One flash

Temperature, 
abnormality

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.

Two flashes

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

be defective. Contact your dealer.

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.
