The "manual" is a part of the CPS. It's the "Help" file found in the toolbar, and there are different layers depending on what highlighted items you click as you go through it. Somewhere the Help file info may be published, but I've never seen it in print.
Since the CPS is aimed at a radio technician knowledge level and not at consumer level, the software writers assume you are already familiar with programming advanced functions. Biggest problem for newbies is that if you don't understand the terminology within the help files and how it may apply to the Pro series, the Help files don't make programming easier. Nothing left to do but go through each section and click and read as you come to things, but be aware you can "brick" the radio by selecting the wrong 'click'.
