SERVICE MANUAL AV RECEIVER/AV AMPLIFIER RX-Z1/DSP-AZ1 100798 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 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 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.

RX-Z1/DSP-AZ1 RX-Z1/DSP-AZ1 1 WALL OUTLET EQUIPMENT UNDER TEST AC LEAKAGE TESTER OR EQUIVALENT INSULATING TABLE WARNING: CHEMICAL CONTENT NOTICE! 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 REA- SON WHATSOEVER! 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. I TO SERVICE PERSONNEL 1. Critical Components Information Components having special characteristics are marked s and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. GMeter impedance should be equivalent to 1500 ohm shunted by 0.15F. I IMPEDANCE SELECTOR IMPEDANCE SELECTOR WARNING: Do not change the IMPEDANCE SELECTOR switch setting while the power to this unit is on, otherwise this unit may be damaged. “CAUTION” “F701, 702: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.” “F751: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 12A, 250V FUSE.” “F752: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V FUSE.” CAUTION F701, 702: REPLACE WITH SAME TYPE 6A, 125V FUSE.

RX-Z1/DSP-AZ1 RX-Z1/DSP-AZ1 178 I UPDATING FIRMWARE / 更新方法 To update the firmware, use the application software (Z1Flash.exe) for installation. It is a program rewriting tool intended for the following models. RX-Z1, DSP-AZ1 This application software is applicable only to the special format (.mot) program made open to the public for upgrading the version. Connecting terminal Use the RS-232C terminal provided on the rear panel of the main unit.

It is not possible to write if any other cable is used. If installation has failed due to the use of any other cable by mistake, the unit will not operate, e.g., the power to the amplifier will not turn on. If such is the case, reconnect using the cross cable of the above specification with disconnecting the power cord of the amplifier from the outlet and execute writing again. Never disconnect the power cord to the main unit until installation is completed. When the power cord is disconnected by mistake during the installation process, perform the procedure all over again. 更新、用 （Z1Flash.exe） 使用行。 、下記対象 書換。 DSP-AZ1、DSP-AX1UG 、公開 専用 （.mot） 適用可能 。 接続端子 製品本体装備RS-232C端子使用 。 必要 DOS/V機、OS: Windows 95 / 98 、付 (RS-232C) PC 書込用 （Z1Flash.exe） 公開 （.mot） RS-232C “D-sub 9 pin” （仕様） Pin No.2 RxDPin No.2 RxD Pin No.3 TxDPin No.3 TxD Pin No.5 GNDPin No.5 GND Pin No.7 RTSPin No.7 RTS Pin No.8 CTSPin No.8 CTS 市販品例 Arvel社AR315 （2m） AR327 （3.5m） ELECOM社C232R-S1.5 （1.5m） C232R-S3.0m （3m） 作業上注意 必、上記仕様使用。 他書込。誤上記仕様 以外使用、失敗場合 、電源入等動作。 場合、電源抜 、上記仕様接続直、再書 込行。 途中、製品本体電源絶対 抜。 誤途中電源抜場合、 作業最初直。 RX-Z1/DSP-AZ1 RX-Z1/DSP-AZ1 179 Preparation and cautions to take before the basic operation Download the following items from the specified download sources to the PC for upgrading the version.
