LCD screen
 The LCD screen is made of glass and may crack if subjected to
excessive force.
 Pixels that are not lit or are continuously lit may appear in certain
locations on the LCD screen. The appearance of such spots is a
normal occurrence associated with LCD screens and is not a sign
of a system malfunction. LCD screens are made using highly
precise technology. However, a very small number of dark pixels
or continuously lit pixels exist on each screen. Also, a distorted
image may remain on the screen for several seconds after the
system has been turned off.
 Direct exposure to sunlight may damage the system's LCD
screen. Be careful when using the system outdoors or near a
window.
 When using the system in a cold environment, you may notice
shadows on the graphics or the screen may appear darker than
usual. This is not a malfunction, and the screen will return to
normal when the temperature goes up.
 Do not leave still images displayed on the screen for an extended
period of time, as doing so may cause a faint image to be left
permanently on the screen.
