The pin does not need to be removed from the sound processor. As
long as the tool is pushed in flush on one side of the sound processor,

at the top near where it connects with the sound processor and pull
forward until it is separated from the sound processor.

houses the microphone. Align the bottom of the T-Mic with the T-Mic
cover. Gently turn the M T-Mic into the T-Mic cover. Screw until they are
flush with one another.
