Priority Deactivation Code
This is a code chosen by the Time Lord operator allowing him to forcibly deactivate (or reset) specific parts of a TARDIS. Some systems (such as the Banshee Circuits) are immune to this unless the Automatic Systems Override is activated.
The following color code is used:
- Black: For information from the TV Series, including Dimensions in Time, and 1996 TV Movie.
- Blue: For information from the Novels and Audios including Target, Virgin, BCC, and Big Finish.
- Green: For information from 'licensed' reference sources such as the Technical Manual, Doctor Who Magazine, and the Role Playing Games.
- Red: For information from unofficial sources -The Faction Paradox series, behind the scenes interviews, author's speculation, and popular fan belief.
