User's Manual

When you use the mouse frequently, clean the roller about every two

weeks. First remove the roller cover. If you have an Epson mouse, turn it

over, push the roller cover to the side, and lift the cover out. (If you have

another type of mouse, turn the cover counterclockwise to remove it.)

Then remove the roller, wipe it with a clean, dry cloth, and replace the

roller and cover. There are no other user-serviceable parts inside the

mouse.
