Protections This projector is equipped with the following protections 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.
❏ 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 -1: ----- ----- The temperature monitor -2 : ----- I Temperature check of lamps.
LAMP REPLACEMENT Before Replacement 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.
