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 MODLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pices de remplacement doivent avoir la mme dsignation. 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 RadioFans.CN 收音机爱 好者资料库 3 VSX-35TX, VSX-33TX 2.1 PACKING (1) PACKING PARTS LIST Mark No. Description Part No. 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. 1AM Loop AntennaATB7009 2FM Wire AntennaADH7004 3Operating InstructionsSee Contrast table (2) (English) 4Remote Control UnitSee Contrast table (2) NSP5Alkaline Dry Cell BatteryVEM1021 (LR6, AA) 6Front Pad 35AHA7287 7Rear Pad 35AHA7288 8Packing CaseSee Contrast table (2) 9Packing SheetAHG7010 NSP10Polyethylene BagZ21-038 (230 340 0.03) NSP11Warranty CardARY7007 12Battery CoverSee Contrast table (2) (2) CONTRAST TABLE VSX-35TX and VSX-33TX are constructed the same except for the following : MarkNo.Symbol and Description Part No. Remarks VSX-35TXVSX-33TX 3 4 4 8 8 12 Operating Instructions (English) Remote Control Unit (35TX) Remote Control Unit (33TX) Packing Case 35TX Packing Case 33TX Battery Cover ARB7222 AXD7266 Not used AHD7860 Not used AZN7841 ARB7223 Not used AXD7267 Not used AHD7861 AZN7826 1 2 3,11 10 12 9 5 4 6 7 8 FRONT 4 VSX-35TX, VSX-33TX 2.2 EXTERIOR SECTION C B F E B P N O Q R S J H I K L R T P Q V B T U F S V U O E M C D L A K D G A I H N G J 33 51 51 28 48 22 17 PCB Holder 22 48 48 12 36 47 47 47 47 47 47 47 31 37 47 40 47 45 47 47 47 47 47 35 34 44 47 47 47 47 47 49 47 47 47 29 25 47 45 47 46 45 47 38 15 21 Refer to 2.3 HEAT SINK SECTION. 47 23 4 6 11 19 14 13 50 50 18 20 5 2 or 3 51 47 Refer to 2.4 FRONT PANEL SECTION.
