I Le norme di sicurezza esigono che lapparecchio venga rimesso nelle condizioni originali e che siano utilizzati i pezzi di ricambio identici a quelli specificati. After servicing and before returning set to customer perform a leakage current measurement test from all exposed metal parts to earth ground to assure no shock hazard exist. The leakage current must not exceed 0.5mA. CLASS 1 LASER PRODUCT 3122 110 03420 GBWarning ! Invisible laser radiation when open. Avoid direct exposure to beam. SVarning !

Use an AC voltmeter, having 5000 per volt or more sensitivity. Connect a 1500 10W resistor,paralleled by a 0.15uF 150V AC capacitor between a knomn good earth ground (water pipe, conduit, etc.) and all exposed metal parts of cabinet (antennas, handle bracket, metal cabinet screwheads, metal overlays, control shafts, etc.). SAFTY PRECAUTIONS LEAKAGE CURRENT CHECK Measure the AC voltage across the 1500 resistor. The test must be conducted with the AC switch on and then repeated with the AC switch off. The AC voltage indicated by the meter may not exceed 0.3V.A reading exceeding 0.3V indicates that a dangerous potential exists, the fault must be located and corrected. Repeat the above test with the DVD VIDEO PLAYER power plug reversed. NEVER RETURN A DVD VIDEO PLAYER TO THE CUSTOMER WITHOUT TAKING NECESSARY CORRECTIVE ACTION. READING SHOULD NOT EXCEED 0.3V DVD VIDEO PLAYER AC OUTLET AC VOLTMETER Test all exposed metal. Voltmeter Hook-up for Leakage Current Check 0.15uF 150V AC 1500 10W (5000 per volt or more sensitivity) Good earth ground such as a water pipe, conduit, etc. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated dangerous voltage within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 2-3 3-13-1 BLOCK DIAGRAM 4-14-1 WIRING DIAGRAM CN1 J6 J1 J7 J8 J9 J13 CON1 CN1 CN1 J2 CN702 CN302 MAIN BOARD Alt and Bass Divider BOARD Alt and Bass Divider BOARD POWER BOARD AC Socket & Aux Jack Board KEY BOARD IR BOARD CONNECT BOARD iPod BOARD CN701 CN301 CN302 CN303 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 6-16-1 CIRCUIT DIAGRAM-MAIN BOARD AND KEY BOARD PART 1 6-26-2 CIRCUIT DIAGRAM-MAIN BOARD PART2 6-36-3 CIRCUIT DIAGRAM-MAIN BOARD&iPod DOCKING BOARD PART3 6-46-4 LAYOUT DIAGRAM-MAIN BOARD 6-56-5 LAYOUT DIAGRAM-KEY BOARD 6-66-6 LAYOUT DIAGRAM-iPod BOARD/AC SOCKET&AUX JACK BOARD/CONNECT BOARD/IR BOARD IR BOARD CONNECT BOARD AC SOCKET&AUX JACK BOARDiPod BOARD 7-17-1 CIRCUIT DIAGRAM-POWER BOARD 1 2 CN1 F1 T3.25AL250VAC CX1 224/275V LF1 CX2 224/275V R64 R65 R66 R67 LF2 CY1 BD1 EC1 68UF/400V EC1A 68UF/400V R3 R4 R5R5A R8 R9 R11 R16AR16 R18 R20 R75 R22R23 R25 R27 R30 R31 R33 R34 R32R35 R43 R40 R39 C1 C2 C3 C4 C5 C7 C8 C9 C10 C11 C12A C15 D1 D8 D5 D6 D7 D10 D9 D20 Q3 Q2 EC3 P3A PC817 P3B PC817 EC6 T4 T3 T6 EC11 EC7 EC9 EC8 EC4 EC5 EC15EC16EC13EC14 L1 U2 TL431 U3TL431 ECO STB S7.5V +5.2V Z2 NC Z1 P2A PC817 P2B PC817 R42 R68-726PCS R44 R45 R54 R48 R69 R52-R52A/B/C4PCS R57 R56R55 R58 R59R60 D11 L3 HCC P1A PC817 P1B PC817 +27V PGND C14 EC12 L2 EC10 T R1 T R2 1 2 4 8 3 6 7 5 IC1TP219B U3 TL431 R77 R63 R74 T5 T8 RT1 5D-13 VT1 10D-471 EC2 22UF/400V 1 4 2 3 5 CY2 HCC 2 4 C1A OUT 5 GND 4 NC 7 COMP 2 HV 8 RT 1 CS 3 VCC 6 IC2 7 8 6 10 R65 C12 R61 R62 C13 R41 R22A 7 8 9 10 L4EC17EC18 L5 Primary Secondary 7-27-2 LAYOUT DIAGRAM-POWER BOARD TOP SIDE 7-37-3 LAYOUT DIAGRAM-POWER BOARD BOTTOM SIDE 8-18-1 EXPLODED VIEW
