you probably have to have the PC data cable plugged into the radio?
That menu setting is to tell the radio how you want to use the speaker 
mike/data jack on the side...
Though not for programming since I think it's automatic when you connect the 
radio to the computer and read/write to it using the software.  I suspect PC 
mode is for use with external packet or GPS devices.
