SECTION VI
REPLACEABLE PARTS
61 INTRODUCTION
6-2 This section contains information for ordering re¬
placement parts. Table 6-4 lists parts in alpha-numeric order
by reference designators and provides the following informa¬
tion:
a. Reference Designators. Refer to Table 6-1.
b. Description. Refer to Table 6-2 for
abbreviations.
c. Manufacturer's Part Number or Type.
d. Manufacturer's Federal Supply Code Number.
Refer to Table 6-3 for manufacturer's name and address.
e. Hewlett-Packard Part Number.
f. Parts not identified by a reference designator
are listed at the end of Table 6-4 under Mechanical and/or
Miscellaneous. The former consists of parts belonging to and
grouped by individual assemblies; the latter consists of all
parts not immediately associated with an assembly.
6-3 ORDERING INFORMATION
6-4 To order a replacement part, address order or in¬
quiry to your local Hewlett-Packard sales office (see lists at
rear of this manual for addresses). Specify the following
information for each part: Model, complete serial number,
and any Option or special modification (J) numbers of the
instrument; Hewlett-Packard part number; circuit reference
designator; and description. To order a part not listed in
Table 6-4, give a complete description of the part, its func¬
tion, and its location.
