1 Safety Precautions 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 barriers, insulation papers shields are properly installed.
2 Warning 2.1. Prevention of Electro Static Discharge (ESD) to Electrostatically Sensi- tive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip”...
2.2. Precaution of Laser Diode CAUTION : ACHTUNG : This product utilizes a laser diode with the unit turned "ON", Dieses Produkt enthält eine Laserdiode. Im eingeschalteten invisible laser radiation is emitted from the pick up lens. Zustand wird unsichtbare Laserstrahlung von der Laserein- Wave length : 662 nm(DVDs)/780 nm(CDs) heit abgestrahlt.
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).
