[. . . ] $ A triangle indicates a situation against which you need to exercise caution. The example shown here indicates you should take precaution against electric shock. A circle with a line through it indicates information about an action that you should not perform. The specific action is indicated by the figure inside the circle. [. . . ] Disassembling or modifying the 3D glasses can void their warranty or make them ineligible for servicing. Request all servicing and repair from your original retailer or the contact specified for repair. Do not drop the 3D glasses, and do not allow them to be stepped upon, subjected to strong force, or impacted by an object dropped from above. Doing so can break the lenses or other parts and create the risk of personal injury. Do not drop the 3D glasses or otherwise subject them to impact. E-2 - Do not dispose of the 3D glasses by burning them. Never try to dispose of the 3D glasses by burning them. Doing so can cause an explosion, which creates the risk of fire and personal injury. Do not use or leave the 3D glasses in any of the following locations. Doing so creates the risk of fire and electric shock. · Areas subject to large amounts of moisture or dust · In a kitchen or other areas exposed to oil smoke · Near a heater, on a heated carpet, or in an area exposed to direct sunlight · Other areas subjected to temperature extremes Never leave the 3D glasses in a bathroom or anywhere else there is the chance that they will become wet. Keep the battery and other accessory items of the 3D glasses out of the reach of small children. Inhaling or swallowing small items create the risk of suffocation, indigestion, etc. Should a button battery or accessory ever be swallowed, contact a physician immediately. E-3 - Button battery Misuse of a battery can cause it to leak and stain the area around it, or to explode, creating the risk of fire and personal injury. Make sure that you always observe the following precautions. · Never try to take the batteries apart and do not allow them to become shorted. · Never expose the batteries to heat or throw them into fire. Leaking batteries create the risk of malfunction and damage. Never try to bend the frame or otherwise apply undue force. A scratched or broken lens can cause deterioration of 3D image quality. · Do not subject the lens to strong force. · Do not scratch the lens surface with a sharp object. · Never drop or bend the 3D glasses. Do not allow the synchronization sensor of the 3D glasses to become dirty, and do not cover it by affixing a label, sticker, etc. A blocked sensor can make synchronization impossible and interfere with proper operation of the 3D glasses. E-7 When viewing images in a room illuminated by fluorescent lighting, the frequency of the lighting can cause flickering of overall light in the room. If this causes problems, dim the fluorescent lighting, change to a different type of lighting, etc. (Projection in a totally darkened room is not recommended, especially when small children are present. ) Be sure to wear the 3D glasses correctly. The 3D image will not appear normal if the glasses are worn upside down or backwards. [. . . ] Level of illumination in the area Projected image size Distance from the viewer to the screen 3D image content and quality Under certain conditions, an image may not appear three-dimensionality at all. If this happens, try darkening the room and move closer to the screen. This can improve the 3D appearance of the image. E-13 L/R Swapping If you feel that the dimensionality of the 3D image appears backwards while viewing with the 3D glasses, it probably means that the shutter operations of the image and the glasses are reversed. When this happens, either press the projector's [ENTER] key or press the on button of the 3D glasses to swap the left and right images with each other (L/R swapping). [. . . ]
