Install the Primary Lens

The lens seals the projection head, preventing contaminants from entering the main electronics area. Do not
operate the projector without a lens installed. Install a lens plug when you install or transport the projector.
1. Verify the rear safety strap or rear hold down bracket is installed.
2. Rotate the lens clamp to the OPEN position.
3. With the UP label facing up, insert the lens straight into the lens mount opening all the way back, without
turning.
4. Move the lens clamp to the DOWN position to lock the lens assembly.
5. Remove the front lens cap.
6. On the TPC, tap Menu > Configuration > Diagnostics and
Calibration.
7. Tap Reference Calibration.

2.10 Install the Optional Anamorphic Lens

1. Install the M-MALM according to the instructions provided with the
kit. Ensure the primary lens is optimized first for best optical
alignment, offset and boresight.
2. Loosen the holding clamp on the auxiliary lens mount and adjust
rotation of the whole anamorphic lens so the image remains perfectly
square with anamorphic in and out.
3. Adjust location of anamorphic lens so the image does not shift left or
right with the anamorphic lens IN and OUT.
4. Adjust location of anamorphic lens so the image passes through the center as much as possible without
vignetting or reducing side or corner brightness, especially in wide angle projection.
5. With the anamorphic lens not in place, re-focus the primary lens. The goal is good focus at center and on
all sides. Now add the anamorphic lens and check focus again.
