Convergence

CON

Press 4 from the Convergence Menu to display the ACON Auto-Convergence Menu. The menu displays five ACON options for selection and shows the most recent ACON status message (if there is one).

Note: The ACON Auto-Convergence Menu is available only if the ACON module is installed.

Before using ACON for the first time it is important to understand how ACON operates. ACON consists of two primary components; a Locator Assembly, normally mounted to the front of the projector, and an ACON Control Board, located inside the projector. The Locator Assembly includes a photosensor which, via two stepper motors, can monitor any point on the display screen. The ACON Control Board controls the viewing position of the photosensor. During automatic convergence, small red, green, and blue targets are displayed for viewing by the photosensor. Data from the photosensor is analyzed and convergence adjustments are made accordingly. The lens of the Locator Assembly can be observed to move about as each convergence zone is analyzed and adjusted. No user intervention is required.

WARNING: IN RARE INSTANCES, FLASHING LIGHTS CAN TRIGGER AN EPILEPTIC SEIZURE. DURING ACON OPERATION PERSONS WITH EPILEPSY SHOULD NOT WATCH THE SCREEN.

Automatic Convergence – Full, Touchup, and Center Only

Options 1, 2 and 3 in the ACON Auto-Convergence Menu provide selection of three automatic convergence routines; ACON (full), ACON (touchup), and ACON (center only). If the image has never been converged or is poorly converged, select option 1, ACON (full). If the image has been previously converged and only minor touch-up is required, select option 2, ACON (touchup). If the red or blue image has shifted position and is not registered with the green, select option 3, ACON (center only).

Note: It is important to have a good lighting environment when using ACON. Dimmed incandescent lighting is preferred over fluorescent lighting. Avoid shadows on the screen.
