HOW TO USE THE IPB
GENERAL
This IPB is compiled following the organization and nomenclature of the engineering drawing structure.
MAJOR ASSEMBLY LOCATOR (When Applicable)
The Major Assembly Locator (first illustration) is an index that
provides a description and a figure reference for all illustrations used in this manual.
INDENTED PARTS LIST
This manual identifies each assembly being broken down
(figure reference callout), and all parts of that assembly.
Further breakdown of an assembly is shown by an asterisk(*)
preceding the item callouts in ttie Description Column. The
number of asterisks preceding an item is used to denote the
subordination of that item with respect to the Major Assembly.
A single asterisk preceding1!n item description indicates that
the item is part of the major assembly being illustrated. Items
that are subordinate to single asterisks items, are denoted by
two asterisks(**) and immediately follow the related single
asterisk item. Additional asterisks are used, as required, to
denote further subordination. This system of part identification, provides a means for the user to identify the next
higher assembly item and make alternate selections for parts
when the required replacement part of assembly is not
immediately available.
COLUMN CALLOUT DESCRIPTION
Figure and Item - Indicates the figure number and item
number of each part.

Description - Lists the name of the part and pertinent
specifications (when required). Asterisks preceding the
description denote the subordination of the part to the next
higher assembly.
DEC Part No. - Lists the Digital part ordering number. A blank
in this column indicates a Digital part number was not
assigned at the time of publication.
ECO Cut-In - The notation at the top of this column indicates
the ECO level of the system (option), at which the IPB was
initially prepared. Subsequent ECO level designations, that
modify existing parts or add ·new parts to the device, are
inserted in the ECO Cut-In column next to the part that is
added or modified.
Used On Code - Letters in this column correspond to the
variation codes assigned in Figure 1. Parts with an Alpha
notation(s) are used only in those option variations. A blank
indicates that the part is used on all option variations.
Ref Fig No. - A cross reference between illustrations. For
each Major Assembly, the number in this column denotes the
figure of the next higher assembly. For all subassemblies, the
number in this column denotes the figure showing additional
detailed breakdown.
PART NUMBER/PART DESCRIPTION SORT SECTION
Parts are sorted both numerically and alphabetically by
description, referenced to a location within the IPB, by figure
number and item number.
