binding trouble
 

Please can anyone help, just got a 2nd transmitter DX3s an trying to bind it to my orange receivers, I had the DX3c before an they worked great, put in bind plug an flash quickly as normal but then it blinks a few times an the light goes of an then nothing
Any help would be much appreciated guys

Are you going to the bind function in the tx menu first? From what I remember you need to set tx to bind then turn on the rx. Hope this helps.
