User Operation Guide WARNING Assembling without the correct use of bolts and screws at designated points may result in injury and damage to properties or the unit collapsing from its installed position. Should a malfuction occur disconnect the power from the main socket and surround the area with ropes to prevent others from getting near it. Check and ensure the ceiling where you install can support the weight or the projector and ceiling mounting. All Ceiling Mounting Brackets are to be firmly secured so the unit will not drop off its installed position. Steps should be taken to ensure the ceiling and installed unit can withstand external forces like earthquakes, vibrations, etc. Do not remove any bolts and screws from the Ceiling Mounting Brackets or do any changes to the Ceiling Mounting Brackets. Do not install near an air-conditioner. Do not install at place where there are excessive dust and smoke as fire could arise from these sources. 4
