I think ur asking 2 different things. to reset the dvx u press the reset button and all settings INCLUDING scene files will be rest to factory settings.
To zero ur scene files (or customize them to whatever u want). go to menu> scene files and zero all the numbers and save it as 24p. Go to a different scene file on the dial/wheel and set ur personal settings and set that on to 24pa
** all the scene files (f1, f2 ect...) can be set to whatever u;d like
Go into the scene file that you want to reset. At the end, where you save (SAVE/INIT) the settings, select INITIAL. This will reset that scene file to the factory settings without changing the other scene files.
