Look at the board from the top, with the speaker cut-out to the lower  
right.  Now notice the lower left corner.  You'll see holes (i.e.,  
solder points or "pads") for "GND" and "AF."  The "AF" solder point  
is the AF pad.  It's where the audio line from the K2 connects to the  
board.

I just finished a KPA100, and I have to admit that description  
stumped me for a moment, also.
