2.3 Precautions when using Lenovo Touch
1. With the new touch recognition technology of Lenovo Touch, 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 ensure normal use, you should remove any dirt from the touch
screen, and ensure your fingers are clean and dry, and avoid using it in dusty
environments, or in very hot or humid conditions.
3. The product case is easy to clean. To ensure safety, please clean the screen
and frame with a soft cloth after turning the computer off. Note that when
wiping the screen, wipe it from top to bottom, and do not wipe upwards.
4. Remove in time any dust accumulated in the four corners of the screen and the
bottom of the screen frame, so as to prevent accumulated dust from interfering
the touching and positioning function of the screen. Do not place or drop any
obstructive object in the four corners of the screen or any part of its frame, so as
to prevent the screen from being unable to locate positions due to obstruction.
5. This touch screen is supplied with related configuration software, which will
consume a reasonable amount of CPU resources when the touch screen is in
use.
Notes: When it is used in a normal way, the touch operations will not affect
the execution of other computer processes.
