The four buttons grouped in the center of the hand controller, as shown in the image above, are used to control the ROV camera.
The buttons at the top and bottom of this group control the ROV camera upward and downward tilt. The upward camera tilt button is labeled with a camera icon and an arrow pointing upward. The downward camera tilt button is labeled with a camera icon and an arrow pointing downward.
The buttons on the left and right side of this group control the ROV camera near and far focus. The camera focus near button is labeled with a fish icon, and the camera focus far button is labeled with a mountain icon.
Holding any of the buttons down in this group will continue the action. For example, if the camera tilt up button is pressed and held down, the camera the will continue to move upward until the button is released, or until the camera reaches the end of its movement range.
