Well glad ya got it figured out. I keep my old radios too for just in case circumstances. But if any of my single model or RTR radios give me troubles... I just toss em.
I can usually find a manual for just about anything. This is one of those times when I can't. Sorry you're having problems with it, but I would suggest throwing it in the garbage and buy you a Flysky GT3B if you can'tfigure it out. For $45 or so, you just can't beat it. 10 model memory, cheap...
