1. Disconnect the speaker and microphone from the PCA. Disconnect the four-wire connector by pulling it upward (1).

2. Remove the screw. Loosen and remove the T-10 screw securing the plastic cover and bracket to the chassis.

3. Remove the shield and bracket. Lift the shield and place it upward (2).

4. Note the position of each speaker, microphone, and cables. The speaker is diagonally forward of the speaker bracket. The microphone fits into a well-formed recess in the enclosure.
