the system user’s manual so you can access the controller.
3. Ground yourself before you touch the controller.
4. Unplug all cables from the controller, remove the screw attaching the
bracket to the computer case, and carefully remove the controller
from the slot.
5. Place the controller on a flat, clean, static-free surface, and continue
