Calling
HP
Sales
and
Service
Offices
Sales and service offices are located around the world to provide complete
support for your cable TV analyzer. To obtain servicing information or to
order replacement parts, contact the nearest Hewlett-Packard Sales and
Service office listed in Table 8-1. In any correspondence or telephone
conversations, refer to the cable TV analyzer by its model number and full
serial number. With this information, the HP representative can quickly
determine whether your unit is still within its warranty period.
In general, a problem can be caused by a hardware failure, a software error,
or a user error. Follow these general steps to determine the cause and to
resolve the problem:
1. Perform the quick checks listed in “Check the Basics;” these checks may
eliminate the problem altogether, or may give a clearer idea of its cause.
2. If the problem is a hardware problem, you have several options:
l Repair it yourself, contact your HP Sales and Service Office to obtain the
most current test and maintenance information.
CAUTION
If it becomes necessary to return your analyzer to a Hewlett-Packard service
center, save any user-defined functions or measurement personalities to a
memory card. It may be necessary for the service center to load diagnostic or
measurement personalities into user memory which would over-write existing
programs, or memory could be erased during repair. Hewlett-Packard cannot
guarantee that the user memory will be preserved. Refer to “Saving and
Recalling Data from the Memory Card” in Chapter 3 of this guide.
l Return the analyzer to Hewlett-Packard for repair; if the analyzer is still
under warranty or is covered by an HP maintenance contract, it will be
repaired under the terms of the warranty or plan.
If the analyzer is no longer under warranty or is not covered by an
HP maintenance plan, Hewlett-Packard will notify you of the cost
of the repair after examining the instrument. See “Calling HP Sales
and Service Offices” and “How to Call Hewlett-Packard” for more
information.
