B Do not continue to use the projector in such cases, otherwise fire or electric shocks could result. B Check that no more smoke is coming out, and then contact an Authorised Service Center for repairs. B Do not attempt to repair the projector yourself, as this can be dangerous. Do not install this projector in a place which is not strong enough to take the full weight of the projector. B If the installation location is not strong enough, it may fall down or tip over, and severe injury or damage could result. Installation work (such as ceiling suspension) should only be carried out by a qualified technician. B If installation is not carried out correctly, there is the danger that injury or electric shocks may occur. If foreign objects or water get inside the projector, or if the projector is dropped or the cabinet is broken, turn off the power and disconnect the power cord from the wall outlet. B Continued use of the projector in this condition may result in fire or electric shocks. B Contact an Authorised Service Center for repairs. Do not overload the wall outlet. B If the power supply is overloaded (for example, by using too many adapters), overheating may occur and fire may result. Do not remove the cover or modify it in any way. B High voltages which can cause fire or electric shocks are present inside the projector. B For any inspection, adjustment and repair work, please contact an Authorised Service Center. Clean the power cord plug regularly to prevent it from becoming covered in dust. B If dust builds up on the power cord plug, the resulting humidity can damage the insulation, which could result in fire. Pull the power cord out from the wall outlet and wipe it with a dry cloth. B If not using the projector for an extended period of time, pull the power cord plug out from the wall outlet.

B Do not damage the power cord, make any modifications to it, place it near any hot objects, bend it excessively, twist it, pull it, place heavy objects on top of it or wrap it into a bundle. B If the power cord is used while damaged, electric shocks, short-circuits or fire may result. B Ask an Authorised Service Center to carry out any repairs to the power cord that might be necessary. Do not handle the power cord plug with wet hands. B Failure to observe this may result in electric shocks. Insert the power cord plug securely into the wall outlet. B If the plug is not inserted correctly, electric shocks or overheating could result. B Do not use plugs which are damaged or wall outlets which are coming loose from the wall. Do not place the projector on top of surfaces which are unstable. B If the projector is placed on top of a surface which is sloped or unstable, it may fall down or tip over, and injury or damage could result. Do not place the projector into water or let it become wet. B Failure to observe this may result in fire or electric shocks. Do not place liquid containers on top of the projector. B If water spills onto the projector or gets inside it, fire or electric shocks could result. B If any water gets inside the projector, contact an Authorised Service Center. Do not insert any foreign objects into the projector. B Do not insert any metal objects or flammable objects into the projector or drop them onto the projector, as doing so can result in fire or electric shocks. After removing the battery from the remote control unit, keep the battery out of the reach of small children and infants. B The battery can cause death by suffocation if swallowed. B If the battery is swallowed, seek medical advice straight away. Do not allow the + and - terminals of the batteries to come into contact with metallic objects such as necklaces or hairpins. B Failure to observe this may cause the batteries to leak, overheat, explode or catch fire. B Store the batteries in a plastic bag and keep them away from metallic objects. During a thunderstorm, do not touch the projector or the cable. B Electric shocks can result. Do not use the projector in a bath or shower. B Fire or electric shocks can result. Do not look into the lens while the projector is being used. B Strong light is emitted from the projector's lens. If you look directly into this light, it can hurt and damage your eyes. B Be especially careful not to let young children look into the lens. In addition, turn off the power when you are away from the projector. Do not bring your hands or other objects close to the air outlet port. B Heated air comes out of the air outlet port. Do not bring your hands or face, or objects which cannot withstand heat close to this port, otherwise burns or damage could result. Replacement of the lamp unit should only be carried out by a qualified technician. B The lamp unit has high internal pressure. If improperly handled, explosion might result. B The lamp unit can easily become damaged if struck against hard objects or dropped, and injury or malfunctions may result. When replacing the lamp, allow it to cool for at least one hour before handling it. B The lamp cover gets very hot, and contact with it can cause burns. Before replacing the lamp, be sure to unplug the power cord from the power outlet. B Electric shocks or explosions can result if this is not done. Caution Do not cover the air inlet or the air outlet. B Doing so may cause the projector to overheat, which can cause fire or damage to the projector. B Do not place the projector in narrow, badly ventilated places such as closets or bookshelves. B Do not place the projector on cloth or papers, as these materials could be drawn into the air inlet port. Do not set up the projector in humid or dusty places or in places where the projector may come into contact with smoke or steam. B Using the projector under such conditions may result in fire or electric shocks. When disconnecting the power cord, hold the plug, not the cord. B If the power cord itself is pulled, the cord will become damaged, and fire, short-circuits or serious electric shocks may result. Always disconnect all cables before moving the projector. B Moving the projector with cables still attached can damage the cables, which could cause fire or electric shocks to occur. Do not place any heavy objects on top of the projector. B Failure to observe this ma ...
