My 510 is here (after the mailman 1st drove by without delivering!) So I plugged in one battery, and the light is green. Not sure about the PCC? Do I put the 2nd battery in it and then plug it into my computer? And I guess I have to blow out atty's? I have the pre filled marlboro carts, I assume I don't need any liquid with those? All this excitement and I'm not sure what to do!
