SECTION VI
REPLACEABLE PARTS
6-1. INTRODUCTION.
6-2. This section contains information for ordering
parts, Table 6-1 lists abbreviations used in the
parts list and throughout the manual. Table 6-3 lists
all replaceable parts in reference designator order.
Table 6-2° contains the names and addresses that
correspond to the manufacturer's code numbers.
6-3. ABBREVIATIONS.
6-4. Table 6-1 lists abbreviations usedin parts list,
schematics and throughout the manual. In some
cases, two forms of abbreviations are used, one in
all capital letters, and one in partial capitals or no
capitals, This occurs because the abbreviations in
parts list are always all capitals. However, in the
schematics and in other parts of the manual, other
abbreviation forms with both lower case and upper
case letters are used.
6-5. REPLACEABLE PARTS LIST.
6-6. Table 6-3 is a list of replaceable parts and is
organized as follows:
a. Electrical assemblies and their components in
alphanumerical order by reference designation.
b. Chassis-mounted partsin alphanumerical order
by reference designation.
¢. Miscellaneous parts.
d. Illustrated parts breakdowns, if appropriate.
The information for each part includes:
a. The Hewlett-Packard part number.
b. The total quantity (Qty) in the instrument.
