Issues 3D The 3D Active Glasses are not working correctly The screen seems to flicker slightly when you watch 3D images. ◀ The 3D images don't look quite right. The batteries in the 3D glasses don't last Solutions and Explanations •• Make sure the glasses are turned on. •• The 3D Active Glasses may not work properly if there is any other 3D product or electronic devices turned on near the glasses or TV. •• If there is a problem, keep other electronic devices as far away as possible from the 3D Active Glasses. •• You may notice a small amount of screen flickering when watching 3D images under a fluorescent lamp (50Hz ~ 60Hz), a 3 wavelength lamp, or a strobe light. If this occurs, dim the light or turn it off entirely. •• The ideal viewing distance is three times or more the height of the ▶ screen. •• We also recommend sitting with viewer's eyes on a level with the screen •• Turn off 3D glasses while not using them. If you leave 3D glasses on, battery lifespan is shortened English
