2.1.2 TOUCH-SCREEN USE
The interface has a resistive touch-screen LCD with sensitive areas applied to the contextual content of the active screen.
It allows you to select items or perform functions with ease.
Do not exert too much pressure on the touch screen with your fingers and do not use a sharp object on the touch screen. Doing so
may damage the touch screen or cause it to malfunction.
It is advisable to exert weaker pressure and not too fast on the screen and to become familiar with the use of the touch-screen
itself, well calibrating the touch of your fingertip on the sensitive areas of the screens.
Do not put the touch-screen in contact with other electrical devices. Electrostatic discharge may cause a malfunction.
