Preparation steps:
1. Ensure that the throw ratio of the installed lens matches the requirements of the application (projection distance and screen size).
2. Ensure that the correct lens parameters are activated. (See user guide of the Communicator chapter Installation > Advanced >
Lens parameters)
Note: Selecting the wrong lens parameters will result in an unexpected behavior of the lens when using macros for switching
between FLAT and SCOPE (change in picture size and focus).

5. Zoom the lens for maximum image on the screen (WIDE).
6. Is it possible to focus the center of the projected image?
If yes, the Back Focal Length is OK. Proceed with the next step.
If no, the Back Focal Length needs realignment. Proceed with the procedure "Back Focal Length adjustment", page 64.
7. Unlock and turn out the 4 set screws (reference 11 image 10-4) of the Lens Holder by 1 centimeter. Use a 10mm nut driver for
the lock nuts (reference 21 image 10-4) and use a 3mm Allen wrench for the set screws.
