+	    connector. Locate this and place the LED on the MicroPeak
+	    directly in contact with it. The MicroPeak LED and the
+	    MicroPeak USB adapter photo need to be touching—even a
+	    millimeters of space between them will reduce the light
+	    intensity from the LED enough that the phototransistor
+	    will not sense it. Turn on the MicroPeak board and adjust
+	    the position until the blue LED on the MicroPeak USB
+	    adapter blinks in time with the orange LED on the
+	    MicroPeak board.
