Not really sure at this point - most numbers seem to be correct, but not all letters are incorrect.? At this point I have not done much other than play with the menus and reseated a few boards.? I don't want to really tear into it if I'm going to wind up sending it back.? I *think* I remember reading at one time about the display units in these and I'm pretty sure that they have their own character generator - so the error could solely in it or in the connections from the main unit.? I'm mostly hoping at this point that someone else as run into this issue before.
