Insert a plastic opening tool into the back cover and the housing of the body.

Use the plastic opening tool to pop open the clamps that hold the casing onto the back cover.

Work your way around the all sides to completely take off the back cover.

You may use your fingers to help remove the cover.

Carefully lift the back cover. Do not use excessive force to lift it. If it feels like it will not pull up, make sure all the screws have been taken out.
