Touch screen instruction

(Refer to these instructions if your computer is equipped with a touch screen.)

A touch screen is a computer display screen that is also an input device. The screens are sensitive to pressure; allowing a user to interact with the computer by touching pictures or words on the screen.

Attention:

• This computer is equipped with a resistive touch screen panel coated with a thin metallic electrically conductive and resistive layer that causes a change in the electrical currents that are registered as touch events and sent to the controller for processing. The resistive layer can be damaged by sharp objects.

• Touch the resistive touch screen with your ﬁngers only. Do not use a stylus to touch the resistive touch screen panel.

• The cursor may not move quickly when it is dragged.

• The touch screen does not function in Rescue System mode.
