Ok guys I just got a used 3pk with no manual and I need to know how to select differant models?And how do you change between newbie and pro and expert?

Download the manual here - its about 1/3 way down the page, you'll need it, its not complicated, but explaining everything would be a wot and prob wouldn't be explained as well as the manual does anyway -

Basic setup on almost last page - a kind of quick start guide for most commonly used features.
