Spektrum Binding red light

[Ben Marwood]

I need some advice please.
Trying to bind a Spektrum controller to my Spektrum receiver. I plug in the bind plug, then the battery but I only get a solid red light - not flashing. It won’t go into binding mode.
Does anyone know what is wrong?
Thanks in advance!
