30、SAFETY NOTICE Many 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

31、parts which have thesespecial safety characteristics are identified in this ServiceManual. Electrical components having such features are identifiedby marking with a on the schematics and on the partslist in this Service Manual.The use of a substitute replacement component which doesnot have the sam

32、e safety characteristics as the MARANTZrecommended replacement one, shown in the parts list inthis Service Manual, may create shock, fire, or otherhazards. Product Safety is continuously under review and newinstructions are issued from time to time. For the latestinformation, always consult the curr

SAFETY PRECAUTIONS The following check should be performed for thecontinued protection of the customer and servicetechnician.LEAKAGE CURRENT CHECK Measure l

34、eakage current to a known earth ground (waterpipe, conduit, etc.) by connecting a leakage current testersuch as Simpson Model 229-2 or equivalent between theearth ground and all exposed metal parts of the appliance(input/output terminals, screwheads, metal overlays,control shaft, etc.). Plug the AC

35、line cord of the appliancedirectly into a 120V AC 60Hz outlet and turn the AC powerswitch on. Any current measured must not exceed 0.5mA.(FOR USA MODEL ONLY)LeakagecurrenttesterReading shouldnot be above0.5mADeviceundertestTest allexposed metalsurfacesAlso test withplug reversed(Using AC adapterplug

SERVICING PRECAUTIONSCAUTION : Before servicing the DVD covered by this servicedata and its supplements and ADDENDUMS, read and followthe SAFETY PRECAUTIONS. NOTE : if unforeseencircumstances create conflict between the following servicingprecautions and an

37、y of the safety precautions in thispublications, always follow the safety precautions.Remember Safety First:General Servicing Precautions1. Always unplug the DVD AC power cord from the ACpower source before:(1) Removing or reinstalling any component, circuit board,module, or any other assembly.(2) D

38、isconnection or reconnecting any internal electricalplug or other electrical connection.(3) Connecting a test substitute in parallel with an elec-trolytic capacitor.Caution : A wrong part substitution or incorrectpolarity installation of electrolytic capacitors may resultin an explosion hazard.2. Do

39、 not spray chemicals on or near this DVD or any ofits assemblies.3. Unless specified otherwise in this service data, cleanelectrical contacts by applying an appropriate contactcleaning solution to the contacts with a pipe cleaner,cotton-tipped swab, or comparable soft applicator.Unless specified oth

40、erwise in this service data, lubricationof contacts is not required.4. Do not defeat any plug/socket B+ voltage interlocks withwhich instruments covered by this service manual mightbe equipped.5. Do not apply AC power to this DVD and/or any of itselectrical assemblies unless all solid-state device h

41、eatsinks are correctly installed.6. Always connect test instrument ground lead to theappropriate ground before connection the test instrumentpositive lead. Always remove the test instrument groundlead last.Insulation Checking ProcedureDisconnect the attachment plug from the AC outlet and turnthe pow

42、er on. Connect an insulation resistance meter(500V)to the blades of the attachment plug. The insulation resistancebetween each blade of the attachment plug and accessibleconductive parts (Note 1) should be more than 1M-ohm.Note 1 : Accessible Conductive Parts including Metal panels,Input terminals,

43、Earphone jacks, etc.Electrostatically Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damagedeasily by static electricity. Such components commonly arecalled Electrostatically Sensitive (ES) Devices. Examples oftypical ES devices are integrated circuits and some field effecttra

44、nsistors and semiconductor chip components.The following techniques should be used to help reduce theincidence of component damage caused by static electricity.1. Immediately before handling any semiconductor compo-nent or semiconductor-equipped assembly, drain off anyelectrostatic charge on your bo

45、dy by touching a knownearth ground. Alternatively, obtain and wear a commer-cially available discharging wrist strap device, whichshould be removed for potential shock reasons prior toapplying power to the unit under test.2. After removing an electrical assembly equipped with ESdevices, place the as

46、sembly on a conductive surface suchas aluminum foil, to prevent electrostatic charge buildup orexposure of the assembly.3. Use only a GROUNDED-tip soldering iron to solder orunsolder ES devices.4. Use only an anti-static solder removal device. Somesolder removal devices not classified a “anti-static

47、” cangenerate electrical charges sufficient to damage ESdevices.5. Do not use freon-propelled chemicals. These cangenerate electrical charge sufficient to damage ESdevices.6. Do not remove a replacement ES device from its protec-tive package until immediately before you are ready toinstall it. (Most

48、 replacement ES devices are packaged withleads electrically shorted together by conductive foam,aluminum foil, or comparable conductive material).7. Immediately before removing the protective material fromthe leads of a replacement ES device, touch the protectivematerial to the chassis or circuit as

49、sembly into which thedevice will be installed.Caution : Be sure no power is applied to the chassis orcircuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Normally harmless motion suchas the brushing together of your clothes fab

50、ric or the liftingof your foot from a carpeted floor can generate static elec-tricity sufficient to damage an ES device.)44.
