Remote receiver
Remote wore receivers in their earlobes which conveyed transmissions directly into their nervous systems, dramatically shaping the Remote around local broadcasts. These receivers were designed by Faction Paradox. (PROSE: The Book of the War) Imogen Tantry described a Remote receiver as having "smooth polymer whirls". (PROSE: De Umbris Idearum)
In an attempt to make Compassion more "human", the Eighth Doctor modified her receiver so that it only picked up signals from his TARDIS; this somewhat backfired as the signals from the TARDIS transformed Compassion from a Remote into something even more alien: the first Type 102 TARDIS. (PROSE: The Shadows of Avalon)
Compassion III's receiver was so integral to her self-image that it was recreated when she was resurrected in the City of the Saved. (PROSE: Of the City of the Saved...)
