Adjusting the Screen Image
Projection image position adjustment (Lens shift)
The lens shift function can be used to adjust the position of projected images when the projector has been set up in places such as the following.
•When the projector is suspended from a ceiling
•When the screen is higher than the projector
•When the projector is at an angle to the screen so that people can sit directly in front to view the screen
•When the projector is on top of a desk or similar
The lens shift function can move the lens horizontally and vertically to adjust the image position without causing keystone distortion. Use the two lens shift dials to adjust the position of the projected images.
*At the time of shipment from the factory, the vertical lens shift position is set to the lowest position, so move it to the center position before carrying out adjustment.
Horizontal lens shift: The projector can be set up anywhere between the left and right edges of the screen.
Vertical lens shift: The projector can be set up anywhere from the top edge of the screen to half the height of the screen below the bottom edge.
Lens at maximum down (Can be shifted by a maximum of half the screen width)
Highest lens position
Lens at maximum right (Can be shifted by a maximum of half the screen width)
Lens at maximum left (Can be shifted by a maximum of half the screen width)
Lens at maximum up (Can be shifted by a maximum of one screen width)
*The dotted lines indicate the projection range from the lens center position.
*The lens cannot be shifted to the maximum vertical and horizontal positions at the same time.
Adjustment procedure

Turn the two lens shift dials to adjust.
When the lens shift dial is turned, a point of resistance will be felt. This indicates the approximate center point for the range of adjustment. In addition, if the lens shift dial becomes hard to turn further and the image position stops changing, no further adjustment is possible.
If the projected images are tilted horizontally, use the left and right front adjustable feet to adjust the projector so that it is level.
