Info
•If the temperature warning indicator illuminates, and the projector enters standby mode, follow the possible solutions above and then wait until the projector has cooled down completely before plug- ging 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 illumi- nate 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.
•The cooling fan keeps the internal temperature of the projector constant and this function is con- trolled automatically. The sound of the cooling fan may change during operation because the fan speed may change and this is not a malfunction.
•Do not unplug the power cord after the projector has entered standby mode and while the cooling fan is running. The cooling fan runs for about 90 seconds.
