Info
• If the temperature warning indicator blinks and the projector enters the standby mode, the temperature
warning indicator starts to illuminate. Check whether any of the ventilation holes are blocked (see page 9)
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
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.
• Do not unplug the power cord after the projector has entered the standby mode and while the cooling fan
is running. The cooling fan runs for about 90 seconds.
The lamp does
not illuminate.
• The lamp is shut
down abnormally.
• Disconnect the power cord from
the AC outlet, and then connect it
again.
