2 IMPRTANT NTICE 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 under stood by the users, and have therefore not been restated. WARNING: IMPRTANT: Failure to follow appropriate service and safety procedures when servicing this product may result in per-sonal injury, destruction of expensive components and failure of the product to perform as specified. For these reasons, we advise all Yamaha product owners that all service required should be performed by an authorized Yamaha Retailer or the appointed service representative. This presentation or sale of this manual to any individual or firm does not constitute authorization, certification, recognition of any applicable technical capabilities, or establish a principal-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 changes in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact the distributor s Service Division. WARNING: IMPRTANT: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the ground bus in the unit (heavy gauge black wiresonnect to this bus). Turn the unit FF during disassembly and parts replacement. Recheck all work before you apply power to the unit. WARNING: CHEMICAL CNTENT NTICE! 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. D NT PLACE SLDER, ELECTRICAL/ELECTRNIC R PLASTIC CMPNENTS IN YUR MUTH FR ANY REASN WHAT S EVER! 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. IMPRTANT NTICE FR THE UNITED KINGDM Connecting the Plug and Cord WARNING: THIS APPARATUS MUST BE EARTHED IMPRTANT. The wires in this mains lead are coloured in accordance with the following code: GREEN-AND-YELLW: EARTH BLUE: NEUTRAL BRWN: LIVE As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug proceed as follows: The wire which is coloured GREEN-and-YELLW must be connected to the terminal in the plug which is marked by the letter E or by the safety earth symbol or colored GREEN or GREEN-and-YELLW. The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BRWN must be connected to the terminal which is marked with the letter L or coloured RED. This applies only to products distributed by Yamaha-Kemble Music (U.K.) Ltd. ( wires) WARNING Components having special characteristics are marked installed. and must be replaced with parts having specification equal to those originally
