Contents of AMP test mode(1) Automatic POWER ONEThe POWER ON state is entered whenever the power isturned on while pressing the BAND key. All functions arethen initialized and activated in the all-lighting mode.ESub-clock oscillation diagnosis functionThe oscillation diagnosis (existence of oscillation andmeasurement of period) of a sub-clock is performedbefore the test mode is entered. If the diagnosis result isOK, the system enters the test mode.If the diagnosis result is NG, the oscillation of the sub-clock is diagnosed again. If the result is OK, the systementers the test mode. If the diagnosis result is continu-ously NG five times, the system stops with ERR 1 andERR 2 displayed.(2) All-lighting modeEAll the fluorescent display indicators and LED lamps lightwhen the power is turned on while pressing the BANDkey.E After that, the all-lighting mode is canceled when anymain units key is pressed. The normal display obtainedwhen the selector is set to TUNER then appears.(4) OthersEThe AMP test mode is not terminated even if the selectoris set to positions other than TUNER.EIn the AMP test mode, the muting during mode selectionis not controlled. However, the operation during thepower-on sequence is the same as the normal operation.EThe SP protection operation is also the same as the nor-mal operation.E In the AMP test mode using main units keys, the keysbelow provide a special operation according to the posi-tion where the selector is set.

SERIAL TEST MODE(1) Setting the serial test mode The unit is put into the serial test mode when a serial codeTEST ON is input during the POWER-ON sequence.In the 16-bit serial test mode, serial code C27FH is input.EIn the serial test mode, all remote control keys and ordi-nary serial codes are disabled. Only the panel keys per-form the same operation as usually.(2) Canceling the serial test modeEThe serial test mode is canceled to return to the ordinarymode by inputting a TEST OFF code (C27 EH). Afterthe ordinary mode was returned, the serial mode isreturned to the state before the test mode is entered.The backup operation is not initialized.EThe serial test mode is also canceled when the AC poweris turned OFF.(3) CautionsEThe serial test code is prescribed as a 16-bit code only.EThe operations below are inhibited in the serial test mode. The operations mentioned above cannot be guaranteedwhen they are performed in the serial test mode.E An identical code is output when the serial test modecode is input.(6) When selector is set to positions other than TUNERENTER key Every time this key is pressed, master VOL-UME level is selected cyclically.INITIALIZE level MAX MID MIN Value of MasterVOLUMEPress the ENTER key.Press the PURE A key, then press the ENTER key.MAX8616.00MID408.00MIN10.20INITIALIZE71.40R-SE9(K) 1P 97.11.29 3:34 AM yW 7R-SE95ADJUSTMENTNO.ITEMINPUTSETTINGSOUTPUTSETTINGSTUNERSETTINGSALIGNMENTPOINTSALIGN FORFIG.1DISCRIMINATOR(A)98.0kHz1kHz, 75kHz dev.60dB(ANT input)Connect a DCvoltmeterbetweenPin 1 and Pin 2of CN 2.MONO98.0MHzL 310V(a)L 32Minimum distortion.2DISTORTION(STEREO)(C)98.0MHZ1kHz, 68.25kHz dev.Pilot: 6.75kHz dev.60dB(ANT input)(B)AUTO98.0MHzIFT (A1)Minimum distortion.(a)NO.ITEMINPUTSETTINGSOUTPUTSETTINGSAMP SETTINGSALIGNMENT POINTSALIGN FORFIG.POWER: ON1A CLASSB CLASSIDLE CURRENTConnect a DCvoltmeteracrossCN9(L)CN10(R)(X09, A/4)PURE A : ONPURE A : OFFVolume : 0VR1(L)VR2(R)(X09, A/4)18mV(b)2A CLASSIDLE CURRENTEXCEPT TUNERPURE A : ONVolume : 0.2010.00Less than 90mV.(Check)3A CLASSIDLE CURRENTEXCEPT TUNERPURE A : ONVolume : 10.2016.00Less than 250mV.(Check)SYSTEMCONTROLANTENNAAMGNDFM75CDININRECPLAYSUPERWOOFERPRE OUTSPEAKERS( 6 - 16 )LRTAPERECPLAYMDAUXRLOscilloscopeDistortion meterAC voltmeterDummy antenna(A)(B)(C)(D)AGAGFM SGMPXAGFM SGAM SG(a)(b)CN9(L)CN10(R)Dc voltmeter18mVFM SECTIONX05-4622-71 (T TYPE)AUDIO SECTION (X09-470 x-xx)SYSTEM CONNECTIONSR-SE9(K) 1P 97.11.29 3:34 AM yW 10ABDCE2135746Refer to the schematic diagram for the value of resistors and capacitors.PC BOARD(Component side view)TUNER UNIT (X05-4600-72) : M(X05-4622-71) : T6R-SE9(K) 1P 97.11.29 3:34 AM yW 9FHJLNGIKMO2135746Refer to the schematic diagram for the value of resistors and capacitors.PC BOARD(Component side view)78AUDIO UNIT(X09-4700-21) : M(X09-4702-71) : TDISPLAY UNIT(X14-4560-21) : M(X14-4562-71) : TR-SE9(K) 2P 97.11.29 3:17 AM y W 2ABDFHJCEGI2135746-B LINE+B LINEIC1IC2TUNER UNIT (X05-4600-72) : MAMIFTOSCRF:D3,4: 2SC4116(Y,GR) orQ52SC4177(C5,C6)D4UZ-5.1BSBMTZJ5.1(B)orICFM 300D8SWFM/AMICSYSTEMFM/AMQ5FMD10MA111HSS1042SA1611(M5,M6)Q3PLLD3:IC4NJM4565MD2D1Q1FM IFAMPLC72131LA1832:IC2IC12SC2714(R.O):Q1Q3:D1,2,81SS133 or 2SA1586(Y,GR) orAM ANTGNDFM 75J1J2+12V+12V-B+BSIGNAL LINEGND LINE+5V+5V+5V+5V+5V+5V+5V+5V+5V+5V+5V+B+B+B+B+B+B+B+B+B+B+B+B+12V+12V+5V+5V+5V+5V+12V+12V+12V+12V+12V0V(0.6V)VT VOLTAGELF:LOW FREQUENCYHF:HIGH FREQUENCYVT VOLTAGE4.7V1.2V4.1V1.7VHFLFHFLFFREQ.AMFMBAND0.2V(1.9V)13.1V12.9V(0V)12.1V0V(10.4V)2.5V(0V)ST:4.0VMONO:0V5.1V0V0V0V2.5V0V0V1.0V1.0V4.4V2.5V5.1V2.1V11.2V1.3V5.1V5.1V5.2V2.1V2.1V2.1V(3.8V)(1.3V)4.0V(0V)2.1V(1.0V)(3.0V)5.2V3.7V1000PC722PC631KR40C40.014.7u25C19R14 7.5K1W+C2510u16R411801KR20C5247PUNTUNE:4.9V2.5VST:0VMONO:4.7V3.2V0V4.0V2.5V(2.0V)2.4V5.2V(2.1V)1.8V(2.1V)1.3VMONO:2.7VST:4.2V2.5V(0V)FM:11.0VTUNE:0V+12VR301K1/4WC3 4PR46100K12348.2KR19C231u50+X2456KHz47KR1347KR7C21C225600PC171000PC1810u16+C16LOWCUTPILOTSMETEROSCBUFFSWDET15KR47C131000P+C141u50C1522P47KR483KR18+C122.2u501u50C11+CF310.7MHz270R17L2R441000.01C810117896453121213141516171819202221R25100L41uH0.011000P47u1010K1K2.2K1000P100P2.2u50+1/4WR26560R245.6KR70C29R321.2K12KR33C32C31C35R28R291KC34C33R31 10K6R27R22R231K1KC38R211K470P7.2MHzX1C3722PC3627P543+100u16C30+2423222019171618211415131OSCFMSDADJ2AMMIXFMIFAFC3REGAMRF5AMIFAM6SDGNDAMAGCDETOUT8STEREOMPXIN9VCCFMDETMPXVCO74RIFCOUNTDETLFM/AMPHASE121110+C9 10u16C10 0.047AMIFOUTC200.1ONRESET12bits PROGRAMABLEDIVIDERSWALLOW COUNTER1/16,1/17 4bitsUNIVERSAL COUNTER2DATA SHIFT REGISTER LATCHC B I/FDETECTORUNLOCKCHARGE PUMPPHASE DETECTORDIVIDERREFERENCER8330L31uHL1330100R63.3KR55.60.01C1R30.01CF1R4330R21/2POWER680C2R1CF2R45220R431/4W10KC27+821/4W1u50C2647u16R42()()()C18C124.7KR6C9100P2GND12PR11330.01C172PC11L60.0133PC1322PC14R91.8KC156P867ANT1ANT2GND56PC19C21L1L724PC112PC200J410K1200P2.2uHL20.01C26C4R5100KL33PC2R233R3R4 330KL4C24C64PL5J3C7R7100K0.01R8560P0C16180J2 0C8180R100J118PT1 47P1OSCIF-OUT2VCC30.01VT4A1 (W02-2608-05)TR4:2SC2413K or 2SC2778:2SK360:1SV225 or HVM16D13TR24TR1TR3TR1FM FRONT ENDD1TR2XXXXCAUTION: For continued safety, replace safety critical components only with manu-facturers recommended parts (refer to parts list). indicates safety critical compo-nents.
