Replacing Parts in the Oscilloscope
To order a part in the material list, quote the Hewlett-Packard part
number, indicate the quantity desired, and address the order to your
nearest Hewlett-Packard Sales Office.
To order a part not listed in the material list, include the model
number and serial number of the oscilloscope, a description of the
part (including its function), and the number of parts required.
Address the order to your nearest Hewlett-Packard Sales Office.
To order using the direct mail order system, contact your nearest
Hewlett-Packard Sales office.
Within the USA, Hewlett-Packard can supply parts through a direct mail
order system. The advantages to the system are, direct ordering and
shipment from the HP Parts Center in Mountain View, California. There is no
maximum or minimum on any mail order. (There is a minimum amount for
parts ordered through a local Hewlett Packard Sales Office when the orders
require billing and invoicing.) Transportation costs are prepaid (there is a
small handling charge for each order) and no invoices.
In order for Hewlett-Packard to provide these advantages, a check or money
order must accompany each order. Mail order forms and specific ordering
information are available through your local Hewlett-Packard Sales Office.
Addresses and telephone numbers are located in a separate document
shipped with the instrument.
