Just bought a new savage xl flux and cant get it to set up the ecs. I follow the very vague directions hold the set up button push the power button but the led only flashes green slowly. No red led no tones no nothing no matter how long I hold the set up button. I have brand new batteries with a full charge. I have tried to find a video on youtube but all of the videos are over 5 years old lol. Anything anyone might know to help get this thing going would be awesome, I'm starting to get pretty pissed.
