Page 7: Temp. And Airﬂow Sensors
Safety Protections 4. Temp. and airﬂow sensors The projector provides 2 temperature sensor ICs and an airﬂow sensor. The temperature sensor ICs monitor internal temperature and external temperature (around the intake duct ) respectively. The airﬂow sensor monitors intake air- ﬂow through the airﬁlter to detect the airﬁlter clogged.
Page 8: Air Filter Replacement
Air Filter Replacement Air ﬁlters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air ﬁlters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector.
