Take into account that when the projector is tilted the Screen Width you have to fill in should be
larger than the physical screen width due to the keystone distortion of the projected image. How
much larger depends on the amount of tilt.
Due to production tolerances the real distances can differ by 2% from the calculated values.
For critical situations (fixed installs that use the lens at one of its extreme zoom positions) this
should be taken into account.
3.3 Lens installation
If no lens is installed the lasers of the Thor series projector can not be powered. The Standby button
en Light button will light up red. The Projector Toolset will also show the error message that there is
no lens installed.
