    1. SAFETY PREAUTIONS 1.1 GENERAL GUIDELINES 1. When servicing, observe the original lead dress. if a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barrier, insulation papers shields are properly installed.

    4.PREVENTION OF STATIC ELECTRICITY DISCHARGE The laser diode in the traverse unit (optical pickup)may brake down due to static electricity of clothes or human body. Use due caution to electrostatic breakdown when servicing and handling the laser diode. 4.1.Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup(laser diode)and the optical pickup will be damaged by static electricity in the working environment.Proceed servicing works under the working environment where grounding works is completed.
