Position the Projector

1. Position the projector at an
appropriate throw distance
(projector-to-screen
distance) and vertical
position. Ideally, center the
projector with the theatre
screen. If space is limited,
aim the projector slightly
off-center as shown in
Figure 2-2. This increases
side keystoning, but
reduces the horizontal lens
offset required.
2. Attach the supplied safety strap to the back of the projector and fasten it to its mounting surface. Use of the
strap is mandatory to prevent the projector from tipping when a lens or auxiliary lens mount is installed.
NOTE: Unlike film projectors, it is best to keep the projector lens surface as parallel to the screen as possible,
even if significantly above the screen center. When a particularly short throw distance combines with a very
wide screen, you may have to forfeit some aim and stay more parallel to the screen. In such cases, some lens
offset can reduce the keystone distortion.
