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 cable 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 ventilation holes if they are clogged with dust.

•Wait about 60 minutes until the inside of the projector becomes cool enough.
