1. Focus adjustment

Loosen the screws (four) holding the projection lens in place, and adjust the eccentricity roller for focus

adjustment to change the focus between 27" to 55".

Projection distance [nm]

∗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 27" to 55". At time of shipment, it is optimized for a

diagonal of 40" (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.
