Upper and Lower Lens Shift Position
• 
This projector is equipped with a lens shift function that lets you adjust the projection
height.
• 
Adjust it to match the setup configuration.
• 
The screen can be moved maximum the length of one screen vertically using the lens
shift.
Note
• 
Optimal image quality is produced with the projector positioned perpendicular to the
screen with all feet flat and level. Tilting or angling the projector will reduce the
effectiveness of the lens shift function.
Upper and Lower Lens Shift Position (Ceiling Mount)
When the projector is in the inverted position, use the upper edge of the screen as the base
line, and exchange the lower and upper lens shift values.
