  • Page 61: Important Safety Instructions

    ® • As an “ENERGY STAR ” partner, JVC has determined that this product or product model meets the ® “ENERGY STAR ” guidelines for energy efficiency. IMPORTANT SAFETY INSTRUCTIONS 1) Read these instructions. 2) Keep these instructions. 3) Heed all warnings.
  • Page 62 16) Avoid improper installation and never position the unit where good ventilation is impossible. When installing this TV, distance recommendations must be maintained between the set and the wall, as well as inside a tightly enclosed area or piece of furniture.
  • Page 63 WARNING Burn-in A characteristic of Plasma Display Panels (PDPs) is that displaying the same image for a long time causes a part of the image to stay on the screen (this is called phosphor burn-in). Avoid burn-in as follows. IMAGE SHIFT The picture displayed on the screen is shifted up, down and to the left and right at regular intervals.
  • Page 64 WARNING If Burn-in has occurred If burn-in occurs, try the BURN-IN IMAGE REDUCER function (page 48). If burn-in is minimal it may gradually become less noticeable. Note: Once burn-in occurs it will never disappear completely. Point defects PDPs use collections of fine pixels to display images. While there is no problem with more than 99.99% of these pixels, please understand that a very small number of pixels may not light or may light all the time.
