Using the touch screen
On the display that is touch-sensitive due to the touch sensor, application-specific user
interface elements, for example buttons, are displayed. When you tap the command button
with your finger, the function assigned to the button is activated.
The following types of pressure are permissible:
• Using a plastic pen with a 1 mm radius at the point: 25 g.
• Using a silicone finger with a diameter of 1.6 cm: 50 g.
Caution
Only touch one point on the touch screen and not several points at one time. You may
otherwise trigger unintended reactions.
Do not touch the screen in the following situations:
- During the booting process
- When plugging or unplugging USB components
- While Scandisk is running
Notice
Touching the touch screen with hard or pointed objects can damage the screen and thus
impair its functionality. Only operate the touch screen with your fingers (even with gloves) or
approved touch pens.
