With a Phillips screwdriver (PH # 00), we remove the eight screws from the speaker and vibrator module, and with a thin plastic tool we remove it from its housing.

By mistake the battery is lodged in its place, despite having removed it in the previous step.

Once the module is removed, we will remove the vibrator with a fine tool.
