Stealth Mode

A TARDIS in stealth mode

Despite the Chameleon Circuit a TARDIS will still generate a field of tachyons that can tip off time aware races. And, while it is possible to hide a TARDIS from the observational powers of Gallifrey by placing it near a Naked Singularity, a Grey Immensity, a Phantom Star, or a Dwindler, some operators might wish to have a greater choice of locations. Stealth mode was developed as a way to hide TARDISes located in less exotic time zones.

When activated, Stealth Mode disables a TARDIS's connection with the Prime Eye of Harmony and deactivates all non-essential systems. Under normal circumstances it is easy for Gallifrey to get a signal lock on a TARDIS that has switched off all of its defence systems, however when running on only Emergency Power a TARDIS is virtually undetectable to everything, including Gallifreyan scanning devices. With the exception of basic life support, almost everything is made non-functional. As long as the discrepancy between the size of the exterior and interior is not too great, a TARDIS in Stealth Mode can pass as a normal everyday building. Even Time Lord visitors who materialize another TARDIS inside are unlikely to notice. A TARDIS can be switched from stealth mode to full power in as little as a few seconds, but this is very rough on the ship's systems and will cause many circuit overloads.
