The standard configuration of the Rig is the External Monitor Position. This puts the cage straight ahead of the shoulder, allowing you to mount a monitor to the side of the cage and use that to view and frame your shot.
If you would like to change the positioning of the shoulder rest to the Camera LCD Position, here's how you do it:
Remove the shoulder rest by loosening the bolt connecting the base plate and the shoulder rest.
Now, remove the bolt and o-ring and insert them on the other side of the shoulder rest link, then tighten the bolt down.
You have now adjusted the shoulder rest, placing the cage and camera directly in front of you.
