Operating this display in confined spaces is not recommended.
• If the display is to be used in confined spaces, observe the following conditions,
shown in the drawing above:
A ≥ 150 mm
B ≥ 250 mm
C ≥ 30 mm
• Keep the temperature in the closed space "Y" and the open space "X" at 40°C
or less. In particular, the space "Y" should be ventilated sufficiently by the air
conditioner or fan so that hot air is not trapped in the space. Thus, everywhere
in "Y" must be kept at 40 °C or less. If hot air remains in the closed space, the
temperature may rise, causing a malfunction or fire. As a precaution in case of
accidents, the inner wall should have sufficient heat resistance or fire resistance.
Direct air from the air conditioner in the direction of the arrow (from where no fan is
installed to where a fan is provided).
