Precautions for the direct sunlight
-Set a sun-shade to protect the display from ultraviolet and infrared rays.
-The effect of the heat
(Even though the environmental temperature is fairly low, the temperature of the area under direct sunlight could be high.)
Monitor will break down or uniformity issue will occur.
-The effect of ultraviolet rays
LCD or color filter will deteriorate.
Please set this monitor to avoid the direct sunlight. These conditions may cause failure and/or deterioration.

-If the anti-dust solutions are not being considered ->
The dust will enter into the LCD panel through the gaps and will
cause the distorted image (see example below), and will break
down in the end.

Countermeasure against dust
-Create a completely sealed enclosure.
-The completely sealed enclosure shut off dust so it is
advantageous for installation in locations with excessive
amounts of dust, outdoor, and that may occur in salt.

air-breathe or exhaust the air.
Intake air fan:
The pressure in the enclosure is higher than out of enclosure.
Therefore, dust does not break in the housing. It is limited the size of
intake vent. And it is difficult to suck in much air(when using in dusty
area).

About dust
-Fundamentally, LCD monitor is designed for indoor usage.
-When it is being used outdoor, or at dusty places, such as
railway station or close to the traffic, the solutions against dust
must be considered.

-Regarding protecting the reflection non-glare, it is effective to

use the non-glare protection panel.
-Non glare coating has two methods. First method is AR coating
which decreases the reflection rate with light. Second method is
silica coating which decreases the reflection rate with scattered
reflected light.
-Silica coating is cheaper than AR coating. However, images
easily defocus and view angle is narrow with Silica coating.
Please check it before installation.

(Example : the place in front of the vents of radiators. When
the radiator is turn on in a cold winter morning, condensation
occurs.)

-the environment which has high possibility of water drops
“Semi-outdoor” place where strong winded-rain(typhoon)
could potentially reach the monitor. The place which is below
the pipes inside the ceiling. (When installing in these places,
countermeasures should be taken to avoid water drops to
reach the monitors. For example, covering the LCD monitor
with box. In such a case, consideration should be given for
direction of vent.)
