Self-diagnosis display
There is a self-diagnosis display on the side of the projector. Self-diagnosis display will automatically display the
value of the input supply voltage, or details of errors or warnings when they occur. (
The following list shows the alphanumeric symbol that is displayed when an error or a warning has occurred and
its details. Confirm “Action number”, and follow the measure in “Measure for error and warning” (
The input supply voltage is displayed only with the numeric value.
