The slots and openings in the display are provided for necessary ventilation.
To ensure reliable operation of the display and to protect it from overheating,
these slots and openings must never be blocked or covered.
Unless proper ventilation is provided, the display may gather dust and get
dirty. For proper ventilation, observe the following:
Do not install the display face up, down or sideways.
Do not install the display turned over or upside down.
Never cover the slots and openings with a cloth or other materials.
Never block the slots and openings by placing the display on a bed,
sofa, rug or other similar surface.
Never place the display in a confined space, such as a bookcase or
built-in cabinet, unless proper ventilation is provided.
Leave some space around the display set as shown below. Otherwise, air-
circulation may be inadequate and will cause overheating, which may cause a
fire or damage to the display set.
