Instructions
Turn your PSP off and place it face up on a sturdy work surface such as a table or desk. Locate the seam on the edge of the PSP LCD screen where the screen protector meets the side of the unit.
Insert the tip of your finger in the seam at the edge of the screen protector. Try to keep your finger off of the screen itself as you don't want to damage it.
Pull the screen protector gently off of the screen. It should peel away with very little effort. To replace the protector simply fit it over the screen, making sure it is even, and gently pat all the air bubbles out of it with your fingers.
