    • Remove the two triangular pads at the top of the two speakers.

    • These pads have adhesive to keep them situated, so you may want to use a fine-tipped object, such as a screwdriver or a pen, to remove them. It is easiest to place the fine-tipped object in the small indent in the corner of these pads.
