5.1 UNIT NUMBERING METHOD
The unit numbering method of assigning reference designations (-electrical symbol
numbers) has been used to identify assemblies, subassembli-es (and modules) and parts. An
example of the unit numbering method follows:
Subassembly Designation A1
Identify from right to left as:
R1 Class and No. of Item
First
(1)
resistor (R) of
first
(1)
subassembly (A)
As shown on the main chassis schematic, components which are an integral part of
the main chassis have no subassembly designation.
5.2 REFERENCE DESIGNATION PREFIX
Partial reference designations have been used on the equipment and on the illustra-
tions in this manual. The partial reference designations consist of the class letter(s) and
identifying item number. The complete reference designations may be obtained by placing the
proper prefix before the partial reference designations. Reference Designation Prefixes are
provided on drawings and illustrations in parentheses within the figure titles.
