•The LCD screen is manufactured to precise specifications. Although over 99.99% of the pixels function normally,
0.01% of the pixels are either missing or constantly lit (red, blue or green). This is normal and not a cause for
concern.
 The liquid crystal protection panel is a specially manufactured component. Wiping it with a hard cloth, or rubbing
it vigorously will scratch the surface.
 If a still image is displayed for an extended period of time, it may generate a temporary afterimage (phosphor
burn-in). (However, such images can be removed by displaying normal video for a while.)
 The response speed and brightness of liquid crystal vary with ambient temperatures.
 Let authorized service person handle installation.
Be sure to consult with the service person about the installation. Make sure that the wall is strong enough to
endure the weight of this unit including the mount fittings. If not strong enough, it may fall off resulting in injury.
 Do not install the unit in a place exposed to direct sunlight, as it may damage the cabinet and the LCD screen.
 Do not install the unit in locations where enough space cannot be provided around it as heat may build up inside
preventing normal operation. Be sure to provide enough space around the unit.
 Exposing the LCD screen to intense light sources will impair its characteristics and lower image quality. 
 In an environment exposed to drastic temperature fluctuations, condensation may build up on and inside the
LCD screen. This may lower the quality of the screen and may damage it.
 Some video images may appear blurred on the screen.
 Leaving the unit in a location exposed to high temperature and humidity for an extended period of time may
damage the LCD screen and cause blurring.
