Parameter values can be entered using the 
numeric keypad, the scroll wheel and 
occasionally with the arrow keys. 
When prompted to enter a parameter, use the 
number keys (0~9), the decimal key (.) and the 
sign key (+/-) to enter a value. After a value 
has been entered, the soft-menu keys can be 
used to select the units.  
 
The value of the parameter is shown at the 
bottom of the screen as it is edited. Values can 
include decimal points for non-integer values 
or for entering dot-decimal notation for IP 
addresses.
