Connect all the cables securely. When connecting or
disconnecting the cables, be careful not to apply stress to the
cables. (It may cause disconnection.)
Ground the human body to prevent against troubles and dust
adhesion to the LCD by static electricity. When assembling the
LCD, use a discharge blower to prevent against dust intrusion.
Be careful to the high voltage of the invertor PWB transformer.
Install the ferrite core onto the specified position of the cable
securely.

Note for handling of Touch panel
The transparency of the touch panel should be vitally important.
Do not put finger prints or water print on the surface. Use clean
finger such or gloves and masks.
For handling, do not hold the transparent area, and do not hold the
heat seal connector section to assure reliability. 
Do not overlay touch panels. The edge may damage the surface. 
Do not put a heavy thing on the touch panel.
Do not apply a strong shock, and do not drop it. 
When attaching the protection film again, carefully check for no
dirt. If there is any dirt, it is transferred. 
To clean dirt on the surface, use dry, soft cloth or a cloth immersed
in ethyl alcohol.
Check that the housing does not give stress to the touch panel. 
Be careful not to touch the touch panel with tools. 
The heat seal section is easily disconnected. Be careful not to give
a stress to the heat seal section when installing. 
The touch panel is provided with an air groove to make the exter-
nal and the internal air pressure equal to each other. If water or oil
is put around the air groove, it may penetrate inside. Be careful to
keep the air groove away from water and oil. 
Input is performed with fingers. Do not use a hard thing for input-
ting. 
Note for handling of LCD
The LCD elements are made of glass. BE careful not to give them
strong mechanical shock, or they may be broken. Use extreme
care not to break them.
If the LCD element is broken and the liquid is leaked, do not lick it.
If the liquid is attached to your skin or cloth, immediately clean with
soap. 
Use the unit under the rated conditions to prevent against damage.
Be careful not to drop water or other liquid on the display surface.
The reflection plate and the polarizing plate are easily scratched.
BE careful not to touch them with a hard thing such as glass,
tweezers. Never hit, push, or rub the surface with hard things.
When installing the unit, be careful not to apply stress to the LCD
module. If an excessive stress is applied, abnormal display or
uneven color may result.
