MANUAL CHANGES
7-1. INTRODUCTION
7-2. This section contains information adapting this
manual with serial prefixes other than that listed on
the title page. This manual applies directly to instru-
ments with serial prefix numbers listed on the title
page. Refer to Section I for additional important
information about serial number coverage.
7-3. MANUAL CHANGES
7-4. As engineering changes are made, newer instru-
ments have serial numbers higher than those listed on
the title page of this manual. Instruments having serial
prefixes higher than those listed on the title page of
this manual are covered in a "Manual Changes" sheet
included with this manual. If this change sheet is
missing, the information can be supplied by any
Hewlett-Packard Sales and Service Office listed at the
back of this manual.
7-5. If your instrument's serial number prefix is
lower than that listed on the title page of this manual,
this manual must be modified to correctly apply to
your instrument. To determine which changes must
be made to this manual, locate your instrument's
serial number prefix in Table 7-1 and make the
indicated changes.
