If used by the Linked Time Lord Operator this lever initiates an emergency All Frequencies Alert to Gallifrey. This lever also serves a secondary purpose if the Symbiotically Linked Time Lord is drifting free in the Space/Time Vortex. In such a case a TARDIS will use the time contours to automatically lock onto the linked Time Lord. Once this link has been established a crewmember can pull the Extreme Emergency lever, and the TARDIS can rescue the Time Lord, materializing around him.
