DVD MECHANISM REPLACEMENT 1.Cautionary instructions in handling the assy (Safety instructions) Optical pickup The laser beam used in the pickup is classified as "class 2". Exposing your eyes or skin to the beam is harmful. Take care not to do so. (Caution against static electricity and leakage voltage) Ground securely the work tables, tools, fixtures, soldering irons (including those made of ceramic) and measuring instruments used in the production lines and inspection departments that handle loaders.
