When this small box is plugged into the Control Console it disconnects the entire co-ordinate sub-system of a TARDIS, which results in the TARDIS being removed from the normal dimensions of time and space and being relocated outside of Normal Space. Normally it is impossible to alter the coordinates once the TARDIS has activated the Spatial Drive, but the Emergency Unit is the exception to this limitation. The Unit can be used to remove a trapped TARDIS from a dangerous environment or course through the Vortex, but runs the risk of trapping it in the Land of Fiction (located within Conceptual Space). For this reason the Emergency Unit has a built in timer to warn the operator to log in the coordinate subsystems and leave as soon at the Time Rotor's Energy Storage Unit is charged- usually 12 minutes. After the Time Lords dismantled the Land of Fiction it is possible to travel through the void of conceptual space as long as one doesn't try to materialize until after one has left.
