Today I took the transmitter outside and the controller and receiver. I held the bind button on the controller and connected the battery, then I held the bind button on the transmitter and turned it on about 10 feet away. It did not work; the transmitter bind indicator did not light up and the controller did not go steady red status. Something must be wrong with the transmitter. After replacing the battery in the transmitter, the screen has a message telling me to register the Spectrum transmitter when I turn it off. It never did that before I replaced the batteries. Since it is not mine, I am hesitant to do that. I am lost on what to do at this point, nothing seems to make it work.
