4.5 Notice to Installer
Please use the following installation instructions to obtain optical performance from the Polar
Star Angular Reflective ALR
(Ambient Light Rejecting)
Screen Material.
1)
Angular-reflective material
is not compatible with ultra/short-throw projectors
2)
Ambient Light must not come from the same direction as the projector’s light
3)
Minimum Lens Throw Ratio of 1.5x image width
Since angular-reflective means that your projected image will reflect at the mirror-opposite angle, it is
important to position the projector so that the viewer will get the best performance.
Step1
: Establish the general “eye level” of the viewers
Step 2
: Set the appropriate projection level
Step 3
: Adjust your screen height level and projection angle
Input angle
(A)
= Output Angle
(B)
aligns with the viewer’s eye level
