SAFETY INFORMATION This service manual is intended for qualified service technicians ; it is not meant for the casual do-it- yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 – Proposition 65 NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation. REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pièces de remplacement doivent avoir la même désignation. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. 1. SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA. (FOR USA MODEL ONLY) Leakage current tester Reading should not be above 0.5mA Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) Earth ground AC Leakage Test www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 3 XR-A670, XR-A370 Printed on the Rear Panel MYXJ Type MYXJ Type NVXJ Type LABEL CHECK (For MYXJ and NVXJ Types) Additional Laser Caution 1. Laser Interlock Mechanism The position of the switch (S9501) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S9501) is pressed physically. Thus, the interlock will no longer function if the switch (S9501) is released physically and deliberatery. The interlock also does not function in the test mode ∗. Laser diode oscillation will continue, if pin 1 of CXA1821M (IC8101) on the CD ASSY mounted on the $M Loading Mechanism assembly is connected to GND, or else the terminals of Q8101 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam. ∗ : Refer to page 66. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mW WAVELENGTH: 780 nm to 785 nm IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 4 XR-A670, XR-A370 2.1 PACKING 2. EXPLODED VIEWS AND PARTS LIST NOTES: • 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 the product are used for disassembly. 1 Power Cord See Contrast table (2) 2 FM Antenna See Contrast table (2) 3 AM Loop Antenna XTB3001 4 Remote Control Unit XZN3067 (CU-XR060) 5 Battery Cover XZN3065 NSP 6 Dry Cell Battery (R6P, AA) VEM-013 7 Packing Sheet AHG7049 8 Front Pad XHA3013 9 Rear Pad XHA3014 10 Packing Case See Contrast table (2) NSP 11 Warranty Card See Contrast table (2) 12 Polyethylene Bag Z21-038 (0.03 × 230 × 340) 13 Operating Instructions See Contrast table (2) (English/French) 14 Operating Instructions See Contrast table (2) (Italian/Dutch/German) 15 Operating Instructions See Contrast table (2) (Portuguese/Swedish/Spanish) 16 Sub Pad XHA3017 17 Fuse (T5A) See Contrast table (2) NSP 18 Polyethylene Bag See Contrast table (2) (1) PACKING PARTS LIST Mark No. Description Part No. VOL KARAOKE SFC DISC DISC DISC CLEAR STATION REMOTE CONTROL UNIT CU-XR025 MONO BAND PGM REPEAT RANDOM AUX P.BASS DISPLAY SLEEP POWER 2 3 12 16 17 8(1/2) 7 9(1/2) 18 1 1 13 11 14 XR-A670/MYXJ and XR-A370/MYXJ Only Except NVXJ Type NVXJ Type Only 15 4 9(2/2) 10 8(2/2) 5 6 (2) CONTRAST TABLE XR-A670/MYXJ, NVXJ, KUCXJ, XR-A370/MYXJ, NVXJ and KUCXJ are constructed the same except for the following : Mark No. Symbol and Description Part No. Remarks XR-A670 /MYXJ XR-A670 /NVXJ XR-A670 /KUCXJ XR-A370 /MYXJ XR-A370 /NVXJ XR-A370 /KUCXJ NSP NSP 1 2 10 11 13 14 15 17 18 Power Cord FM Antenna Packing Case Warranty Card Operating Instructions (English/French) Operating Instructions (Italian/Dutch/German) Operating Instructions (Portuguese/Swedish/Spanish) Fuse (T5A) Polyethylene Bag ADG1154 ADH7005 XHD3090 ARY7022 XRE3023 XRC3014 XRC3015 Not used Not used ADG1156 ADH7005 XHD3090 ARY7022 XRE3023 Not used Not used AEK7001 AHG7033 ADG7022 ADH7004 XHD3091 ARY7033 XRE3024 Not used Not used Not used Not used ADG1154 ADH7005 XHD3081 ARY7022 XRE3023 XRC3014 XRC3015 Not used Not used ADG1156 ADH7005 XHD3081 ARY7022 XRE3023 Not used Not used AEK7001 AHG7033 ADG7022 ADH7004 XHD3082 ARY7033 XRE3024 Not used Not used Not used Not used www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 5 XR-A670, XR-A370 B C D A A B C D E E F F Refer to "2.3 FRONT PANEL SECTION".

PCB PARTS LIST NOTES: •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. •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%). 560 Ω → 56 × 10 1 → 561 ........................................................ RD1/4PU 5 6 1 J 47k Ω → 47 × 10 3 → 473 ........................................................ RD1/4PU 4 7 3 J 0.5 Ω → R50 ..................................................................................... RN2H R 5 0 K 1 Ω → 1R0 ..................................................................................... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω → 562 × 10 1 → 5621 ......................................................
