INTRODUCTION
5-2.
This
section of the
manual contains
a listing
of replaceable
components for this
instrument. The
first listing
contains a complete
breakdown
of all
the
major assemblies
followed by subsequent
listings that
itemize
the
components on each
major
assembly. An
illustration
accompanies
each major
assembly listing
to aid in locating the
listed
components.
5-3.
Assemblies
and
subassemblies are
identified
by
a
reference
designation
beginning with the
letter A
followed by a number
(e.
g.
,
A1 etc,
).
Electrical
com-
ponents appearing
on the schematic
diagram
are iden-
tified
by
their
schematic diagram
reference
designation.
Components not
appearing on the schematic
diagram
are consecutively
numbered throughout
the parts
list.
These
components
are
identified
with
whole numbers on
the
arrow call-out
illustrations
and by index numbers
on the grid illustrations.
Flagnotes
are used through-
out
the parts
list and refer to
special ordering
explan-
ations that
are located in
close proximity to the
flag-
notes.

sembly in
alpha-numeric
order. Subassemblies
of minor
proportions
are sometimes listed with
the
assembly of which they
are a part. In this
case,
the
reference designations
for the
components of
the
subassembly
may appear out
of
order.
b.
The

NO, column lists coordinates
which
locate
the designated part
on the associated
grid
illustrations.
c. The DESCRIPTION
column
describes
the
salient
characteristics
of
the component.
Indention
of
the
description indicates the
relationship to other
as-
semblies, components,
etc. In many
cases it is
necessary to
abbreviate in this
column. For ab-
breviations
and symbols used,
see
the
following
page.
d. The
ten-digit
part number,
by which the item

,
is listed
in the STOCK
NO. column.
Use this number when
ordering parts from the factory
or authorized
representatives.
e. The Federal Supply
Code for the item
manufacturer
is listed
in the MFR column.
An abbreviated list
of Federal Siqjply
Codes is included in the Appendix.
f. The part number
which uniquely identifies
the item

ordered
by description, the type number
is listed.
g.
The TOT
QTY column lists the total
quantity
of
the
items used in
the instrument and
reflects the latest
Use
Code, Second

assemblies, plug ins, etc. that
are not
always
part
of the instrument,
or
are
deviations from the
basic
instrument
model,
the TOT
QTY column lists the
total
quantity of the item
in
tliat
particular
assembly,
h. Entries
in the REC QTY
column indicate
the recom-
mended number
of spare parts necessary to
support
one to five instruments
for
a period of two
years.
This list
presumes an availability
of common
elec-
tronic
parts at the
maintenance site.
For mainten-
ance for one
year or more at
an isolated side,
it is
recommended that at
least one
of every part in the
instrument
be stocked,
hi the case
of optional sub-
assemblies,
plug ins, etc. that
are not
always
part
of
the
instrument,
or are deviations
from the basic
instrument
model,
the
REC QTY
column lists
the
recommended
quantity
of
the item
in that particular
assembly.
i. The USE
CODE column identifies
certain
parts
which have
been added, deleted
or modified
during
the production
of
the instrument.
Each part for
which
a Use Code
has been assigned
may be iden-
tified
with
a
particular
instrument serial
number
by consulting the
Serial Number Effectivity
List
at the
end of the
parts list.
Sometimes when
a
part is changed, the
new part can
and should
be
used as a replacement
for the original
part. In
this event a parenthetical
note is
added in the
DESCRIPTION
column.
