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. (YO/all-06/27/96)
