Chapter 5 Backdating
Introduction
Introduction
Since this is the first edition of this guide, this chapter does not contain
any information for adapting this guide to apply to older instruments.
As engineering changes are made, newer instruments may have higher
serial prefix numbers than the ones shown on the title page of this guide.
These instruments may be supplied with a Manual Updating Changes
package containing the required information, or they may be supplied
with newer editions of this guide that contain information about adapting
that edition of this guide to older instruments.
If a Manual Updating Changes package is included with your Counter,
modify existing guide information or replace the affected pages as directed
in the pages of the Manual Updating Changes package. For additional
information, contact the nearest Agilent Sales and Support Office.
