ACON Automatic ➤
Convergence
Press 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 dis-
play 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 selec-
tion 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.
