NOTE: Nominal specs represent the design specs. All units should be able to approximate these, some will exceed and some may drop slightly below these specs. Limit specs represent the absolute worst condition that still might be considered acceptable; in no case should a unit fail to meet limit specs. (CJD/all-07/12/95)
