Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projec- tor, it will automatically turn off by operating one of the following protection circuits. Thermal switch There is the thermal switch (SW902) inside of the projector to detect the internal temperature rising abnormally.
Circuit Protections Warning temperature and power failure protection The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or the cooling fans stop spinning, or the power supplies in the projector are failed. - If the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector.
Lamp Replacement Lamp replacement WARNING: - For continued safety, replace with a lamp assembly of the same type. - Allow the projector to cool for at least 45 minutes before you open the Screw Lamp Cover lamp cover. The inside of the projector can become very hot. - Do not drop the lamp module or touch the glass bulb! The glass can shatter and cause injury.
