3.2  Screen buttons and controls 
The primary input channel of Clarion is the touch screen. If you read on, you will 
realise that most parts of the screen are not only used to display information but also 
to initiate functions by tapping. Below you will find a list of the most frequently used 
controls in the program. 
3.2.1  Direct selectors 
Some of the settings can be chosen from a short list of possible values. If the values 
can be described graphically, all values are available on the screen. 
 
Tap one of the icons to set/change the value.

 to move left in the list or tap 
 to move right. 
You need not confirm your selection. As soon as you leave the screen, the selected 
value becomes effective.

value.
