User Guide
2.3 Attentions when using the Touch Screen
1. With the new touch recognition technology of Touch Screen, the user only
needs to gently tap on the touch screen, and does not need to exert any
pressure to complete operations. When using it please remember not to use
excessive force or tear the screen surface with any sharp object.
2. In order to safeguard it for normal use, you should remove any dirt from the
touch screen, and ensure your fingers are clean and dry, as well as avoid using
it in dusty environments, or in very hot or humid conditions.
3. The product casing is easy to clean. To ensure safe use, we suggest you clean
the screen and casing with a soft cotton cloth after turning it off each time.
When wiping the screen, please do not wipe in an upwards direction, but wipe it
in a direction from top to bottom.
4. Please promptly remove any dust accumulated in the four corners of the screen
and the bottom of the screen frame, because this will prevent accumulated dust
from affecting the screen’s touch localization. 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.
Note: When it is used in normal operation, the touch screen process will
not affect the running of other computer processes.
