their radio button is checked; for example the "created" signature. If the document already has
multiple signatures, the user must select one to check.

The signature program must be installed.
Signatures can only be checked or created if 21 CFR Part 11 functionality is enabled.

Proceed as follows:
Open the document to check.
Open the "Verify digital signature" dialog in the operating software by selecting
File > Verify

Check the radio button next to the signature you want to check.
Click
Verify
. The program begins to check. The result is displayed in a message window and
indicates whether the signature is authentic or not. "Good signature from..." indicates that the
signature is authentic.
