Each assembly in the instrument is assigned an assembly identifier (for
example, MAIN or A3). The assembly identifier appears on the circuit board
outline on the diagram (see Figure 6-1), in the title for the circuit board
component location illustration, and in the lookup table for the schematic
diagram and corresponding component locator illustration. The Replaceable
Electrical Parts list is arranged by assembly in numerical sequence; the
components are listed by component number.

The schematic diagram and circuit board component location illustrations
have grids marked on them. The component lookup tables refer to these
grids to help you locate a component. The circuit board illustration appears
only once; its lookup table lists the diagram number of all diagrams on
which the circuitry appears.
