Precautions for the direct sunlight
Countermeasure
The effect of 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.

Please don’t set up vent, when installing the display on to
the pole and the wall. The dust causes the above phenomenon
by intrusion of dust to inside of the product.

Precautions for dust
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.

must be considered.
The effect of dust
-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.

down in the end.
The dust enters into the LCD panel
and causes the distorted image.
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.

Precautions for using anti-dust display
-When using the anti-dust display(enclosure), please remove
the dust with filter.

Precautions for using the filter
(1)it is possible to prolong the filter life by
using two filter and exchanging the fine
screen pre-filter.
using two filter and exchanging the fine
screen pre-filter.
(2)it may raise the internal temperature for a display when using the
filter, because of raising the air resistance.
Please reduce the air resistance by increasing the area of filter, etc.

(3)when making the enclosure, it needs the caution whether the fan
air-breathe or exhaust the air.
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).

Precautions for reflection
About reflection
-when attaching LCD panel to protection panel, the reflection occurs and the visibility comes down.
-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.

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.
-Generally, when decreasing the reflection rate, image quality comes down. Therefore, please select
the suitable protection panel in each installing location.

-This model is only for internal use. Please avoid weather and direct sunlight when installing. They cause breakdown and degradation.
-Humidity condition for IDP
Range of humidity condition for IDP :
From 20% to 80%(no condensation)
-Dew condensation and/or liquid drops will cause the breakdown of the circuit and/or LCD panel.
Please install LCD away from condensation and liquid drops.
-About dew condensation
The back cabinet of the product is plate. So dew condensation occurs easily.
-the environment which has high possibility of condensation
The place where temperature is generally low but has frequent warm air flow.
(Example : the place in front of the vents of radiators. When the radiator is turn on in a cold winter morning, condensation occurs.)
Near the sea, lake, mountain and so on where humidity is high
-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.)
covering the LCD monitor with box. In such a case, consideration should be given for direction of vent.)
-caution for the wind of the typhoon
Please install so that you can remove the influence from the wind.
-caution for salt damage
Please hold counsel with us in advance when installing near the sea where salt damage may occur.
-caution for sulfide
Please don’t install near the hot spring and volcano where there may occur the influence from sulfide.
-caution for organic gas and flammable gas
Please don’t install the place where there may be organic gas and flammable gas.
