Info
• If the temperature warning indicator illuminates and the projector enters the standby mode, check whether
any of the ventilation holes are blocked (see page 8) 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.
• The cooling fan keeps the internal temperature of the projector constant and this function is controlled
automatically. The sound of the cooling fan may change during operation because the fan speed may
change and this is not a malfunction.
The lamp does
not illuminate.
• The lamp is shut
down abnormally.
• Disconnect the power cord from
the AC outlet, and then connect it
again.
