Service Before calling Hewlett-Packard or returning your RF section for service, please
read your warranty information. Warranty information is printed at the front
of this service guide.
Ordering Parts To order parts, contact the HP Service Center closest to you.
In any correspondence or telephone conversations, refer to the RF section by its full model
number and full serial number. With this information, the Hewlett-Packard representative can
determine whether your unit is still within its warranty period.
Determining Your RF Section's Serial Number
When a module is manufactured by Hewlett-Packard, it is given a unique serial number. This
serial number is attached to a label on the front frame or front panel of the module. A serial
number label is in two parts. (Refer to Figure 1-1.) The rst part makes up the serial number
prex and consists of four digits and a letter. The second part makes up the serial number
sux and consists of the last ve digits on the serial number label. The serial number prex is
the same for all identical modules; it only changes when a change in the electrical or physical
functionality is made. The serial number sux, however, changes sequentially and is dierent
for each module.
