Adjust Left and Right Boresight

When performing these adjustments the goal is to balance the tilt of the lens mount to compensate for screen to
projector tilt, but also to precisely maintain the original factory settings of the lens mount axial position.
1. Loosen the horizontal locking screw.
2. Extend the lens focus completely.
3. Adjust the Focus using the focus knob to retract the lens. Watch the image at the left edge of the screen
until it comes into focus. If the entire screen is in focus, proceed to step 7.
