2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). 1.
2.2. Precaution of Laser Diode Caution: This product utilizes a laser diode with the unit turned “on”, invisible laser radiation is emitted from the pickup lens. Wavelength: 790 nm (CD) Maximum output radiation power from pickup: 100 µW/VDE Laser radiation from the pickup unit is safety level, but be sure the followings: 1. Do not disassemble the pickup unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pickup unit. It was already adjusted. 3.
2.3. Service caution based on Legal restrictions 2.3.1. General description about Lead Free Solder (PbF) The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this equipment in considering the globally environmental conservation. The normal solder is the alloy of tin (Sn) and lead (Pb).
2.4. Handling Precautions for Traverse Unit The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be taken avoid caution to electrostatic breakdown when servicing and handling the laser diode in the traverse unit. 2.4.1. Cautions to Be Taken in Handling the Optical Pickup Unit The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body.
2.5. Grounding for electrostatic breakdown prevention • As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working environment. Repair in the working environment that is grounded. 2.5.1. Worktable grounding • Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed and ground the sheet. 2.5.2.
