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 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.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.

Health & Safety Code Section 25249.6 - Proposition 65NOTICE(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.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.RadioFans.CN 收音机爱 好者资料库CDJ-400356785678CDFABEIMPORTANTTHIS PIONEER APPARATUS CONTAINSLASER OF CLASS 1.SERVICING OPERATION OF THE APPARATUSSHOULD BE DONE BY A SPECIALLYINSTRUCTED PERSON.LASER DIODE CHARACTERISTICSMAXIMUM OUTPUT POWER: 5 mWWAVELENGTH: 780 785 nmWARNING !The AEL(accessible emission level) of the laser power output is less then CLASS 1but the laser component is capable of emitting radiation exceeding the limit forCLASS 1.A specially instructed person should do servicing operation of the apparatus. Additional Laser Caution* : Refer to page 24.for TLFXJfor WYXJ5 and KUCXJfor TLFXJ(DRW2308)(DRW2248)1. Laser Interlock Mechanism The position of the switch (S1801) for detecting loading completion is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism is not clamped and LPS1 signal is high level.) Thus, the interlock will no longer function if the switch is deliberately set to LPS1 terminal side. ( if LPS1 signal is low level ). In the test mode* the interlock mechanism will not function. Laser diode oscillation will continue, if pin 41 of TC94A15FG (IC502) on the MAIN Assy is connected to GND, or else the terminals of Q501 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.CDJ-400 WYXJ5 and KUCXJ : Types OnlyChassisLABEL CHECK Printed on the chassisPrinted on the chassisCDJ-400412341234CDFABEImportant Check Points for Good ServicingIn this manual, procedures that must be performed during repairs are marked with the below symbol.Please be sure to confirm and follow these procedures.1. Product safetyPlease conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safety instructions described in this manual.1 Use specified parts for repair.Use genuine parts. Be sure to use important parts for safety.2 Do not perform modifications without proper instructions.Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as radio/TV interference and foreign noise.3 Make sure the soldering of repaired locations is properly performed.When you solder while repairing, please be sure that there are no cold solder and other debris.Soldering should be finished with the proper quantity. (Refer to the example)4 Make sure the screws are tightly fastened.Please be sure that all screws are fastened, and that there are no loose screws.5 Make sure each connectors are correctly inserted.Please be sure that all connectors are inserted, and that there are no imperfect insertion.6 Make sure the wiring cables are set to their original state.Please replace the wiring and cables to the original state after repairs.In addition, be sure that there are no pinched wires, etc.7 Make sure screws and soldering scraps do not remain inside the product.Please check that neither solder debris nor screws remain inside the product.8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.Damaged power cords may lead to fire accidents, so please be sure that there are no damages.If you find a damaged power cord, please exchange it with a suitable one.9 There should be no spark traces or similar marks on the power plug.When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.a Safe environment should be secured during servicing.When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. AdjustmentsTo keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.Adjustments should be performed in accordance with the procedures/instructions described in this manual.4. CleaningFor parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.3. Lubricants, Glues, and Replacement partsUse grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied.5. Shipping mode and Shipping screwsTo protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual.CDJ-400556785678CDFABECONTENTS SAFETY INFORMATION .21. SERVICE PRECAUTIONS.61.1 NOTES ON SOLDERING.62.

SERVICE PRECAUTIONS1.1 NOTES ON SOLDERING For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.CDJ-400756785678CDFABE2.
