• If the temperature warning indicator illuminates and the projector enters the standby mode, check whether

any of the ventilation holes are blocked (see page 

) 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

cord in the AC outlet and then turn the power on again.
