RX-Z1/DSP-AZ1 SERVICE MANUAL
For the details of RAV2000Z1 (U, C models), refer to the
RAV2000 SERVICE MANUAL #100770.
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
microprocessor supplied for servicing. Therefore, it is
necessary to write the program when the microprocessor
is replaced. (For the details, refer to "UPDATING
FIRMWARE".)

When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated INSULATING
from supply circuits. TABLE
G Meter impedance should be equivalent to 1500 ohm shunted G Leakage current must not exceed 0.5mA.
