Recall circuit

The recall circuit was a component of a TARDIS, part of the space-time element.

Thanks to it, the High Council of the Time Lords could recall a TARDIS on Gallifrey and place it in any position. According to the Fourth Doctor, until the presidency of Borusa, it had been used only twice in the history of the Time Lords. The third occurrence was the recall of the Doctor's TARDIS itself, summoned to deal with the second Omega crisis. The Doctor asked Damon to provide him another space-time element, preferably without a recall circuit. (TV: Arc of Infinity)
