Identifying product versions
The Ultra short throw lens kit is designed with two types of installation accessories to fit the different
lens shift modules (LSM) on the projectors. Check the boresight of the projector to identify the version
of the lens shift module. This document provides installation steps for both types of LSMs.
Make sure the projector is turned off before checking the boresight.

target screen size.
3. Based on the projection screen size, calculate the setup dimension.
See the Lens specification table (on page 17).
4. Make sure the variation of the B value and the value in the Lens specification table are within
+/-1cm (+/-0.4 inches).
5. Make sure the variation of the M value and the value in the Lens specification are within
+/-1cm (+/-0.4 inches).
Lens specification table
The following table and image provides the lens specifications.
• P = Projector height
• A-P = From the top of the projector to the bottom edge of the screen
• L = From the front of the lens to the rear of the projector
• B = From the projector back to the projection screen
• C = From the lens front to the projection screen
• M = (A-P)+(H/2) = From the top of the projector to the center of the screen
