With your Tx trigger in neutral, press the Set button. The LED will turn on for about 1 second while it is setting the neutral point. Once the LED turns off, pull full throttle, then push full brake, then back to neutral. When the LED turns back on again, you should be ready to go with the default settings (Turbo -- .55 sec, Brake Min -- 0, Brake Max -- 100, Freq. -- 2KHz, Start Circuit -- off, Drag Brake -- off).
Programming the thing is a whole other story. PM me if you want me to send you the instruction PDF.
