Pulling the front case off, requires applying enough strength in the right areas.

The front case snaps into place in three places:

At the top and bottom of the battery side (opposite of side pictured) of the case.

Right in the middle of the DC-in side (side pictured) of the case.

Top of the camera, to the left of the power button.

Once those places are disconnected, the front case will pop right off.
