To protect your work from accidental changes, we recommend that use the Study Locking feature in both EMS and HFWorks. A locked study may be viewed but cannot be edited or changed. Of course, you can always unlock the study if you need to make changes. To lock your study simply right-click on the study name and select Lock. To unlock select Unlock.
