Ordering Replaceable Parts
Listed Parts
To order a part in the parts list, quote the HP part number, indicate the quantity desired, and
address the order to the nearest HP Sales Office.
Unlisted Parts
To order a part not listed in the parts list, include the instrument part number, instrument
serial number, a description of the part (including its function), and the number of parts
required. Address the order to the nearest HP Sales Office.
Direct Mail Order System
Within the USA, Hewlett-Packard can supply parts through a direct mail order system. There
are several advantages to this system:
e Direct ordering and shipping from the HP parts center in California, USA.
e No maximum or minimum on any mail order. (There is a minimum amount for parts
ordered through a local HP sales office when the orders require billing and invoicing.)
e Prepaid transportation. (There is a small handling charge for each order.)
e No invoices.
In order for Hewlett-Packard to provide these advantages, please send a check or money
order with each order.
Mail order forms and specific ordering information are available through your local HP sales
office. Addresses and telephone numbers are located in a separate document shipped with
the manuals.
Exchange Assemblies
Some parts used in this instrument have been set up for an exchange program. This program
allows the customer to exchange a faulty assembly with one that has been repaired,
calibrated, and performance-verified by the factory. The cost is significantly less than that of
anew part. The exchange parts have a part number in the form XXXXX-695XX.
After receiving the repaired exchange part from Hewlett-Packard, a United States customer
has 30 days to return the faulty assembly. For orders not originating in the United States,
contact the local HP service organization. If the faulty assembly is not returned within the
warranty time limit, the customer will be charged an additional amount. The additional
amount will be the difference in price between a new assembly and that of an exchange
assembly.
