As you reach around from the front to the back of the device, from left to
right, there is the Power button (left), an SD card slot (middle), and a Micro
B USB port (right). (Image is reversed in photo.) They are all recessed in an
area in the left half of the back edge. The Power button sticks out enough to
make it easy to identify. The SD card slot has two small bumps directly
below it and the USB port has one bump below it.
The SD card slot is a standard type with spring feedback. The SD card is
inserted with the card connector fingers facing down. To release the card,
press in and remove your finger to allow the card to pop out.
The battery compartment is located on the bottom of the device.
