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 on the four corners or frame of the screen. This could

separate the screen from the frame and prevent the screen sensing 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. This condensation 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 solvents or industrial alcohol-based cleaners.

9. Avoid using the computer in strong sunlight, which will affect the function of the

touch screen.

10. 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.

11. The touch screen also does not function during the startup process, in Hibernate

mode and in Sleep mode or Safe mode.

12. Do not touch the screen with your finger or any other objects during the computer

startup or wake up process.
