29、r the human body. Use cautionto prevent electro static damage when servicing or handling the DVD-mechanism.1. Grounding for electro static damage preventionSome devices, such as the DVD player, use an optical pickup (laser diode) that will be damaged by static electricity in theworking environment.

30、Only attempt service after ensuring that all grounding procedures have been completed.1. Worktable groundingPut a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.2. Human body groundingUse an anti-static wrist strap to discharge the static electricit
