Installation
To use a screen size not listed in this manual, check the screen size SD (m) and use the respective
formula to calculate projection distance.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a
slight 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.
Projection distance formulas
For S420W/S430W/S430Wi:
For S420/S430/S430i:
4:3 aspect ratio
16:9 aspect ratio
16:10 aspect ratio
Screen height (SH)
=SD(m)×0.6
=SD(m)×0.490
=SD(m)×0.530
Screen width (SW)
=SD(m)×0.8
=SD(m)×0.872
=SD(m)×0.848
Projection distance(L) =0.4625xSD-0.0339 =0.4188xSD-0.0339 =0.4085xSD-0.0339
The projection angle can be adjusted up to 10
degrees with the adjustable foot.
Lift the front of the projector up and press the
lock on the adjustable foot to release it.
Release the lock,the feet are then locked.
Rotate the foot to adjust the height and tilt
angle.
Keystone distortion of projected images can be
corrected by remote control or menu operation.
