Use a JIS #1 screwdriver to loosen the seven screws from the back panel.

Turn each screw counter-clockwise at least 3 turns and move on to the next step.

Screws will not come out of the panel, so you don't have to worry about losing them.

Place the end of a spudger or opening tool into the seam to gently separate the back cover from the rest of the device.

Slide the opening tool around the perimeter of the device to release the clips that hold the back panel to the device.

Remove the back panel.
