Wait for about 5 minutes without operating the projector. After 5 minutes have elapsed, unplug the power cord and then plug it back in again. If the projector overheats, check the following two points. Check that the air inlet and air outlet are clear, and that the projector is not positioned against a wall. If the air filter is dirty, it should be cleaned. When the power cord is plugged back in, the projector will return to its previous state, so press the [Power] button on either the projectors control panel or the remote control to turn it back on. If the projector continues to overheat even after the above points have been checked, or if the indicators show a problem when the power is turned back on, stop using the projector, disconnect the power cord from the electrical outlet, and contact your dealer or the nearest address provided at “International Warranty Conditions” in Safety Instructions/ World-Wide Warranty Terms. 15 75 Problem with lampDisconnect the power cord from the electrical outlet and then remove the lamp and check if it is broken.
