Operation Manual

Hi @defaultsiw11d41o7s3 

I'm not sure that the manual is still online for Acrobat Pro 9, which reached end of life on June 26, 2013. I couldn't find it.

This is the PDF manual for Acrobat DC from November 2019. It is the last PDF manual for Acrobat.

Adobe has decided to stop making PDF reference manuals. All help is now online only.

You might check online to see if you can find a Classroom in a Book, Bible, or QuickStart Guide for your version.

I hope this helps.
