Remove Seal

To get to the screw, we need to scratch off the warranty seal. Yes, this means you'll void your warranty. Use the screwdriver or your fingernails to gently remove it.

  Remove Screw

Under the seal, you`ll find the screw that holds the casing together. Take your screwdriver and remove it. Only apply gentle pressure. If it doesn't move, try the other way round (remember unscrewing is counterclockwise)

 Open hull

Now firmly pull apart the back of the hull as shown on the image (click it for a larger version). The hull will stick together at the front. If it doesn't move, make sure that the screw is completely removed. You can also try to gently stick your screwdriver between the two parts. Again, don't use too much force or you could break the hull. Now move the upper hull backwards as shown on the image.
