VERSION 2.0 2023-04-20 PAGE 3.2.3
Component Level
This number represents the level of a component in relation to the highest level parts list. In this case
the highest level parts list is the VX transmitter’s overall parts list, or the top block in the family tree
shown in Figure 3.2.1 on page 3.2.4, Figure 3.2.2 on page 3.2.5, or Figure 3.2.3 on page 3.2.6.
Components that are directly descended from the highest level parts list are component level 01. The
associated stock code and description for level 01 items appear in bold text in the reference designation
list, followed by their sub-assembly components, as applicable. Level 01 items are sorted
alphanumerically.
Components that are directly descended from component level 01 items are component level 02. The
associated stock code and description for level 02 items appear below their associated level 01
component, slightly indented, followed by their sub-assembly components, as applicable. Level 02
items are sorted alphanumerically
Component level 03 through 10 items, as applicable, descend similarly to component level 02 items,
with continuing indentations to identify each new level.
Stock Code
This number is Nautel's drawing number for Nautel manufactured parts, Nautel's configuration control
number for assemblies that are under configuration control management, or Nautel's inventory
management number for purchased parts. When a Nautel configuration control number (e.g., NAPA*) is
shown in this column, its sub-assembly reference designation items are listed below it.

This section includes Nautel part numbers only. It does not include original equipment
manufacturer (OEM) information (i.e., vendor part numbers). Some vendor information is provided in
the Responding to Alarms section of this manual, otherwise contact Nautel to order a replacement part
or to request assistance to find a suitable replacement.
