INSTRUCTIONS FOR HANDLING SEMI-CONDUCTORS AND OPTICAL UNIT
Electrostatic breakdown of the semi-conductors or optical pickup may occur due to a potential difference caused by
electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1 M Ω ) that is properly grounded to remove any static electricity that may be
charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with proper grounding (1 M Ω ) on the workbench or other surface,
where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through
the body grounding band, be careful to avoid contacting semi-conductors with your clothing
