I upgraded to a used FM-750 to get a more user-friendly monitor.  I have all of the wiring hooked up and went thru all of the settings that I can think I need to do.  It came up on my screen that I need to get newer firmware installed for the autosense.  I pulled the NAV II out and getting it updated at Ag Express.  Are there any other calibrations that I need to do?  I didn’t get a manual with the 750, but did find a user manual Online that I saved.  Thanks.
