- The MicroPeak USB adapter has a small phototransistor on
- the end of the board furthest from the USB
- 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.

+ Locate this, turn on the MicroPeak and place the orange LED on the MicroPeak
+ directly inside the hole, resting the MicroPeak itself on
