Important Information
• 
If the temperature warning indicator illuminates and the projector enters the standby mode, check
whether any of the ventilation holes are blocked and then try turning the power back on. Wait until
the projector has cooled down completely before plugging in the power cord and turning the power
back on. (At least 10 minutes.)
• 
If the power is turned off for a brief moment due to power outage or some other cause while using
the projector, and the power supply recovers immediately after that, the lamp indicator will illuminate
in red and the lamp may not be lit. In this case, unplug the power cord from the AC outlet, replace
the power cord in the AC outlet and then turn the power on again.
• 
Do not unplug the power cord after the projector has entered the standby mode and while the
cooling fan is running. The cooling fan runs for about 90 seconds.
