7A-1. INTRODUCTION
This appendix contains information necessary to backdate the manual to conform with
the earlier PCB configurations. To identify the configuration of the PCBs used in your
instrument, refer to the revision letter (marked in ink)
on
the
component side of each PCB
assembly. Table 7A-1 defines the assembly revision levels
documented
in this manual.
As changes
and improvements
are made to
the
instrument, they are identified
by
incrementing the revision letter marked
on
the affected
PCA. These
changes are
documented on
a supplemental change/ errata
sheet which, when applicable, is inserted at
the
front of
the manual. To identify the configuration
the PCAs used
in your Generator,
refer to the revision letter on the component side of each PCA.
7A-2. BACKDATING INSTRUCTIONS
To backdate this manual to conform with an earlier assembly revision level, perform the
changes indicated in Table 7A-1. If this manual documents all
PCAs at
their original
level, no changes are necessary, and no changes will be indicated in Table 7A-1.
