Safety Protections This projector provides the following safety 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. 1. Fuse The fuse is located inside of the projector. When both of FUSE PART NO.
Safety Protections 3. Mechanical switches There are some mechanical switches inside of the projector to detect that the covers, filters or lamps are mounted correctly. When one of following switches detects an error (open), the projector cannot turn on. This projector provides 4 mechanical switches and 4 lamp selection switches as follows; - Lamp1 cover switch (SW902) - Lamp2 cover switch (SW905) - Bottom cover switch (SW904)
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.
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.
Lamp Replacement When the life of the projection lamp of this projector draws Top Control to an end, the LAMP1/2 REPLACE indicator lights yellow. If this indicator lights yellow, replace the lamp with a new one promptly. CAUTION For continued safety, replace with a lamp of the same type.
How to Reset the Lamp or Filter Timer How to reset the Lamp Time Special Menu (Lamp) Press the MENU button to display On-Screen Menu.
