DC balance adjustment (VR301)While observing the waveform with an oscilloscope at pin13 of IC301, adjust VR301 to minimize the waveform level.2. PLL control voltage adjustment (VC301)First set the transmission frequency to 87.9MHz with thecommander, then adjust VC301 so that the DC Voltage atthe +pole of C317, measured using a multi-meter or digitaltester, is +3V (±0.1V).NOTE: E type is 87.7MHz.3. Modulation level adjustment (VR303)The method uses a standard receiver or tuner.Adjust VR303 so that the output level from the standardreceiver or tuner is as specified.L.P.S initial position adjustment procedure1. Connect the changer to the H/U.2. While holding the magazine eject button of the changer,press the reset button of the H/U.3. After about 3 seconds, release the magazine eject button.4. Press the SRC button of the H/U to enter the CD-CH mode,and the H/U's display section indicates “E-88“.5. Move the mechanism deck to around the 1st stage bypressing the DISC- or DISC+ button.6. Insert the adjustment tool (W02-0635-00) into the tool holeon the changer mechanism.7. Then press the DISC+ button to move the mechanism deckuntil the mechanism's slider hits the adjustment tool.8. When the motor locks (stops), press the REPEAT key ofthe H/U.When the REPEAT key is pressed, the mechanism movesautomatically to the 1st stage and the initial positionadjustment completes. (The data is written in the EEPROMat this time.)W05-0635-00For KDC-CMP59FM9B CA D E243567110PC BOARD (Component side view)CD PLAYER UNIT (X32-5340-00)CP32W6R93R94R85R84R98X1X3X2CP28CP5R27R23C34C61C62C49R19R17R18C18C15C11R6C12R11 C22CP8C1C2C3C4R136377273108109 14418125251135412626505051517575767610010045R2CP18CP17CP16R69R66R67R68CP22CP21R78CP19CP20CP29R73R70W5C54R74R75R117R118R82R128R119R21C33C26R20C27R104R97R90CP13C70C75W2R48R122CP30R126R30W3R41CP26W4R36R96R95R28 R29R105R43R44R38R42R101W1C71R62R61C48C43C45C42R60C44R103R133R132C52R131C69R37 R39R106R45R31R13R32 C82EBBEBEBEBEBEBEBEEBCP4CP3CP2CP1R55R57R53R56R58R54R59BEGIOEBEBSO0TRDSPDS+B8VFODSLDSGNDDTCF+T-T+F-SP-SP+SL+SL-LchBU14VCHRSTCHCONCHMUTEREQCVRRchLOESW111920 3812316VREF LDCADBPDIOP+VCCIOP-EFSA3.3VSD-3.3VTE3TEFEARFRF EFMATESTSAGNDSDGNDRESETVPPSONMVDD/MSTOPT3DATA/CLKSW+3.3VRSTA+8VA+3VAGNDARMSWGNDT2BU+5VCOMMSWMIREJSWMGSWMILPONSCLSDADMUTEELV-8V/7VSVDDSPLO+SPLO-ELV+ELV-EEPWRT1VPPT2GNDRESETELVADJSCK0ADJSELSW+5V AVrefSRVSELNCTOFFHOT/CHCONSLNASSO0MTRMTLSI0GNDLPSELV+BUDETGNDBU+14VSRV8 PON5HCLKBU14 BU14BEEBD11D12IC1IC5IC2D6IC4Q6 Q8Q11Q10D3D2Q2Q24Q22IC11IC3D16D14CN1Q12Q15D13Q16Q17Q14Q19Q18IC12CN2X32-5340-00 (J74-1343-11)E BBEL.P.SQ9Q7Refer to the schematic diagram for the values of resistors and capacitors.(X32-5340-00)3D 4B 2A 4C 4D 5D 5B 5B 5D 5D 5DQ115DQ123BQ143BQ153BQ163BQ173BQ182CQ192CQ225BQ245BIC1 IC2 IC3 IC4 IC5 IC11 IC12 Q2 Q6 Q8 Q10Ref.
