2.8 Optical

Alignment

Optical alignment is required when the throw distance changes or the pro-
jector cannot be focused using the focus controls. The projector is optically
aligned at the factory at a fixed screen size and a fixed projector-to-screen
distance. See Appendices F and G for the specific details needed for your
projector model and lens. If the throw distance has changed since the last
setup, proceed as follows:

Notes: 1) The projector must be warmed up for at least 45 minutes prior to
performing optical alignment. 2) Optical alignment is both a mechanical and
electrical adjustment. Electrical adjustments are stored in the current setup
memory. After alignment is complete, setup memories which were previously set
up (if any) must be set up again. Memory setup is explained in section 2.10. 3)
Factory alignment is performed using the internal crosshatch with a 61.8 kHz
signal applied.

It is recommended that optical alignment be performed using the projector’s
Guided Mechanical Setup tutorial. This tutorial displays step-by-step
instructions during the alignment. The instructions in this section require
use of the Guided Mechanical Setup tutorial.

To access and use the Guided
Mechanical Setup tutorial, turn on
the projector (
