Use your Phillips #000 driver to remove the 1.3 mm screw securing the bottom right of the microphone.

Use a standoff driver to remove the two 3 mm standoff screws securing top of the microphone.

If you don't have a standoff driver, you may use a thin flathead driver—but be careful not to strip the shallow notches in the screw heads.
