Replaceable Parts List Updating (Manual Updates)
A "MANUAL UPDATES" packet is shipped with the manual, when necessary, to provide the most
current information available at the time of shipment. These packets consist of replacement and
addition pages which should be incorporated into the manual to bring it up to date.
Hewlett-Packard offers a Documentation Update Service that will provide you with further updates
as they become available. If you operate or service instruments of different serial prefixes, we strongly
recommend that you join this service immediately to ensure that you manual is kept current. For more
information, refer to the Documentation Update Service reply card included in this manual, or call:

MECHANICAL AND CHASSIS PART LOCATIONS AND REFERENCE DESIGNATIONS
Most mechanical parts are identified in Figures 6 to 10. These figures are located at the end of this
section. Major mechanical parts have reference designations that begin with the letters MP. To find the
part number and description of a mechanical part, find the part in one of the photographs or drawings,
and then look up the reference designation in Table 5. Mechanical hardware not shown in the figures,
such as screws, are listed under the part which they attach. For example, the screws that attach the
fan (Bl) to the rear panel are listed under Bl. Many of the cable assemblies have their reference
designation (for example, W21) and color codes (WHT/ORN) sUkscreened on the board assembly next
to the connector to which they attach. Since these cables are indicated in this way, their reference
designators are not called out in the photographs.
RECOMMENDED SPARES LIST
Stocking spare parts for an instrument is often done to ensure quick return to service after a malfunction
occurs. Hewlett-Packard has prepared a "Recommended Spares" list for this instrument. The contents
of the list are based on failure reports and repair data. Quantities given are for one year of parts
support. You can request a complimentary copy of the "Recommended Spares" list from your nearest
Hewlett-Packard office.
When stocking parts to support more than one instrument or to support a variety of Hewlett-Packard
instruments, it may be more economical to work from one consolidated list rather than simply
adding together stocking quantities from the individual instrument lists. Hewlett-Packard will prepare
consolidated "Recommended Spares" lists for any number or combination of instruments. Contact your
^
nearest Hewlett-Packard office for details.
