protective function does not allow your projector to be turned on. Wait some time and then turn it
on.
Are you using the projector at high elevations with an altitude of approximately 5500 feet/1600 meters
or higher? The cooling fan settings need to be configured when using the projector at high elevations.
Please contact your dealer/distributor for instructions.

See if the lens and other parts have condensation on them. If the projector is turned on in a
warm place after storage in a cold place, the lens and other optical components inside may develop
condensation. In such a case, please wait several minutes until the condensation disappears.
