RX-Z9/DSP-Z9                                                                               SERVICE MANUAL
                                                                            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.




Please note that no program is written into the micropro-
cessor supplied for servicing. Therefore, it is necessary to
write the program when the microprocessor is replaced.
