* For more information on "sleep mode", see page

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.
