Be careful not to puncture or dent the battery with your screwdriver.

Use your Phillips screwdriver to remove four of the screws securing the loudspeaker:

Three 1.5 mm-long screws

One 3.0 mm-long screw

Use your tri-point Y000 screwdriver to remove the 1.3 mm-long screw securing a grounding contact and the loudspeaker.

Use your standoff screwdriver to remove the 3.4 mm-long screw securing the loudspeaker.

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.
