Lifting primarily from the device's left side, you may begin to pull off the face of the device. Watch and be careful to let the headphone jack slide away from it's opening in the back plate.

The cover lifts free revealing that all of the internals are stacked on the face of the machine!

Notice that the frames of the power button and hold switch are affixed to the back plate.

Admire the tight, efficient (looking at least) engineering.
