Identify the projector’s approximate front-to-back
center of gravity. Place your hands on each side of
the projector and gently lift it an inch from the surface
on which it is resting. Carefully adjust your grip on the
projector until it seems balanced from front-to-back.
Mentally note the apparent center of gravity.
➋
Identify the projector’s approximate side-to-side
center of gravity. Place your hands on the front and
back of the projector and gently lift it an inch from the
surface on which it is resting. Carefully adjust your
grip on the projector until it seems balanced from
side-to-side. Mentally note the apparent center of
gravity.
