CONTRAST OF MISCELLANEOUS PARTSCONTRAST TABLE SC-57/UXJCB, SC-LX85/AXJ5 and SC-LX75/AXJ5 are constructed the same except for the following:Parts marked by NSP are generally unavailable because they are not in our Master Spare Parts List.The mark found on some component parts indicates the importance of the safety factor of the part.Therefore, when replacing, be sure to use parts of identical designation.Screws adjacent to mark on product are used for disassembly. For the applying amount of lubricants or glue, follow the instructions in this manual.(In the case of no amount instructions, apply as you think it appropriate.)Nos. indicate the pages and Nos. in the service manual for the base model.NOTES:When ordering resistors, first convert resistance values into code form as shown in the following examples.Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).5 6 14 7 3R 5 01 R 0RD1/4PU JRD1/4PU JRN2H KRS1P K56 x 10147 x 103 R501R0561473RN1/4PC F562 x 10156215261MarkNo.Symbol and Description SC-57/UXJCBSC-LX85/AXJ5SC-LX75/AXJ5RemarksPCB ASSEMBLIESP85-11.IR POWER AMP ASSYAWH7030AWH7042AWH7043NSP1.IR BUFFER ASSYAWM8249AWM8282AWM8282P85-2 2.IR BUFFER ASSYAWX9793AWX9952AWX9952NSP1.PRIM DISPLAY ASSYAWM8250AWM8266AWM8266P85-4 2.PRIMARY ASSYAWX9799AWX9852AWX9852P87-1 2.DISPLAY ASSYAWX9796AWX9967AWX9967P87-4 2.MIC HP ASSYAWX9800AWX9968AWX9968NSP1.AUDIO COMPOSITE ASSYAWR7106AWR7127AWR7128P83-2 2.AUDIO ASSYAWX9790AWX9986AWX9987P83-3 2.COMPOSITE ASSYAWX9791AWX9791AWX9836NSP1.INTERFACE REG ASSYAWR7111AWR7134AWR7134P81-3 2.IR REG ASSYAWX9806AWX9995AWX9995P81-4 2.B DIODE ASSYAWX9808AWX9958AWX9958P85-7 2.A REG BRIDGE ASSYAWX9810AWX9970AWX9970NSP1.REG BRIDGE ASSYAWR7112AWR7131AWR7133P81-6 2.DISPLAY BRIDGE ASSYAWX9815AWX9956AWX9956P81-7 2.F-IN BRIDGE ASSYAWX9816AWX9965AWX9965P83-9 2.MCH BRIDGE ASSYAWX9818AWX9818Not usedP83-11 2.MULTI CH IN ASSYAWX9857AWX9857Not usedP85-8 2.REG ASSYAWX9813AWX9991AWX9991P85-10 2.FB-CONNECT ASSYAWX9819AWX9966AWX9966P87-61.FRONT HDMI USB ASSYAWX9749AWX9969AWX9969P83-131.DAC HIGH ASSYAWX9822AWX9997AWX9999P83-141.DIGITAL MAIN ASSYAWX9827AWX9992AWX9993P83-151.COMPONENT ASSYAWX9866AWX9951AWX9867PACKING SECTIONP79-2AC Power CordADG7111ADG7105ADG7105P79-6Packing CaseAHD8722AHD8726AHD8733P79-9Operating Instructions (En)ARB7459Not usedNot usedOperating Instructions (Zhch)Not usedARC8003ARC8003P79-11Caution Sheet SPARM7083ARM7104ARM7104P79-12Operating Instructions (CD-ROM)ARU7006ARU7012ARU7026NSPP79-13Warranty CardARY7007ARY7118ARY7118RadioFans.CN 收音机爱 好者资料库3SC-LX8556785678ABCDEF Notes : For PCB ASSEMBLIES, Refer to “CONTRAST OF PCB ASSEMBLIES”.P79-14Remote Control Unit SEL/MIDAXD7612Not usedAXD7613P79-14RF Remote Control UnitNot usedAXD7580Not usedP79-15Battery DoorAZN8047Not usedAZN8047P79-15Battery CoverNot usedAZN8049Not usedNSPP79-17Dry Cell Battery (R3)VEM1051Not usedVEM1051NSPP79-17Dry Cell Battery (LR6)Not usedVEM1053Not usedIR Bluster CableNot usedADF7007Not usedRF Receiver BoxNot usedAXX7272Not usedRF Remote CautionNot usedARM7131Not usedNSPCCC S&E LabelNot usedDRW2310DRW2310EXTERIOR SECTIONP81-9Power Transformer (T1501)ATS7447ATS7448ATS7439P81-10Fuse (FU13, FU14 : 1A)REK1142Not usedNot usedP81-10Fuse (FU13, FU14 : T800mA)Not usedAEK7072AEK7072P81-11Fuse (FU11, FU12, FU15 : 1.25A)REK1143Not usedNot usedP81-11Fuse (FU11, FU12, FU15 : T1A)Not usedAEK7073AEK7073P81-12Fuse (FU10 : 4A)REK1149Not usedNot usedP81-12Fuse (FU10 : T3.15A)Not usedAEK1059AEK1059P81-24InsulatorAMR7198Not usedNot usedP81-24Insulator AssemblyNot usedDXA1904DXA1904REAR SECTIONP83-23Rear PanelANC8599ANC8603ANC8610P83-25D.
