The temperature inside the projector is too high for some reason
or the outside air temperature is higher than the specified one. If
the problem is inside the projector, check whether the projector
is installed and operated normally, turn off the projector to cool
its inside, and retry projection. If the air intake or exhaust vent is
blocked, remove the obstacle. If the same warning occurs
again, the projector may be defective. Contact your dealer.

The lamp has burnt out. Replace the lamp with a new one. If the

cover
The lamp cover is open. Turn off the projector and unplug it from
the power outlet, then install the lamp cover and turn on the pro-
jector again.
If the lamp cover has been installed properly, the lamp cover
detection switch may be defective. Contact your dealer.

fan
The cooling fan or another component may be defective. Con-
tact your dealer.
