Lens mount
components
The lens mount provides a means of securing a projection lens to the projector. Components include
the lens boot, lens mount barrel, and the lens mount offset.

Removing the lens boot

The lens boot is a critical part of the projector's electromagnetic interference (EMI) enclosure and is
required to meet FCC standards for radiated emissions. It also helps to keep out dust and foreign
materials.

2. Disconnect the harness.
3. To release the lens boot, remove eight screws securing the two boresight indicator brackets.
4. Carefully pull the lens boot off of its locating pins and around the bayonet locking plates.
5. Replace the lens boot and/or the boresight indicator brackets.
6. To re-install, repeat these steps in reverse order.

Replacing the offset motor

The offset motor provides a means of adjusting the position of the projection lens using motorized
controls. It contains both the horizontal and vertical offset motors.
