You can access the help manual online, Adobe has posted the PDF Reference and PS language reference manuals and the Acrobat JS API Reference manual. You can also find the Mozilla JS reference manual online.
Look under the Developers community for Acrobat, and use the Knowledge base.
Thanks for your response. However, I did not understand it. When I went to the Developers Community for Acrobat, I did not find a link to a manual. WHen I searched for PDF Refernece, this resulted in a document wiht the specifications for PDF itself.
I am trying to get download a file which is the manual explaiing the Adobe Acrobat 9.0 Pro product.
There is no single "manual" explaining Acrobat (any release).
The reality is that a comprehensive "manual" would, in print, be more like volumes comprising an Encyclopedia set.
(...anyone remember those? )
What follows provides a bit of an overview of what Adobe provides as information resources to facilitate understanding through study, Q&A, and 'show and tell'.
Note that there are many non-Adobe sources of information and training that are most excellent as well.
There is the Acrobat Help documentation. This is installed when Acrobat is installed.
Adobe LiveDocs also provides Acrobat Help. There is a Help version for Standard, Pro, and Pro Extended.
This documentation is maintain as a living document set by Adobe.
There is the collected documentation available at Acrobat DevNet.
Even if you do not "develop" stuff, all of what is here belongs on the shelves of your 'eLibrary'.
It'll come into play as you continue to study for better understanding of Acrobat / PDF.
There is the Acrobat 'Help and Support' page.
This page has links to Acrobat LiveDoc Help.
There are the knowledgebase articles.
(Use Google — <search string> site:kb2.adobe.com)
Or, use the "Search Support" page to look for Acrobat related information.

As to the core "what PDF is" documentation; I guess that'd be ISO 32000-1:2008.
Prior to mid-2008, Adobe maintained the PDF References.
In mid-2008, PDF became an ISO Standard (32000-1).
This may be purchased from ISO; or, currently, Adobe has a free copy available.
For PDF Reference and Adobe Extensions to the PDF Specification —
At the bottom left of the above link you will find a link to the PDF Reference Archives.
