its normal operating temperature), it can be turned on again by

• The WARNING indicator continues to blink even after the temperature inside the
projector returns to normal. When the projector is turned on again, the WARNING
indicator stops blinking.
Then check the items below.
– Did you provide appropriate space for the projector to be
ventilated? Check the installing condition to see if ventilation
slots are not blocked.
– Is the projector not installed near the ventilation duct of air-
conditioning equipment that may be hot? Install the projector
away from the ventilation duct of air-conditioning equipment.
– Are the air filters clean? Clean the air filters periodically or
replace it with a new one.
