6-1. INTRODUCTION
6-2. Ttns section contains information for ordering
replacement parts. Table 6-2 lists parts m alpha-
numerical order of their reference designators and
indicates the description (see Table 6-1 for abbrevi-
ations used) and -hp- stock number of each parts,
together with any applicable notes.
6-3. Miscellaneous parts associated with each as-
sembly are listed at the end of each assembly listing.
Others are listed at the end of Table 6-2.
6-4_ ORDERING lNFORMATlON
6-5. To obtain replacement parts, address order or
inquiry to your local Hewlett-Packard Field Office
(see lists at rear of tlus manual for addresses).
