To open the device, the sides must be (with moderate force) pried apart using a prying tool as seen in the picture.

Both sides must be separated from one another.

Tip: The right side may be slightly more difficult. It will be easiest to begin on the left.

Beginning with the left side, gently pry at the division of the face plates until they separate from one another.

Repeat this process on the other side of the device.
