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.
