Tips for using the touch screen
The whole screen responds to touch. To choose an option, tap with a
fingernail, fingertip, an eraser or a specialised stylus. Do not touch the
screen with sharp objects, such as the tip of a ballpoint pen.
• Do not place anything on top of the screen, to prevent damage or
scratching on the screen.
• Press buttons, words or icons to select them.

and hold the scroll bar, then move up or down to move through the
list.

been successfully selected, it will be displayed as reversed text
(light text on a dark background).
