2-15. REPAIR MESSAGES
2-15
This section is a general description of repair messages and a cross reference
list of items identified for replacement to the maintenance procedure.
a. GENERAL DESCRIPTION
Repair messages are generated and displayed on the AN/USM-410 VDT when an error
is detected by the program.
The messages list items to be replaced in order of
probability of failure and identify the Items by reference designation, part number,
and name.
If the item to be replaced has no reference designation, the reference
designation of the next higher assembly is listed followed by XX. For example: the
HP94140A relay switch CCA, which has no reference designation and is part of the
matrix switch assembly 2A2A1O, is listed as 2A2A1OXX. The part numbers and names
are listed as an aid to further identify the item to be replaced. The module which
produced the repair message should be exercised after each replace action is
complete.
b. CROSS REFERENCE TO REPLACEMENT PROCEDURE
The following listing provides a cross reference of items to be replaced to the
replacement procedure.
The information is presented by module input code. The item
column identifies the item to be replaced by reference designation and part number.
The reference column identifies the paragraph where the procedure is found in this
manual.
Each list is in reference designation order and only provides a cross
reference to maintenance paragraphs.
The operator should follow the VDT screen
display for the proper sequence of repair/replace actions.
