2.6 Vibration/Afterglow/Expansion precautions Confidential For use by Sharp authorized dealers and distributors only. Not for general distribution. Vibration Afterglow This monitor is not designed to set in any places with strong vibrations, such as in motor vehicles. If the monitor will be used in the place with possibility of even small vibration, such as at railway station's platform, take some measures such as using a shock absorber . ・ When a still image is being displayed for a long period, afterglow might occur. It can be removed by playing videos or turning off the monitor. The longer period of time a still image is being displayed, the harder it is to remove afterglow. Change the image occasionally. Expansion When using acrylic or polycarbonate protection panel, be aware of expansion due to heat or moisture absorption. Acrylic protection panel can expand about 0.4% (approx. 6.2 mm : 70") Install the protection panel with a space so that it won't be distorted due to expansion. ・The followings are expected to prevent afterglow. - Display video as long as possible. (e.g. Display 10 seconds' video after 5 minutes' still image) - Prevent increase of the contrast difference between background and content. Change the color occasionally.
