Over-Temperature Protection

If the projector inside temperature gets too high, the lamp will be turned off automatically and the status indicator will start to blink (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.
