ACON Errors
➤
If ACON is installed and an error message occurs during automatic
convergence or Learn Screen, proceed through the following checklist.
❑ Is the ambient lighting appropriate for projection? A number of problems
could result during automatic convergence and/or Learn Screen if the
ambient lighting is too bright. Dimmed incandescent lighting is pre-
ferred over fluorescent lighting. If error messages such as "Sensor Lock
Failed: Low Signal" or "Learn Screen Failed: Insufficient Magnitude"
result, lower the ambient lighting, especially at the projection screen.
❑ Is the view path of the Locator Assembly completely unobstructed?
The view path between the photosensor lens of the Locator Assembly
and the entire screen must be completely unobstructed for proper
ACON operation.
❑ Has a Learn Screen been performed since the last projector configuration
change? Learn Screen must be performed if:
• The throw distance has changed since the last time Learn Screen
was performed.
• The ACON Locator Assembly mounting position has changed
since the last time Learn Screen was performed.
• The screen type has changed.
• The source has changed.
If the problem cannot be resolved, call your dealer for servicing.
