Enjoying 3D Image Viewing (Continued) Precautions on viewing 3D images ■ When viewing 3D images continuously, be sure to take a break periodically to prevent eye strain. ■ Take regular breaks, at least 5 to 15 minutes after every 30 to 60 minutes of 3D viewing. * Based on the guidelines issued by the 3D Consortium revised December 10, 2008. ■ View 3D images at the appropriate distance from the screen. The recommended distance is three times the effective height of the picture. Examples of recommended distances 100-inch 16:9 picture: Approx. 12.3 ft (3.8 m) Viewing should not be done closer than the recommended distance. Refer to page 21 for details on the diagonal size and height of the picture. ■ Maintain an appropriate distance from the screen. Viewing from too close a distance can strain your eyes. If you experience eye strain, immediately discontinue viewing. If you experience any of the following symptoms during viewing: - nausea - queasiness/dizziness - headache - blurry vision or double vision that lasts longer than few seconds Do not engage in any potentially hazardous activity (for example, driving a vehicle) until your symptoms have completely gone away. If symptoms persist, discontinue use and do not resume 3D viewing without discussing your symptoms with a physician. ■ Be careful of your surroundings when viewing 3D images. When you view 3D images, objects may appear at a distance closer or farther than the actual screen. This may cause you to misjudge the distance to the screen and possibly result in injury if you accidentally hit the screen or surrounding objects. As you get more comfortable viewing 3D images: ■ Operate the "3D Depth Adjust" function to adjust the 3D effect. (See page 70.) ■ Adjust the projected image to the most comfortable viewing size by zooming. (Projecting images on the smallest or largest screen size possible may eliminate the 3D effect and strain your eyes.) ■ Use the Invert function to properly set the video for your left and right eyes. (For details on using "Invert", see page 70.) ■ A picture simultaneously projected from more than two projectors may not appear 3D. Info • The projected image may become dark when using the 3D projection function (with "3D" set to "On"). • When "3D" is set to "On", the following functions may not work fully or may not be available at all. - GEOMETRIC ADJUSTMENT/H&V KEYSTONE/ SPHERE - V-Image Shift - CBNR • If the power of your left and right eyes greatly differs and you primarily use one eye for viewing the images, the images will not appear in 3D. In addition, images may be difficult to view in 3D or images may not be able to be viewed in 3D depending on the individual or the content being displayed. The 3D effect varies with the individual. 62
