Voice Override: Epsilon Actual

Voice Override: Epsilon Actual was a verbal command that immediately superseded a droid's primary programing. This override was activated by a verbal code, usually delivered in the form of a word or phrase. This command was programmed on C-3PO by Captain Jeremoch Colton aboard the Tantive IV to prevent the droids from speaking of Princess Leia Organa's presence, after she had recovered the plans for the first Death Star from rebel agents on Toprawa.
