REQUIREMENTS COMPLIANCE

Unit is designed to fully meet with UL-1459 and FCC Rules, Part 15 and 68.

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.
