undoing steps for the receiver and it won't. Bind. I insert the binding plug, connect the flight battery, then step away at least 6 feet (recommend by Spektrum Support), power on transmitter in bind mode, I get a series of flashes that are different than the binding flashes, then the light on the reciever goes out. I then remembered be the bind plug and try to go through different steps to test or preflight the setup with no response. Any help here would be great. Thanks
