SUBWOOFER SYSTEM YST-SW012 IMPORTANT NOTICE This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel. It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understood by the users, and have therefore not been restated. WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any service required should be performed by an authorized YAMAHA Retailer or the appointed service representative. IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form. The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division. WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss). IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. G Meter impedance should be equivalent to 1500 ohms shunted by 0.15µF. “CAUTION” “F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 1.6A, 125V FUSE.” CAUTION F1: REPLACE WITH SAME TYPE 1.6A, 125V FUSE. ATTENTION F1: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 1.6A, 125V. WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA- SON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. G Leakage current must not exceed 0.5mA. G Be sure to test for leakage with the AC plug in both polarities. About Lead Free Solder Side A Side B SMT REFLOW Process MI FLOW Process Solder Dip Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work. • Sn + Ag + Cu (tin + silver + copper) • Sn + Cu (tin + copper) • Sn + Zn + Bi (tin + zinc + bismuth) Caution: 1. As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder. 2. If lead solder must be used, be sure to remove lead free solder from each terminal section of the parts to be replaced and from the area around it completely before soldering, or make sure that the lead free solder and lead solder melt together fully. The P.C.B.s installed in this unit are soldered using the following solder. MAIN P.C.B.

Disconnect the power cable from the AC outlet. 1. Removal of Front Grille Ass’y * The Front Grille Ass’y is fixed to the cabinet with dowels at 5 locations. As a flatblade screwdriver is used for removal, use special care not to cause damage to the Cabinet Ass’y. a. Using the flatblade screwdriver inserted in the gap between the Front Grille Ass’y and the Cabinet Ass’y (bottom side first), push up the Front Grille Ass’y. (Fig.1) b. Remove the Front Grille Ass’y by lifting a metalblade up. (Fig.1) * When installing the Front Grille Ass’y, apply quick-drying bond or the like to dowels and then fit them into dowel holes for secure installation. (The Front Grille Ass’y will come off easily if its dowels are fitted into dowel holes without applying quick- drying bond or the like.) 2. Removal of Driver a. Remove 4 screws (1) and remove the Driver. (Fig.1) b. Disconnect the connector connected to the terminal of the Driver. (Fig. 1) 3. Removal of Rear Panel Ass’y a. Remove 8 screws (2) and remove the Rear Panel Ass’y. (Fig.1) * Screws (2) are identified with arrow marks ( ).
