Installation
Installing the Lens
4. Remove the foam plug from the lens cavity.
5. Carefully remove the lens and other installation hardware (in a small plastic bag) from
the shipping container.
6. Remove the rear cap from the lens. This protective cap is only used during shipping to
protect the lens from damage.
7. Remove the front cap from the lens.
8. Install the spring clip (provided with the lens) on the vertical lens shift adjuster retaining
slot, as shown. The clip reduces backlash in the vertical offset mechanism to keep it
from inadvertently moving after adjustment.
9. Insert the lens, with the small white label facing up, into the lens cavity. Ensure that the
notch on the vertical lens shift adjuster mates with the retaining slot on the projector,
as shown below. Otherwise, the adjuster won't work correctly.
