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

8、 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 represen

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

12、 bus.) IMPORTANT : Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit. Components having special characteristics are marked and must be replaced with parts having specification equal to those originally installed. LITHIUM BATTERY HANDLING

13、This product uses a lithium battery for memory back-up. WARNING : Lithium batteries are dangerous because they can be exploded by improper handling. Observe the following precautions when handling or replacing lithium batteries. Leave lithium battery replacement to qualified service personnel. Alway
