Stattenheim remote control

A Stattenheim remote control was a control disk (TV: The Two Doctors) used by Time Lords to control their TARDISes.

The Rani (TV: The Mark of the Rani) and the Second Doctor (TV: The Two Doctors, AUDIO: The Black Hole) each had a Stattenheim remote control linked to their TARDISes, as did, who created one to retrieve his. (PROSE: First Frontier) The act of whistling was not technically required, but was useful to focus the mind to "call" the TARDIS to the user's location. (PROSE: Timewyrm: Exodus)

The Second Doctor stored it in the teleport control of his console which gave dual control of his TARDIS to other Time Lords. (TV: The Two Doctors)

When the Sixth Doctor asked the Second Doctor where he had got a Stattenheim remote control, the Second Doctor said that "Some of us have earned these little privileges." (TV: The Two Doctors) According to one account, the Second Doctor had been granted his remote control by the Celestial Intervention Agency. (PROSE: World Game) According to another account this remote was given to him by who stole it from Pavo, in order to get the Doctor away from himself. (AUDIO: The Black Hole)

Following the defeat of Chessene and the Sontarans' plans to use the Kartz-Reimer module, the Second Doctor held the Stattenheim remote control and whistled. His TARDIS then rematerialised at the Spanish hacienda he was in. (TV: The Two Doctors)

The Master once tried to steal the Second Doctor's remote control. (GAME: Destiny of the Doctors)
