Red LED behavior and projector errors

If the projector is not functioning properly and the LED is blinking red, con- sult Table 4 to determine a possible cause. There are two-second pauses between the blinking cycles. Visit our website for more details on the red LED error codes.

	Table 4: LED Behavior
Red LED Behavior		Explanation
One (1) blink		The lamp won't strike after five (5)
		attempts. Check the lamp and lamp door
		installations for loose connections.
Two (2) blinks		The lamp counter hours have exceeded
		lamp life hours. Replace the lamp and
		reset the lamp hours counter.
Three (3) blinks		The projector has shut down. Check to
		see if the lamp door is open. If the lamp
		door is closed, toggle off the projector
		and wait one minute, then toggle the pro-
