1.2 Electrical Parts
Electrical parts are indicated with “symbol + number (two or three digits)” in this manual.
While most parts are shown with a sequence number, some parts are organized by categories
of functions and units. When only one part exists in a category, the part is indicated only by
a symbol without a number.
Note
“Layout of Electrical Parts” in the Parts Catalog uses the same symbols as used in this
manual.
