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 REASON WHAT SO 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. 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 all service required should be performed by an authorized Yamaha Retailer or the appointed service representative. IMPORTANT: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 belived 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 distributors Service Division. WARNING: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 wires connect to this bus). IMPORTANT:Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit. WARNING Components having special characteristics are marked and must be replaced with parts having specification equal to those originally installed. IMPORTANT NOTICE FOR THE UNITED KINGDOM Connecting the Plug and Cord IMPORTANT.The wires in this main lead are coloured in accordance with the following code: BLUE:NEUTRAL BROWN: LIVE As the colours of the wires in the main lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The BLUE wire must be connected to the terminal that is marked with the letter N (or coloured BLACK). The BROWN wire must be connected to the terminal that is marked with the letter L (or coloured RED). Be certain that neither core is connected to the earth terminal of the three pin plug. This set employs a laser. Therefore, be sure to carefully follow the instructions below when servicing. When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens. Laser Diode Properties Material:AlGalnP Wavelength:675695nm Emission Duration:Continuous Laser Output Power:Less than 44.6 W (Note) Laser output is measured at a distance of 20 cm from the object lens on the optical pick-up head. PROTECTION OF EYES FROM LASER BEAM DURING SERVICING D24 3 WARNINGLaser Safety This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precaution must be used during servicing of the unit. 1) When testing and / or repairing any component within the product, keep your eyes and skin more than 30 cm away from the laser pick-up unit at all time. Do not stare the laser beam at any time. 2) Do not attempt readjustment, disassemble and repair of the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION - Use of controls or readjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
