    Compatibility with Screen Data of Other PT Models The screen data of the NT31/NT31C does not have complete upward compatibility with the screen data for earlier PT models. Consequently, when the data for an earlier PT model is converted for an NT31/NT31C use, partial modification may be necessary.
