Important Safeguards These safety instructions are to ensure the long life of your projector and to prevent fire and shock. Please read them carefully and heed all warnings. Installation 1. For best results, use your projector in a darkened room. 2. Place the projector on a flat, level surface in a dry area away from dust and moisture. 3. Do not place your projector in direct sunlight, near heaters or heat radiating appliances. 4. Exposure to direct sunlight, smoke or steam can harm internal components. 5. Handle your projector carefully. Dropping or jarring can damage internal components. 6. Do not place heavy objects on top of the projector. ii Important Information Fire and Shock Precautions 1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 12 inches (30 cm) of space between your projector and a wall. 2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified NEC service personnel. 3. Do not place any liquids on top of your projector. 4. Do not look into the lens while the projector is on. Serious damage to your eyes could result. 5. Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can cause unpredictable outcome such as fire or injury to the eyes. 6. Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to melting of the cap and possibly burning your hands due to the heat emitted from the light output. 7. The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply fits this requirement before attempting to use your projector. 8. Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire. 9. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet. 10. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire. 11. Do not handle the power plug with wet hands. iii Table of Contents Table of Contents ....................................................................................... 1 Usage Notice .............................................................................................. 2 Precautions ......................................................................................................... 2 Introduction ............................................................................................... 4 Product Features ................................................................................................. 4 What's in the Box? ............................................................................................... 5 Package Overview ............................................................................................... 6 Main Unit ......................................................................................................................... 6 Control Panel .................................................................................................................. 7 Connection Ports ............................................................................................................ 8 Remote Control ............................................................................................................... 9 Installation ................................................................................................ 10 Connecting the Projector ................................................................................... 10 Powering On/Off the Projector ............................................................................. 11 Powering On the Projector ............................................................................................ 11 Powering Off the projector ............................................................................................ 12 Warning Indicator ......................................................................................................... 12 Adjusting the Projected Image ........................................................................... 13 Adjusting the Projector Image Height ........................................................................... 13 Adjusting the Projector Zoom / Focus .......................................................................... 14 Adjusting Projected Image Size ................................................................................... 14 User Controls .......................................................................................... 15 Control Panel & Remote Control ........................................................................ 15 On-Screen Menus ............................................................................................. 17 How to operate .............................................................................................................. 17 Language ...................................................................................................................... 18 Image All ...................................................................................................................... 19 Image Computer ........................................................................................................... 21 Image Video ................................................................................................................. 22 Setup ............................................................................................................................ 23 Appendices ............................................................................................... 25 Troubleshooting .................................................................................................
