There is a lever on the left side bottom. Push it forward. There is even a little arrow that points forward an says "open" The left cover will rotate downward slightly Pull straight out and the cover will come off. There is no hinge or screw holding it on, so do it somewhere so that if you drop it, you can retrieve it.
