Removing Board From Tray:
-------------------------
6.) Unfasten screw located between YCL0425 and 0444|LF-H17X-2
7.) Slide PCB board down to line up with keys
8.) Remove PCB board from tray
9.) Photograph PCB board bottom
-----------------------------------------------------------
Exposing Radios
---------------
10.) Loosen RF shielding at ten points around each shield
* use fine blade screwdriver (flat head) to twist-pry for loosening

11.) Carefully remove shielding, exposing both radios
* note that the top radio shield has a square of material on the inside opposite (farthest away) from the Atheros chip;  the bottom radio shield does not have this material
