Notes:
1. 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.
2. This manual is based on the American (A) standard, and provides
information on regional circuit modification through the use of
alternate schematic diagrams or wiring diagrams, and information on
regional component variations through the use of parts lists. Design
and specifications subject to change without notice.
