Adobe Acrobat 7 Professional - Manual (Page 729)

Viewing permissions for a Digital Edition
All Digital Editions contain permissions set by the publisher that specify how many times
you can print and copy a Digital Edition, whether the document can be read aloud by
Acrobat, and when the document expires. These permissions are saved with the document
and downloaded when you borrow or purchase a Digital Edition.
To view permissions settings:
1. Open a Digital Edition.
2. Choose File > Document Properties, and then click the Security tab.
3. In the Document Security section of the Document Properties dialog box, click Show
Details.
Note: You cannot change the Security Method or Security Settings for Adobe DRM
documents.
