•During this period of 2 minutes in the standby mode, the intake fan and exhaust fan rotate to cool the lamp.

•The air outlet fans rotate faster as the temperature around the projector rises.

•Do not unplug the power cord while the STATUS indicator is blinking. Unplugging the power cord immediately after use may cause a breakdown.
