Professional that has been upgraded from an earlier version of Windows, correct 
operation cannot be guaranteed. 
 It may not be possible to use the mouse function under some versions of both the 
Windows and Macintosh operating systems.
 Some computer settings may have to be changed in order for the mouse function to be 
used. Consult the documentation for the computer for further details.Computer Mouse used Applicable cable
