Acrylic plate
Note: Dust, foreign particles and fingerprints attached on the acrylic plate and AF sensor lens may cause
deviance in the detected angle of keystone correction.
Even a very fine thread on the acrylic plate will generate deviance; therefore remove such thread
completely.
Wipe off dirt or dust by a cloth for cleaning glasses.
Pay utmost attention to the lens of the AF sensor, which is very delicate.
