Info<br />
• If the TEMP. (temperature warning)/STATUS indicator illuminates, and the projector enters Standby<br />
mode, follow the possible solutions above and then wait until the projector has cooled down<br />
completely before plugging in the power cord and turning the power back on. (At least 10 minutes.)<br />
• If the power is turned off for a brief moment due to power outage or some other cause while using<br />
the projector, and the power supply recovers immediately after that, the LAMP indicator will<br />
illuminate in red and the lamp may not be lit. In this case, unplug the power cord from the AC outlet,<br />
replace the power cord in the AC outlet and then turn the power on again.<br />
• The cooling fan keeps the internal temperature of the projector constant and this function is<br />
controlled automatically. The sound of the cooling fan may change during operation because the fan<br />
speed may change and this is not a malfunction.<br />
