We purchased brand new 323 and trying to use 2d grade and assit mode, icons on bottom panel are not illuminated and when in settings pretty sure I have everything enabled but still can't access the portion of inputting grade numbers or even putting in a bench mark
I had same issue last summer when I rented a 323 long front. I can't remember exactly what had to be turned on, and it wasn't very easy to figure out. You'll probably want to contact the dealer and hope there is someone there who knows the system.
