NOTE: Precision Access allocates space for smart card usage and other useful functions in IS2000. Default and preferred setting is 'TRUE'.  Memory can be expanded by adjusting the Precision Access setting in the IS2000 Configuration Window and also by adjusting the card population setting in the Properties section in Hardware Manager for each controller.  (Controller Reset required.)
