Precautions for direct sunlight

Please set this monitor to avoid the direct sunlight. These conditions may cause failure and/or deterioration.

Precautions for dust

-Fundamentally, LCD monitor is designed for indoor usage.

When it is being used outdoor or at dusty places such as

-when using the anti-dust display(enclosure), please remove 

the

-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.

(1)it is possible to prolong the filter life by 
using two filter and exchanging the fine 

dust with filter.

-If the anti-dust solutions are not being considered ->

The dust will enter into the LCD panel through the gaps and will

(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.

screen pre-filter.

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.

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

Intake air fan:

The pressure in the enclosure is higher than out of enclosure

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 dust enters into the LCD panel 

and causes the distorted  image.

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).

-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.

to keep the performance, please clean the filter regularly

Precautions for reflection, dew condensation and water drops

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

-Humidity condition for IDP

Range of humidity condition for IDP : From 20% to 80%(no

-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

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

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 install LCD away from condensation and liquid drops.

-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

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.

(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)

-the closer a distance from the protection panel to the LCD panel  
get the clear image. Indeed, LCD surface temperature raise.

(Please keep 3 cm clearance to flow the air.)

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.)

Precautions for vibration, inclination, voltage, residual images and expansion

-This information display is not designed for the usage in any 
places which have strong vibrations, such as inside motor 

-When a still image is being displayed for a long period, image 
retention might occur.

vehicles.

-If the monitors will be used in the place which has the possibility 
of even small vibration like railway station’s platform, shock 
absorber must be considered.

g

-Image retention can be removed by displaying motion images 
or turning off the monitor. However, the longer the still image is 
being displayed, the harder to remove the  image retention, 
therefore, the solutions mentioned above should be taken 

periodically.

-Installing with inclination more than 20 degrees is impossible.

-When using acrylic or polycarbonate protection panel, please be 
aware of expansion due to heat or moisture absorption.

Please use certainly the attached or designated power cord

Acrylic protection panel can expand about 0.4%(about 8 mm) 
when absorbing the moisture.

Please fix the protection panel not to strain it by expansion.

-Please use certainly the attached or designated power cord.
Attached power cord is three pin for 100V level. For 
200V(50/60Hz) level, provided service parts(QACCJA104WJPZ)
