Hold the Kindle in two hands with the back of the device facing you. Ensure you are holding the Kindle such that your fingers are not pressing on the screen.
Turn off the power to the Kindle. The power button is located on the back of the Kindle close to the rear outside of the unit.
Locate the rear panel that slides off the device. One edge of this panel will wrap around the edge of the Kindle. Hold the device so that this side of the rear panel is facing away from you.
Press down firmly with your thumbs on the edges of this panel and push the panel away from you. It should slide off gently.
