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. 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.

Note: The touch screen will not affect other computer processes when

used normally.

6. Recognition of touch gestures can be influenced by the following:

•

Touching the correct place on the screen.

•

The speed of movement.

•

The time interval from when the screen was last touched.

Note: The user can consult this manual and also the related Windows help

content to learn accurate hand gestures.
