Remove the four 12mm phillips head #2 screws located along the outer edge of the white case.

Be careful! There are two small, easily-broken, plastic tabs at the bottom of the device keeping it together.

Once you remove the screws, pick the device up so that the grey label on the bottom of the device faces toward you.

With your thumbs on either side of the grey label, slowly push with both thumbs until the case pops open.

A small gap will open as the two tabs are released.

Do not pull the two halves apart yet. They are held together by the speaker wire.
