Lens Mount Offset and Boresight Alignment

NOTES: 1) Projector must be fully assembled and
powered up in its final location. Install the auxiliary lens,
if it will be used at the site. 2) A 3/16" and 5mm Allen®
key are needed to make the required adjustments (Figure
2-13).
To ensure proper offset for your site and consistently good
focus in all areas of the screen, a primary lens must be
installed and its lens mount precisely adjusted in relation
to internal optics, as described below. In some applications
a wide converter lens (WCL) or anamorphic lens can be
used to accommodate changes between flat and "scope"
cinema displays.

2.6.1 Adjust Offset

Project an image with the primary lens only. The optional auxiliary lens mount, if present, can be mounted,
but moved aside by loosening the 4 bolts on the front cover and sliding the assembly out of the way. From the
CDP access the Lens Control>Lens Adjustment menu to adjust horizontal and vertical offset, as necessary to
display a square image on screen with minimal projector aiming error (Figure 2-14). Always adjust offset
before boresight. NOTES: 1) For best optical performance, minimize keystone error by using offset more than
aiming to the center of the image in off axis installations. 2) Horizontal and vertical offset can be adjusted via
the web user interface, Main>ILS.
