What are modes of Steering Gear?

This mode of steering is not done with a steering wheel but with a NFU Lever.
The NFU lever does not have any markings. As long as it is kept pressed, the rudder will continue turning and stop the moment the lever is released.
This mode is used when ships telemotor system fails. In that case, the NFU lever sends rudder setting directly to the Control Unit.
To return the rudder to the midship, the NFU lever will have to be pressed to the opposite side of the initial movement and kept pressed till the rudder is amidship.
