something to contend with whenever you do a software upgrade. You would presume that an 'upgrade' [size=small](the most recent one)[/size] would already have the software settings as they would be for the former upgrade so the new upload will simply restore the factory defaults, as they should be up-to-date plus add the new feature/function changes.
So it's as simple as 'upload' all the current factory [size=small](aka default)[/size] settings for an unmodified Impact, then refer to your preferred personal settings [size=small](that you should have written down in a paper-file log book or on your computer)[/size] and walk through each mode/program and adjust each available adjustment setting as you prefer.
Then get out detecting, of course.
