First the case must be opened. Insert the blue plastic opening tool where the two casings meet. Pry up until you hear a clip pop and then carefully move around the device. Do this until the front and back casing are completely separate from one another.

You will again need to be careful opening the device in order to avoid damaging the speaker, or worse, the motherboard.

The clips holding the case together are roughly 1.5 in. apart.
