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.
1.4. Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: No sound is heard when the power is turned on. Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
1.6. Safety Parts Information Safety Parts List: There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Exploded View & Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent shock, fire or other hazards.
2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatic Sensitive (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: 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 W/VDE Laser radiation from the pickup unit is safety level, but be sure the followings: 1.
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. Cautions to Be Taken in Handling the Optical Pickup Unit 2.4.1.
Grounding for electrostatic breakdown prevention 2.4.2. Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electric- ity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 2.4.2.1.
