HP 30020B Installation And Service Manual page 5

PRINTING HISTORY
New editions are complete revisions of the manual. Update packages, which are issued between editions, contain
additional and replacement pages to
be
merged into the manual by the customer. The date on the title page and back
cover of the manual changes only when a new edition is published. When an edition is reprinted all the prior updates
to the edition are incorporated. No information is incorporated into a reprinting unless it appears as a prior update.
The edition does not change.
The software product part number printed alongside the date indicates the version and update level of the software
product at the time the manual edition or update was issued. Many product updates and fixes do not require manual
changes, and conversely, manual corrections may be done without accompanying product changes. Therefore, do
not expect a one to one correspondence between product updates and manual updates.
