2.3 Precautions for dust
Please don’t set up vent, when installing the monitor on to the pole and the wall. The
dust causes the above situation by intrusion of dust to inside of the product.
About dust
- This product is for use indoors.
- -When it is used at outdoor, or at dusty places, such as railway station or close to
the traffic, the measures against dust must be considered.
Please observe the following instructions when installing.
The effect of dust
-If the anti-dust measure against dust is not 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.
The dust enters into the LCD panel
and causes the distorted image.
Countermeasure against dust
-Create a completely sealed enclosure.
-The completely sealed enclosure can shut off dust so it is advantageous for
installation in locations under the effect of excessive amounts of dust, outdoor, and a
salt damage.
-You will need the countermeasuresagainst thermal at the same time, such as using
the heat exchanger or the air conditioner etc.
Regular maintenance of the enclosure is required to maintain performance.
Precautions for using anti-dust enclosure
-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.
(2)it may raise the internal temperature for a monitor when using the filter, because of raising
the air resistance.
Please reduce the air resistance by increasing the area of filter, etc.
(3)when circulating air with a fan, it needs attention how to make the enclosure whether
exhaling or inhaling air from the fan.
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).
Exhaust air fan:
The pressure in the housing is lower than out of enclosure. Therefore, dust breaks in the
housing. It has much size of intake vent. And it is easy to control the temperature(when using
in less dusty area and severe temperature requirements).
※to keep the performance, please clean the filter regularly

2.4 Reflected glare
Reflected Glare
•With a protection panel, reflected glare may occur and may degrade visibility.
•Anti glare screen protector is effective to prevent reflected glare.
•There are two methods of anti glare.
1. AR coating which reduces reflection and eliminates stray light.
2. Silica coating (AG coating) which reduces reflection with scattered reflected light. AG coating is lower price than AR coating. However, images easily
defocus and view angle is narrow with AG coating. Please select the right protection panel for your purposes .
Panel surface treatment：Anti-glare treatment ( Haze Value 1%)
•Generally, when decreasing glare, image quality comes down. Therefore, please select the suitable protection panel
in each installing site.
•The closer a distance from the protection panel to the LCD panel get more clear image. However, LCD surface
temperature rises.
•Please make sure that the LCD surface temperature is below 140°F(60℃)by keeping a space (at least 3cm) between
monitor and protection panel a monitor and a wall to flow the air. The space size may differ depending
on installation condition and ambient air temperature. If air flow fan is required, sufficient test is needed.

•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 environment which has high possibility of condensation
•Place where temperature is generally low but has frequent warm air flow.
(For 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, do not install in a place where the wind is blowing.)

2.6 Precautions for Vibration/Expansion/Afterimage
This monitor is not designed to set in any places with strong vibrations, such as in
motor vehicles.
If the monitor will be used in the place with possibility of even small vibration,
such as at railway station’s platform, should take some measures such as using a
shock absorber .
Vibration
・Image burn-in will not occur in LCD display.
However, when a still image is being displayed for a long period, afterimage
might occur.
For an temporary afterimage can be removed by displaying Black or white
screen. It can be removed by playing videos or turning off the monitor. The
longer the same screen is displayed, the harder to remove afterimage. Change
the image occasionally.
Afterimage
When using acrylic or polycarbonate protection panel, be aware of expansion due
to heat or moisture absorption.
Acrylic protection panel can expand about 0.4%
(approx. 6.2 mm for 70”)
Install the protection panel with a space so that it won’t be distorted due to
expansion.
Expansion ・The following measures are expected to prevent afterimage.
-Display video as long as possible. (e.g. Display 10 seconds’ video after 5
minutes’ still image)
- Prevent increase of the contrast difference between background and content.
Change the color occasionally.
Shadow
When the background is gray and text and shapes are white color, depending on
the angle of view of the screen, you may see uneven colors or brightness
horizontally or vertically.
If it is displayed in a short time, it can recover by turning off power.
However if it is displayed for a long period, you need to change the image regularly,
or it takes time to recover.
Temporally display unevenness
After repair
Temporary display unevenness may occur when pressure is added to the
product during transportation and installation.
It is not defective but it is a display unevenness which can be repaired.
The following works may solve the problem.
-Wipe the surface of entire LCD carefully.
-Tap lightly something like wiping off the spot of unevenness.

2.7 Precautions for power supply
-This monitor are designed to be used under commercial 100V-240V power supply, but shortage
of power supply may occur in wall video installation.
-Arrange plural circuit and level power consumption in each circuit.
-Prepare a spare ground wiring for maintenance to attach an earth strap.
-Check the neutral rating of the power strip and make sure that the total current consumption of
the connected equipment does not exceed the current value of the power strip.
- It is not recommended to use a power strip of a movable blade plug that moves the plug blade.
Prepare a spare ground wiring for maintenance to attach an earth strap. If an excessive load
is applied to the plug blade, abnormal heating may occur, even if the current is below the
rated current. Please use un-movable blade plug as much as possible.
- If the cord is pulled with an excessive force, the internal core wire may be damaged and
abnormal heat may occur, therefore it is recommended that the cord is fixed with a bushing or
the like.

2.9 Precautions for space between monitors(Multi-display etc.)
About thermal influence
-In particular, when monitors are installed one above the other, the temperature
raise of topside monitor cause of the exhaust heat from downside monitor.
Regarding the countermeasure against temperature, please keep the clearance
in P.9.
In fact, when installing multi-display, it is hard to keep the clearance in P.9.
Therefore, please keep the temperature requirements to do the
countermeasures as below.
1) Reduce the surrounding temperature(using an air-conditioner)
2)Get down the brightness(when a brightness gets down, a power consumption
and heat gets down)
3)Keep much clearance between the monitors
4)Flow the air forcibly between monitors
It is effective to use the spot cooler or fan in the back(when the monitors are
hit by the wind, they are easily attached the dust).
About expansion
The cabinet and frame of the LCD monitor is expanded due to heat.
It is necessary to secure enough space when aligning multiple monitors.
If the space between monitors is small, the weight is loaded to LCD panel by
heat expansion.
It is necessary to have the gap when installing large monitor. (It is about 5 mm
usually.)
Hiding the gap between the bezels
Black tape
Please be careful not to block it as
much as possible so as to pass
through.
If the gap between monitors spoils appearance (e. g. back of the monitor can
been seen through), please hide it by affixing black tape at the rear.
Note: DO NOT seal the “exhalation fan and intake-nozzle” by black tape.
Please attach the tape in front of connecting cables.
It is necessary to check the tape periodically to make sure that the tape isn’t
detached from the monitor as time goes by.
