Ensure the face-plate lock is in the "Unlocked" position.

Pry the face plate off of the body by gently prying with an opening tool near the marked locations. The face plate should not be difficult to remove.

You can pry the face plate away with your fingers, or with any plastic/wooden tool.

Avoid using metal tools to pry the plastic face plate away, as it can lead to marring the plastic and ruining the finish.
