Precautions when using the Touch Screen

1.  When using the touch screen, be careful not to tear the surface with any sharp 

objects.

2.  To ensure normal use of the touch screen, ensure that both the screen  surface 

and your fingers are clean and dry.

3.  To ensure precise positioning on the touch screen, avoid handling or touching 

the glass frame when you are touching the screen.

4.  Turn the computer off for safety before cleaning the screen and frame with a 

soft cotton cloth. Do not wipe it with a wet cloth as this may leave a water mark 
and affect touch operation.

5.  Do not place or drop anything which could obstruct it in the four corners of 

the screen or any part of its frame, because this could separate the screen 
from the frame and stop the screen from being able to sense position properly. 
Please avoid leaving water and dust in the gap between the casing and glass 
when you are cleaning the frame.

6.  Avoid using the touch screen in dusty environments or hot or humid conditions. 

Any abrupt temperature change may cause condensation on the inside surface 
of the glass screen, which will disappear after a short time and does not affect 
normal use.

7.  Do not spray any liquid or cleaner directly onto the touch screen.
8.  Do not use a solvent or industrial alcohol-based cleaners.
