Forthese reasons, we advise all YAMAHA product owners that any service required should be performed byan 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, certifica-tion or recognition of any applicable technical capabilities, or establish a principle-agent relationship ofany 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 toexist, please contact the distributors Service Division.WARNING:Static discharges can destroy expensive components. Discharge any static electricity your body may haveaccumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to thisbuss).IMPORTANT:Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power tothe unit.RX-E810/RX-E410/NX-E800 2006 All rights reserved.This manual is copyrighted by YAMAHA and may not be copied orredistributed either in print or electronically without permission.P.O.Box 1, Hamamatsu, Japan 06.07RX-E810/RX-E410/NX-E800MICRO COMPONENT SYSTEM MCR-E810/MCR-E410RadioFans.CN 收音机爱 好者资料库RX-E810/RX-E410/NX-E8002RX-E810/RX-E410/NX-E800I TO SERVICE PERSONNEL1. Critical Components InformationComponents having special characteristics are marked sand must be replaced with parts having specifications equalto those originally installed.2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.GMeter impedance should be equivalent to 1500 ohms shuntedby 0.15F.WALLOUTLETEQUIPMENTUNDER TESTAC LEAKAGETESTER OREQUIVALENTINSULATINGTABLEWARNING: CHEMICAL CONTENT NOTICE!The solder used in the manufacturing process except soldering of the P.C.B. assy contains LEAD. In addition, otherelectrical/electronic and /or plastic (where applicable) components may also contain traces of chemicals found by theCalifornia Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductiveharm.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 exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.“CAUTION”“F1, F2: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 3.5A,125V FUSE.”CAUTIONF1, F2: REPLACE WITH SAME TYPE 3.5A, 125V FUSE.ATTENTIONF1, F2: UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 3.5A, 125V.About Lead Free SolderThe P.C.B.s installed in main unit are soldered using the all lead free solder.Among some types of lead free solder currently available, it is recommended to use one of the following types for the repairwork. Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)Caution:As the melting point temperature of the lead free solder is about 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.RadioFans.CN 收音机爱 好者资料库RX-E810/RX-E410/NX-E8003RX-E810/RX-E410/NX-E800I SYSTEM COMPOSITIONThe MCR-E810 consists of the DVD-E810, RX-E810 and NX-E800.The MCR-E410 consists of the CDX-E410, RX-E410 and NX-E800.MCR-E810 (U, C, T, K, A, B, G, L, V models)DVD-E810RX-E810NX-E800 x 2CDX-E410RX-E410NX-E800 x 2MCR-E410 (B, G models)RX-E810/RX-E410/NX-E8004RX-E810/RX-E410/NX-E800RX-E410 (B, G models)NX-E800 (U, C, T, K, A, B, G, L, V models)I FRONT PANELSI REAR PANELSRX-E810 (T model)RX-E810 (U, C models)RX-E810 (A model)RX-E810 (K model)RX-E810 (U, C, T, K, A, B, G, L, V models)RX-E810/RX-E410/NX-E8005RX-E810/RX-E410/NX-E800RX-E810 (V model)RX-E810 (L model)RX-E810 (G model)RX-E810 (B model)RX-E410 (B model)RX-E410 (G model)RX-E810/RX-E410/NX-E8006RX-E810/RX-E410/NX-E800I REMOTE CONTROL PANELSNX-E800RX-E810(U, C, T, K, A, L, V models)RX-E810(B, G models)RX-E410(B, G models)7RX-E810/RX-E410/NX-E800I AUDIO SECTIONMinimum RMS Output Power (Power Amp. section)20 Hz to 20 kHz, 0.1 % THD, 6 ohms. 40 W + 40 W1 kHz, 0.1 % THD, 6 ohms . 55 W + 55 WDynamic Power Per Channel (IHF)6 ohms . 60 W + 60 W4 ohms . 75 W + 75 W2 ohms . 100 W + 100WMax Power Per Channel (B, G models)1 kHz, 0.7 % THD, 4 ohms . 60 W + 60 WIEC Power (B, G models)1 kHz, 0.04 % THD, 6 ohms . 55 W + 55 WMaximum Useful Output Power (JEITA) (L, V models)1 kHz, 10 % THD, 6 ohms (L, V models). 65 WPower Band Width (0.1 % THD, 30 W, 6 ohms)FRONT L/R. 10 Hz to 50 kHzDamping Factor20 Hz to 20 kHz, 6 ohms . 60 or moreInput Sensitivity/Input ImpedanceRX-E810DVD, etc. .150 mV / 47 k-ohmsRX-E410CD, etc.150 mV / 47 k-ohmsMaximum Input Voltage (1 kHz, 0.5 % THD)RX-E810DVD, etc. . 3.0 V or moreRX-E410CD, etc. 3.0 V or moreRated Output Voltage/Output ImpedanceSUBWOOFER .2.0 V / 680 ohmsREC OUT .150 mV / 1.2 k-ohms or lessHeadphone Jack Rated Output/ImpedanceRX-E810DVD, etc. (1 kHz, 150 mV, 8 ohms) .0.23 V / 120 ohmsRX-E410CD, etc. (1 kHz, 150 mV, 8 ohms) .0.23 V / 120 ohmsFrequency Response (20 Hz to 20 kHz)RX-E810DVD, etc. .0 0.5 dBRX-E410CD, etc.0 0.5 dBTotal Harmonic Distortion (20 Hz to 20 kHz, 30 W/6 ohms)RX-E810DVD, etc. to SP OUT . 0.04 % or lessRX-E410CD, etc. to SP OUT. 0.04 % or lessSignal to Noise Ratio (IHF-A Network)RX-E810DVD, etc., Input shorted (150 mV) . 93 dB or more(250 mV). 98 dB or moreRX-E410CD, etc., Input shorted (150 mV) . 93 dB or more(250 mV) . 98 dB or moreResidual Noise (IHF-A Network)Pure direct on . 100 VI SPECIFICATIONSChannel SeparationRX-E810DVD, etc., Input 5.1 k-ohms shorted, 1 kHz / 10 kHz. 60 dB / 45 dB or moreRX-E410CD, etc., Input 5.1 k-ohms shorted, 1 kHz / 10 kHz.60 dB / 45 dB or moreTone Control CharacteristicsBASS: Boost/Cut . 10 dB (50 Hz)Turnover Frequency. 350 HzTREBLE : Boost/Cut . 10 dB (20 kHz)Turnover Frequency.3.5 kHzGain tracking error (0 to -60 dB) . 2 dB or lessI FM SECTIONTuning RangeU, C, L, V models. 87.5 to 107.9 MHzT, K, A, B, G, L, V models . 87.50 to 108.00 MHz50 dB Quieting Sensitivity (IHF) (1 kHz, 100 % MOD.)Mono . 2.8 V (20.2 dBf)Signal to Noise Ratio (IHF)Mono / Stereo . 73 dB / 70 dBHarmonic DistortionMono / Stereo (1 kHz). 0.5 % / 0.5%Antenna Input. 75 ohms unbalancedI AM SECTIONTuning RangeU, C, L, V models. 530 to 1710 kHzT, K, A, B, G, L, V models . 531 to 1611 kHzAntenna.Loop antennaI GENERALPower SupplyU, C models.

Starting DIAG in the protection cancel modeIf the protection function works and causes hindrance to trouble diagnosis, cancel the protection function as describedbelow, and it will be possible to enter the DIAG mode. (The protection functions other than the excess current detect functionwill be disabled.)Press the “STANDBY/ON” key while simultaneously pressing those two keys indicated in the figure above. At this time, keeppressing those two keys for 3 seconds or longer.In this mode, the “SLEEP” segment of the FL display of the main unit flashes to indicate that the mode is DIAG mode with theprotection functions disabled.CAUTION!Using this product with the protection function disabled may cause damage to itself.
