Specify the users and their access permissions for each stored document. By making this setting, only users granted access permission can access stored documents.

To change the access privileges of a document's owner or another user with [Full Control] privileges for a document, use the [Change Access Privilege] setting of the document.
Select the document.
Press [Confirm/Change].
Press [Change File Info.].
Press [Change Access Privilege].
