Remove all nine screws from the bottom of the device using a T5 screwdriver.

Remove two additional screws, if present, from beneath the rubber pads. (Pry up each rubber pad to access its screw.)

Carefully remove the bottom cover. The cover doesn't just lift up, you have to lift it to a approx. 45° angle, then pull towards the exterior (there are two small plastic claws that maintain the cover attached)
