Page 3 Visual Systems VT45 Installation Data Desktop and Ceiling Mount Normal Projection Position The normal projection position for the VT45 is with vertical lens shift approximately halfway between Zero Degree Projection Position and Maximum Vertical Offset Projection Position. See diagrams below. Rev 1.3 Lens Shift Range for Desktop and Ceiling Mount Application The diagrams below show the location of the image position in the lens. The lens can be shifted within the shaded area as shown using the normal projection position as a starting point. Note: Maximum range in certain directions might not be obtainable due to the rounded off area near the edge of lens. See diagrams below.
