I had to replace my Raven Cruizer and went with the CR7, which is mainly used for guidance.  I use this tractor for NH3 application and, with the help of Raven tech support, I can paint the screen when the SCS440 switch is on.  The NH3 bar that I have been using has three sections.  When I shut off one or two sections, the screen still paints all three sections.  Is there a setting to shut off the paint on the screen when I shut off a section on the 440?  I had the CR7 set on section control and I think would work fine once I have all of the tractor to NH3 bar measurements entered correctly.
