6.3.2-1 Control of Critical Information Display

Control of large-screen group display systems should be such that critical information cannot be modified or deleted inadvertently or arbitrarily.

Additional Information:
The capability to change the display should be limited to designated users who operate according to pre-established procedures, upon command of a person in charge, or both. When users must make changes that are of interest only to them, a separate, remote display (such as a console VDU) should be provided.
