" All major subassemblies shall have separate manuals except in those
cases where individual subassemblies are physically very small or where
the circuitry is particularly inter-related with the next-higher assembly..
" All manuals shall contain an exposition section covering the theoretical
operation of the assembly.
" All manuals shall contain individual schematics, typical voltage and
current waveforms, resistance measurements, and other pertinent
reference information, including caution notes if special care is re-
quired in a particular evaluation.
" All manuals shall require cross-reference arrangements so a schematic
designation can be quickly translated to the actual physical location of
o The troubleshooting guide shall contain a complete physical definition,
showing the location of all test points, components parts, components
electrical designations (such as transformer terminal numbers), anode
or cathode designations of semiconductor diodes, all land and path routings
on printed circuit components, part number of components, and any other
" 'The manual shall show electrical test specificifications and test-operation
" Analytical procedures for any unusual troubleshooting techniques or
operations where the operator must be cautious to prevent damage to the
unit shall be included in the troubleshooting guide.
Development of the. Theory Section. The concept outlined in this section of
the manual begins with the basic design considerations and general operation
of a circuit of the same general type, and advances to the specific details of
the particular circuit of the assembly. The text is written on the level of a
skilled technician. The terminology and theory-of-operation explanations
assume comprehensive knowledge of electronics. The use of equivalent
circuits, partial sections of circuitry showing current flow and voltage
drops, and overall circuit operations are among the techniques used in the
The text does not offer a cookbook type approach, nor is it designed to teach
the fundamentals of electronics. Instead, it is directed toward explaining
the electronic function of the product and defining applicable parameters.
