Page 4: Fuse For Circuit Protection
This projector is equipped with the following protec- tions to operate in safety. ❏ Fuse for circuit protection The fuse is located in the rear inside a projector. (Refer to figure.) When either the LAMP indicator or the READY indicator is not illuminated, fuse may be opened. Check the fuse as following steps.
Page 5: Overheat Protection
❏ Overheat Protection The temperature monitor system -- The temperature monitor system is provided to prevents damage of optical components (the LCD panel and polarization film etc.) inside a projector from overheat. Two protection systems are provided. Each system operation as follows ; ----- The temperature monitor -2 : ----- ----- The temperature monitor -1: ----- I Temperature check of lamps.
Page 6 This Projector is equipped with 2 Projection Lamps to ensure brighter image and those lamps are controlled by Lamp Management Function. Lamp Management Function detects status of two lamps and shows status on screen or on LAMP REPLACE indicator. This function also automatically controls Lamp Mode when any of lamps is out for end of life or malfunctions.
