19、AUTION : Bef ore servicing the A/ V Receiver covered by thisservice data and its supplements and addends, read and f ollow theSAFETY PRECAUTIONS. NOTE : if unf oreseen circumstancescreate conf lict between the f ollowing servicing precautions and anyof the saf ety precautions in this publication, al

20、ways f ollow the saf etyprecautions.Remember Safety First:General Servicing Precautions1. Always unplug the A/ V Receiver AC power cord f rom the ACpower source bef ore:(1) Removing or reinstalling any component, circuit board,module, or any other assembly.(2) Disconnecting or reconnecting any inter

21、nal electrical plug orother electrical connection.(3) Connecting a test substitute in parallel with an electrolyticcapacitor.Caution : A wrong part substitution or incorrect polarity installationof electrolytic capacitors may result in an explosion hazard.2. Do not spray chemicals on or near this A/

22、 V Receiver or any of itsassemblies.3. Unless specif ied otherwise in this service data, clean electricalcontacts by applying an appropriate contact cleaning solution tothe contacts with a pipe cleaner, cottontipped swab, orcomparable sof t applicator.Unless specif ied otherwise in this service data

23、, lubrication ofcontacts is not required.4. Do not def eat any plug/ socket B+ voltage interlocks with whichinstruments covered by this service manual might be equipped.5. Do not apply AC power to this A/ V Receiver and/ or any of itselectrical assemblies unless all solid-state device heat sinks are

24、correctly installed.6. Always connect test instrument ground lead to the appropriateground bef ore connecting the test instrument positive lead. Alwaysremove the test instrument ground lead last.Insulation Checking ProcedureDisconnect the attachment plug f rom the AC outlet and turn thepower on. Con

25、nect an insulation resistance meter(500V) to theblades of the attachment plug. The insulation resistance betweeneach blade of the attachment plug and accessible conductive parts(Note 1) should be more than 1M-ohm.Note 1 : Accessible Conductive Parts including Metal panels, Inputterminals, Earphone j

26、acks, etc.Electrostatically Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damaged easily bystatic electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical Esdevices are integrated circuits and some f ield ef f ect transisto

27、rs andsemiconductor chip components.The f ollowing techniques should be used to help reduce theincidence of component damage caused by static electricity.1. Immediately bef ore handling any semiconductor component orsemiconductor-equipped assembly, drain of f any electrostaticcharge on your body by

28、touching a known earth ground.Alternatively, obtain and wear a commercially availabledischarging wrist strap device, which should be removed f orpotential shock reasons prior to applying power to the unit undertest.2. Af ter removing an electrical assembly equipped with ES devices,place the assembly

29、 on a conductive surf ace such as aluminumf oil, to prevent electrostatic charge buildup or exposure of theassembly.3. Use only a grounded-tip soldering iron to solder or unsolder ESdevices.4. Use only an antistatic solder removal device. Some solderremoval devices not classif ied a “anti-static” ca

30、n generateelectrical charges suf f icient to damage ES devices.5. Do not use f reonpropelled chemicals. These can generateelectrical charge suf f icient to damage ES devices.6. Do not remove a replacement ES device f rom its protectivepackage until immediately bef ore you are ready to install it. (M

31、ostreplacement ES devices are packaged with leads electricallyshorted together by conductive f oam, aluminum f oil, orcomparable conductive material).7. lmmediately bef ore removing the protective material f rom theleads of a replacement ES device, touch the protective material tothe chassis or circ

32、uit assembly into which the device will beinstalled.Caution : Be sure no power is applied to the chassis or circuit, andobserve all other saf ety precautions.8. Minimize bodily motions when handing unpackaged replacementES devices. (Normally harmless motion such as the brushingtogether of your cloth

33、es f abric or the lif ting of your f oot f rom acarpeted f loor can generate static electricity suf f icient to damagean ES device.)1-6SPECIFICATIONSSYSTEM Output level 2.2V Frequency response (ref. 0dB 20Hz-20kHz) + 0.5dB Total harmonic distortion (ref. 1kHz) C515BEEC, C-C515BEEAH)Ref NOPART NUMBER
