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-A550MD 1 FM Antenna ADH7004 2 Operating Instructions See Contrast table (2) (English/French) 3 AM Loop Antenna XTB3001 4 Remote Control Unit XZN3046 (CU-XR054) 5 Battery Cover AZA7204 NSP 6 Dry Cell Battery (R6P, AA) VEM-013 7 Catalog Bag Z21-038 (0.03 × 230 × 340) 8 Front Pad XHA3003 (1) PACKING PARTS LIST 9 Rear Pad XHA3004 10 Packing Case See Contrast table (2) 11 Packing Sheet AHG7049 NSP 12 Warranty Card See Contrast table (2) 13 Power Cord See Contrast table (2) NSP 14 Polyethylene Bag AHG7033 15 Operating Instructions See Contrast table (2) (Chinese/portuguese) 16 Operating Instructions See Contrast table (2) (English/Spanish) 2.1 PACKING Mark No. Description Part No. 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 6 1 3 7 8(1/2) 11 9(1/2) 13 2 15 DBDXJ Type Only KUCXJ Type Only KUCXJ Type Only 16 12 4 9(2/2) 10 8(2/2) 5 14 2.

"K" means 1000Ω, and "M" means 1000kΩ. • Capacitors unless otherwise specified are in µF. "P" is an abbreviation for pF. • Capacitors indicated as (CH), (RH), (TH), (UJ), (CK), etc. are ceramic tempetature compensation types. Capacitors indicated as (ML) are Mylar type. • For electrolytic capacitors, indication is in the order of capacity and voltage resistance. • Parts indicated with the mark ( mark) are important for safety reasons.

PCB PARTS LIST NOTES: •Parts marked by "NSP" and can not be supplied. •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 ......................................................
