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.
