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 replacementparts 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 queles pices de remplacement doivent avoir la mme dsignation.ANY MEASUREMENTS NOT WITHIN THELIMITS OUTLINED ABOVE ARE INDICATIVEOF A POTENTIAL SHOCK HAZARD ANDMUST BE CORRECTED BEFORE RETURN-ING THE APPLIANCE TO THE CUSTOMER.2. PRODUCT SAFETY NOTICEMany electrical and mechanical parts in the appliancehave special safety related characteristics. These areoften not evident from visual inspection nor theprotection afforded by them necessarily can be obtainedby using replacement components rated for voltage,wattage, etc. Replacement parts which have thesespecial safety characteristics are identified in thisService Manual.Electrical components having such features areidentified by marking with a on the schematics andon the parts list in this Service Manual.The use of a substitute replacement component whichdoes not have the same safety characteristics as thePIONEER recommended replacement one, shown in theparts list in this Service Manual, may create shock, fire,or other hazards.Product Safety is continuously under review and newinstructions are issued from time to time. For the latestinformation, always consult the current PIONEERService Manual.

SAFETY PRECAUTIONSThe following check should be performed for thecontinued protection of the customer and servicetechnician.LEAKAGE CURRENT CHECKMeasure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakagecurrent tester such as Simpson Model 229-2 orequivalent between the earth ground and all exposedmetal parts of the appliance (input/output terminals,screwheads, metal overlays, control shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on. Anycurrent measured must not exceed 0.5 mA.DeviceundertestLeakagecurrenttesterEarthgroundReading shouldnot be above0.5 mAAlso test withplug reversed(Using AC adapterplug as required)Test allexposed metalsurfacesAC Leakage TestRadioFans.CN 收音机爱 好者资料库 VSX-417-K356785678CDFABEImportant 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.

(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.0 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.
