NOTE: Normal 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
might still be considered acceptable; in no case should a unit fail
to meet limit specs.
Specifications are typical; individual units might vary. Specifications are
subject to change and improvement without notice.
