Components identified with the IEC symbolin the parts list are special significance to safety. When replacing a component identified with , use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably insulated from the supply circuit before retuming the product to the customer. Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge build-up or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static can generate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.) 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices. CAUTION : harman/kardonAVR137/230 Service Manual Page 2 of 87 RadioFans.CN 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 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 o.5mA. 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. Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) AC Leakage Test Leakage current tester Reading should not be above 0.5mA Earth ground harman/kardonAVR137/230 Service Manual Page 3 of 87 RadioFans.CN ENGLISH TECHNICAL SPECIFICATIONS 35 Technical Specifications Audio Section Stereo Mode Continuous Average Power (FTC) 40 Watts per channel, 20Hz20kHz, < 0.07% THD, both channels driven into 8 ohms Five-Channel Surround Modes Power Per Individual Channel Front L Amplifier is in protection mode Check speaker-wire connections for shorts at receiver light around Power switch1is reddue to possible shortand speaker ends Amplifier is in protection mode Contact your local Harman Kardon service depot due to internal problems No sound from surround or Incorrect surround mode Select a mode other than Stereo center speakers Incorrect configuration Check speaker mode Stereo or Mono program material With (analog or digital) Dolby surround modes, the surround decoder may not create rear-channel information from non-encoded programs Speakers not properly connected Check speaker-wire connections or use test tone to verify connections (see page 20) Unit does not respond to Weak batteries in remote Change remote batteries remote commands Wrong device selected Press the AVR selector 5 Remote sensorEis obscured Make certain front-panel sensor is visible to remote or connect remote sensor Intermittent buzzing in tuner Local interference Move unit or antenna away from computers, fluorescent lights, motors or other electrical appliances Letters flash in the Channel Indicator Digital audio feed paused Resume play for DVD Display ?and Digital Audio stops Check that Digital Signal is fed to the Digital Input selected 32995_AVR137_ENG 16/05/07 12:29 Side 34 harman/kardon AVR137/230 Service Manual Page 5 of 87 RadioFans.CN NO DE S C R I PTI ON PA R TS NO.Q , t y 1 2 3 4 5 1 A C C E S S OR Y - 1 BOX , OU T C A R TON5 6 1 3 DE S C R I PTI ONNO C PS 4A 564 C Q X A V R 132/ 230 C PG 1A 8 20T 1 1 1 Q , t yPA R TS NO.
