Replacing the fuses This symbol located near the fuses indicates that thefuse used is fast operating type. For continued protection againstfire hazard, replace with same type fuse. For fuse rating refer tothe marking adjacent to the symbol. Ce symbole indique que le fusible utlise est a rapide.Pour une protection permanente, nuntiliser que fusibles dememe type. Ce darnier est la qu le present symbol estappse.CIRCUIT NO. PART NO. DESCRIPTION2. To initialize the unitThis device employs a microprocessor to perform variousfunctions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions tooperate abnormally.To perform a result, please follow the procedure below.1.Press and hold down the VIDEO-1 button, then press the STANDBY button.2.After Clear is displayed, the preset memory and eachmode stored in the memory, such as surround, areinitialized and will return to the factory setting.4. Changing the AM band stepWith the exception of the worldwide models, a tuning step selectorswitch is not provided. When you change the band step, changethe parts as shown below. To 10kHz To 9kHzR714 Open 10 k3. Safety-check out(U.S.A. model only)After correcting the original service problem, perform thefollowing safety check before releasing the set to the customer.Leakage Current CheckMeasure leakage current to a known earth ground(water pipe,conduit, etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the appliance(input/output terminals, screwheads,metal overlays, etc.).DTR-4.6F6901,F6902 F901F903 F931,F932 F951,F952252301GR12A-TUL-250V,Fuse252330GR10A-UL/T-233,Fuse 252326GR5A-UL/T-233,Fuse 252073GR1.6A-SE-EAK,Fuse252257GR4A-T/UL-ST2,FuseDTR-4.6A12345BCDEFGHEXPLODED VIEWQ6050Q6051Q6053Q6052Q6054Q6060Q6061Q6063Q6062Q6064A095U063A081A050A052T901A065A051F6901F901F903F6902A077A090A059A401U044U04U02U06U062U045U03U032U11U042P701F951F952F932F931U043Q6050ax 10 sheetsA083A100 x 4 pcs.A105x 2 pcs.A056 x 4 pcs.A105x 3 pcs.A105x 3 pcs.A105x 4 pcs.A082x 10 pcs.A037A402x 44 pcs.A119x 4 pcs.A111x 4 pcs.A114x 4 pcs.A054x 3 pcs.A053x 3 pcs.A055x 9 pcs.A101 x 4 pcs.A080A110U08A099A063A105x 2 pcs.A083A067A044x 4 pcs.A040A019A015A003A008A010A009A410A005A001A012P7534U073U075U07A037 x 3 pcs.A003x 6 pcs.A011x 2 pcs.A003 x 2 pcs.A003x 2 pcs.A012x 2 pcs.A003x 11 pcs.A020A020A089A002A096A405A409x 3 pcs.A420U048A068U049U065DTR-4.6BLOCK DIAGRAMAMPLIFIER SECTIONSOURCE_RSOURCE_LZ2_LZ2_RTAPE_OUT_LTAPE_OUT_RMIX_LMIX_RVOLIN_SBLVOLIN_SBRV1_OUT_RV2_OUT_LV2_OUT_RV1_OUT_LADLT+ADLT-ADRT-ADRT+MCH_CTMCH_SWMCH_SLMCH_SRADLT-ADLT+ADRT+ADRT-TXRX5RX2RX7RX6RX4DAC_FRDAC_FLDAC_SWDAC_SLDAC_SRDAC_SBLDAC_CTDAC_SBRMCLKLRCLKBCLK-6dBNJW1157+9.7dB-6dB Inv.NJU7311AMTTBTUNER PACKVIDEO1 INVIDEO1 OUTVIDEO2 OUTVIDEO2 INTAPE INTAPE OUTCDDVDMC/MSWMSL/MSRVIDEO3 INVIDEO4 INANTENNA UNITXM/DT ICAK4384DACMicroControllerXM-RADIOCOAX 2COAX 1OPT2OPT3OPT OUTOPT12ch ADC2ch ADCCS5340LPFLPFLPFLPFLPF2ch ADCDIR8ch DACDSPCS494003SD_RAMIC42S161002M ByteFLASH ROMMX29LV0404M BitCS4152823480818287838488899095919247484546111012894244302829272126242225234341706968676665646362615958576085939486719172119202429282723226526255152535455567172737430313233363735342829161413154948434247464544508182807986851275660616362641181101091106107117111325954119134131AA+AAQ3003Q331,341Q211Q285Q201Q361Q3002Q3004A12345BCDDTR-4.6BLOCK DIAGRAMAMPLIFIER SECTIONZ2RLCSRLFRLZ2R_POZ2L_POAMUTHPMUTZ2LMUTRS232CINTERFACERS232CFRONT LEFTFRONT RIGHTCENTERSURR.
