9. Appendix
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.
