Checking Your System with
DigiTest
Before you use Pro Tools, you may want to run
the DigiTest diagnostic application to ensure
that all Pro Tools|HD cards in the system are rec-
ognized, installed in the proper order, and have
valid TDM FlexCable connections.
The DigiTest utility performs diagnostic tests on
the Pro Tools cards in your system. If DigiTest
reports that any of your cards have failed, click
the Info button next to that card. Write down
the information that appears and report it to
your local dealer or to Avid Customer Success.
