∗1 _{The projection distance is the distance from the front edge of the projection lens to the screen.}
2. Floating mechanism
The floating mechanism corrects for distortion between 30" to 60". At time of shipment, it is optimized for a
diagonal of 37" (including 4.5% overscan), but the floating mechanism should be adjusted if the projection size
is different and image distortion becomes prominent. Recommended values for different projection sizes are
given below, but adjustments should be made such that image distortion is minimized.
