Projection distance formulas
Any other projection distance can be obtained according to the screen dimensions (m) by using the following calculations.
The calculated distance may contain a certain error.
If you want to calculate the projection distance with projected image size SD (unit: inch) by substituting, please assign 0.0254
times to the SD value.
4:3 aspect ratio
16:9 aspect ratio
16:10 aspect ratio
Screen height (SH)
= 0.6 × SD
= 0.490 × SD
= 0.530 × SD
Screen width (SW)
= 0.8 × SD
= 0.872 × SD
= 0.848 × SD
Minimum distance (LW)
= 1.0609 × SD - 0.0294
= 0.9632 × SD - 0.0294
= 0.9371 × SD - 0.0294
Maximum distance (LT)
= 1.7098 × SD - 0.0319
= 1.5523 × SD - 0.0319
= 1.5103 × SD - 0.0319
Adjusting adjustable feet
Lift the front of the projector and press the feet lock latches on both side of the projector.
Release the feet lock latches to lock the adjustable feet and rotate the adjustable feet to a proper height and tilt.
Extend the adjustable feet by rotating in the direction shown in the figure and retract by rotating in the opposite direction.

Adjustable range
Adjustable feet : 34 mm (1-11/32")
Maximum tilt angle: 8°
Attention
f
Heated air is expelled from the air exhaust port while the lamp is lit. Do not touch the air exhaust port directly when adjusting
the adjustable feet.
Adjusting the position using the vertical lens shift function
If the projector is not positioned right in front of the center of the screen, you can adjust the vertical position of projected image
within the shift range of the lens.
When you rotate the vertical lens shift dial clockwise (counterclockwise), projected image will move upward (downward).
