  Press the "Alternat." softkey or the "Select" key until the required 
unit is displayed. 
The "Alternat." softkey is only visible when you have a choice of units

  Press the "Backspace" or "Del" key. 
 
 
 
Changing or calculating 
parameters 
 
If you only want to change individual characters in an input field rather 
than overwriting the entire entry, switch to insert mode. In this mode, 
the pocket calculator is also active. You can use it during 
programming to calculate parameter values. 
 
 
  Press the "Insert" key. 
Insert mode and the pocket calculator are activated.  
You can move around within the input field using the "Cursor left" and 
"Cursor right" keys. 
Use the "Backspace" or "Del" key to delete individual characters. 
For more information on the pocket calculator, see Sec. "Pocket 
calculator". 
 
 
Parameter: Accepting 
 
When you have correctly entered all the necessary parameters in the 
parameterization screen form, you can close the screen form and 
save the parameters.  
 
 -or-   
  Press the "Accept" softkey or the "Cursor left" key. 
If there are several input fields in a line and you want to use the 
"Cursor left" key to accept the parameters, you must position the 
cursor in the leftmost input field. 
You cannot accept the parameters if they are incomplete or obviously 
erroneous. In this case, you can see from the dialog line which 
parameters are missing or were entered incorrectly.
