Fastening the screws too tightly might bend the display module too much and break it. The
screws must also be fastened gradually: first fasten all screws slightly, then more tightly.
NOTE: When reassembling the LCD Display component, be careful that no dirt or finger prints
are left between the LCD element and the protection glass window.
NOTE: If the LCD Display unit is broken, handle it carefully to avoid injury (the LCD Display
component and the backlight lamp(s) are made of glass). Wash your hands if you touched
liquid crystal, which may flow out from a broken LCD Display component.
NOTE: Do not touch, push or rub the exposed display module surface. Keep the surface clean.
