Put the bind plug into the battery terminal and plug your battery into the aux. channel and turn the switch on. then you follow the procedure in the radio to bind it. note always put the reciever into bind mode before the radio. I'm not sure how the radio end works on the dx3s. check your manual.... all the info is there.
