Over-Temperature Protection
If the temperature inside the projector rises too high, the over-temperature protector will automatically turn off the lamp
with the STATUS indicator blinking (2-cycle On and Off.)
Should this happen, do the following:
• Unplug the power cord after the cooling fans stop.
• Move the projector to a cooler location if the room where you are presenting is particularly too warm.
• Clean the vents if they are clogged with dust.
• Wait about 60 minutes until the inside of the projector becomes cool enough.
