[. . . ] A black circle indicates information about an action that you must perform. The example shown here indicates you must unplug the power cord from the power outlet. E-1 * Warning + ! [. . . ] · Use only the type of batteries that is specified for use with the 3D glasses. Never look directly at the sun while wearing the 3D glasses. E-4 * Caution Remove batteries from the 3D glasses immediately after they go dead. Remove batteries from the 3D glasses if you do not plan to use them for a long time. Be sure to follow all applicable local laws and regulations when disposing of batteries. Be sure to follow all applicable local laws and regulations when disposing of the 3D glasses. Do not view 3D images if you are experiencing any of the symptoms described below. · Should the 3D image ever start appearing double or lose its three-dimensionality, stop watching. Continued watching can cause eye fatigue. + You need to wear your glasses or any other devices you normally use for vision correction. If you normally wear glasses or contact lenses, you should be wearing them when you watch 3D images with the 3D glasses. When 3D images are being watched by a small child, a competent adult should be on hand to monitor the child, to ensure that the 3D images are suitable for the child, that the child does not watch the 3D images for too long an uninterrupted period, etc. Do not wear the 3D glasses except when viewing 3D images. Using the 3D glasses for any other purpose besides viewing 3D images creates the risk of personal injury and eye fatigue. E-5 Do not wear the 3D glasses for long periods. Should you experience any reddening, soreness, or irritation of your nose or temples, take off the 3D glasses. These symptoms can be caused by pressure generated by long-term wear of the 3D glasses, and create the risk of deteriorated physical health. - Use these glasses only for the purpose for which they are intended. The 3D glasses are not designed or intended for use as vision correction glasses, sunglasses, or eye protection goggles. Incorrect use creates the risk of personal injury. E-6 Operating Precautions Never use or store the 3D glasses in the following locations. Doing so creates the risk of malfunction of and damage to the 3D glasses. · Locations subjected to electrostatic charge · Locations subjected to temperature extremes · Locations subjected to extreme moisture · Locations subjected to sudden temperature changes · Locations subjected to large amounts of dust · Locations where there is the danger of getting wet Do not use the 3D glasses in environments subjected to temperature extremes. The 3D glasses are designed for use within the temperatures of 5ºC to 35ºC (41ºF to 95ºF). 3D image quality and product reliability are not guaranteed when the 3D glasses are used outside of this temperature range. A scratched or broken lens can cause deterioration of 3D image quality. [. . . ] 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). [. . . ]
