Check that the rear of the product indicates the correct supply voltage for your area. 2. The lighting flash with the arrowhead within an equilateral triangle is intended to alert the user or service agent to the presence of dangerous voltages within the product enclosure that may be of sufficient magnitude to constitute a risk of electric shockto persons. 3. The exclamation point within an equilateral triangle is intendedto alert the user or service agent to the presence of important operating and maintenance (Servicing) instructions in the literatureaccompanying the appliance. 4. This product complies with EEC Low Voltage (73/23/EEC) and Electromagnetic Compatibility (89/336/EEC) Directives when used and serviced in accordance with this manual. For continued compliance all components marked safety and EMC critical must only be replaced by Cambridge Audio approved parts.5. Any unauthorised design alterations or additions will void the manufacturerswarranty; furthermore the manufacturer cannot accept responsibility for personal injury or property damage resulting therefrom. 6. When servicing, care should be taken to observe the original routing anddressing of the leads and it should be confirmed that they have been returned to normal after re-assembly.Notes on chip component replacementNever reuse a component that has been removed from a PCB Notice that the minus side of a tantalum capacitor may be damaged by heat COPYRIGHT NOTICE. 2006 Audio Partnership PLC.

Use of controls or adjustments, or performance of procedures other than those specified within the service or instruction manual may result in hazardous radiation exposure. WARNING!WARNING!1. Service should only be performed by qualified personnel. 2. This equipment has been designed and manufactured to meet international safety standards; it is the legal responsibility of the repairer to ensure that these safety standards are maintained. 3. Any repairs must be made in accordance with the relevant safety standards.4. It is essential that safety and EMC critical components are replaced with Cambridge Azur approved parts only.CLASS 1 LASER PRODUCTNOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concerated so as to be focused on the disc reflective surface bythe objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30cm away from the objective lens. 45Cambridge Audio Azur 640C V2 CD PlayerAP175163 Front Panel PCB SchematicSW1PLAY/PAUSESW2STOPSW3OPEN/CLOSE12CN1CONN-H2SEG1116SEG1015SEG914SEG813SEG712SEG611SEG510SEG49SEG38SEG27SEG16SEG05COM34COM23COM12COM01SEG1217SEG1318SEG1419SEG1520SEG1621SEG1722SEG1823LCD1LCDPACKAGE=LCD D60012345678CN2CONN-H812345678CN3CONN-H81234567CN4CONN-H7R327KR433KR52K7R610KR782KR81K5R982KC1100n 50V X7R+5VC21n 50V X7RC31n 50V X7RR1068KR113K3+5VFORWARD SKIPFORWARD SEARCHBACKWARD SKIPBACKWARD SEARCHSW4SW-TACTSW5SW-TACTC4100n 50V X7RR15100RVSS14RB211RC46RC28RC37RB112RB4/OSC2/CLKOUT3RB013VDD1RB5/OSC1/CLKIN2RB3/MCLR/VPP4RC5/TOCKI5RC19RC010U3PIC16C505SW6SW-TACTP1PADP2PADR124K7R1310KQ2BC327+5V123CN5CONN-H3123CN6CONN-H31234567CN7CONN-H7C610uF 10V ELR14220RQ1BC337K1K2+5VPWR DETRESETR1220RR175K6R182K2+5VQ4BC337R194K712CN8MCLK_LOCKC510U 16V ELR25K6R2082RR164k7+5VD11N58192CCW1CW3R21100RD2LED 3MM BLUE+5V3OPT1GND2U2IR REC 3/5V 36KHZQ3BC337R2210kTo enhance viewing, please print to A36Cambridge Audio Azur 640C V2 CD PlayerAP175164 Front Panel PCB Layout (Top Side)To enhance viewing, please print to A37Cambridge Audio Azur 640C V2 CD PlayerAP175164 Front Panel PCB Layout (Bottom Side)To enhance viewing, please print to A38AP17519/2AP PART NOVALUEDESCRIPTIONQTYCOMPONENTIDENTFACTORY PART NONOTESRESISTORS82R0.25W 1% Metal Film Resistor1R201011-002014-000100R0.25W 1% Metal Film Resistor2R151011-001014-000220R0.25W 1% Metal Film Resistor2R1, 141012-201014-0001K50.25W 1% Metal Film Resistor1R81011-502014-0002K20.25W 1% Metal Film Resistor1R182K70.25W 1% Metal Film Resistor1R51012-702014-0003K30.25W 1% Metal Film Resistor1R111013-302014-0004K70.25W 1% Metal Film Resistor3R12, 16, 191014-702014-0005K60.25W 1% Metal Film Resistor2R2, 1710K0.25W 1% Metal Film Resistor3R6, 13, 221011-003014-00027K0.25W 1% Metal Film Resistor1R31012-703014-00033K0.25W 1% Metal Film Resistor1R41013-303014-00068K0.25W 1% Metal Film Resistor1R101016-803014-00082K0.25W 1% Metal Film Resistor2R7, 91018-203014-000100R Multi turn pot1R211nFCeramic 50V 10% 5mm pitch 2C2, 31100-102043-000100nCeramic 50V X7R 10% 5mm pitch 2C1, 410uF 25VRadial Electrolytic, 20%, 1C5, 61102-100024-000PY214BC337-25NPN small signal transistor TO-923Q1, 3, 41300-337000-100PY219BC327-25PNP small signal transistor TO-921Q21301-327000-100PY054TSOP1836SS3V IR Receiver module (VISHAY)1U23001-183600-001PIC16C505Microchip 14 pin 8 Bit PIC1U34116-505054-200Programmed with:AP18402/1 640CV2 V1.0.hexPD0121N5819Schottky diode1D1PY064Blue LED3mm Blue flat top LED1D23100-000030-003PY043Tact switchTACT SW 2P2T KPT-1105A (5MM)6SW1, 2, 3, 4, 5, 62400-020200-000PY936AP17522/1 Positive LCD for V2 1LCD13110-066350E000PY806LCD back light assembly16600-990095-000Cambridge Azur 640C V2 Front Panel PCB Assembly BOMMISCELLANEOUSSEMICONDUCTORSTRANSISTORSCAPACITORSNote: resistors, capacitors and other generic electronic components are not usally stocked by the manufacturer.
