Locked out distributor...

I'm pretty sure if I set both the start and step at zero when I start it for the first time it will be 4 degrees retarded like the instructions say. I'll then warm up the car and advance it 4 degrees... Back to its normal setting.. and as I understand it as soon as I give 12 volts to the trigger wire it will drop it any amount that I set the step for and will follow up and down that curve..
