Emergency Manual Override station

Emergency Manual Override was one of the console stations on the bridge of the Starfleet starships, used to take control of the ship's computer during emergency situations.

On starships such as the USS Enterprise (NCC-1701-D), it stood right of center in the rear bridge console suite, between the Propulsion Systems and Environment stations. .

Captain Picard used the Emergency Manual Override station to access the ship's computer after the Bynars hijacked the Enterprise. 

By 2365, it was replaced by the relocated Environment station. (TNG Season 2)
