The method of numbering used throughout the unit includes the
assignment of reference designations (electrical symbol numbers) to
identify: assemblies, subassemblies, modules within an assembly, and
discrete components. An example of the unit numbering method is as
follows:
Subassembly Designation A1
Identify from right to left as:
On the main chassis schematic, components which are an integral part of
the main chassis have no subassembly designations.
The use of partial reference designations are used on the equipment and on
the manual illustrations. This partial reference designation consists of the
component type letter(s) and the identifying component number. The
complete reference designation may be obtained by placing the proper
prefix before the partial reference designation. Reference designation
prefixes are included on the drawings and illustrations in the figure titles
(in parenthesis).
