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. CAUTION : 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. Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol in 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. 2 HK3480 harman/kardon Before returning the unit to the user, perform the following safety checks : 1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the unit. 2. Be sure that any protective devices such as nonmetallic control knobs, insulating fishpapers, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechanical insulators, etc. Which were removed for the servicing are properly re-installed. 3. Be sure that no shock hazard exists ; check for leakage current using Simpson Model 229 Leakage Tester, standard equipment item No. 21641, RCA Model WT540A or use alternate method as follows : Plug the power cord directly Into a 120 volt AC receptacle (do not use an Isolation Transformer for this test). Using two clip leads, connect a 1500 ohms, 10watt Resistor paralleled by a 0.15uF capacitor, in series with all exposed metal cabinet parts and a known earth ground, such as a water pipe or conduit. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure the AC voltage drop across the resistor. (See diagram) Move the resistor connection to each exposed metal part having a return path to the chassis (antenna, metal, cabinet, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor. (This test should be performed with the 0.35 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning the unit to the owner. 3 HK3480 harman/kardon HK 3480 TECHNICAL SPECIFICATIONS Audio Section Stereo Mode Continuous Average Power (FTC) 120 Watts per channel, 20Hz­20kHz @ < 0.07% THD, both channels driven into 8 ohms 150 Watts per channel, 20Hz­20kHz @ < 0.2% THD, both channels driven into 4 ohms Input Sensitivity/Impedance Linear (High Level) Signal-to-Noise Ratio (IHF-A) Frequency Response @ 1W (+0dB, ­3dB) High Instantaneous Current Capability (HCC) Transient Intermodulation Distortion (TIM) Rise Time Slew Rate 200mV/47k ohms 95dB 10Hz ­ 110kHz ±45 amps Unmeasurable 16µsec 40V/µsec FM Tuner Section Frequency Range Usable Sensitivity Signal-to-Noise Ratio Distortion Stereo Separation Selectivity Image Rejection IF Rejection Tuner Output Level AM Tuner Section Frequency Range Signal-to-Noise Ratio Usable Sensitivity Distortion Selectivity Video Section Television System Signal Format Input Level Input Impedance Sync Polarity Output Level Output Impedance Video Frequency Response General Power Requirement Power Consumption Dimension (Max) Width Height Depth Weight 87.5 ­ 108MHz IHF 1.12µV/13.5dBf Mono/Stereo 73/72dB Mono/Stereo 0.3/0.4% 40dB @ 1kHz ±400kHz, 65dB >80dB >100dB 1kHz, ±100kHz, Dev 500mV 520 ­ 1720kHz >40dB Loop 500µV/M 1kHz, 50% Mod 0.8% ±10kHz, >25dB Depth measurement includes knobs, buttons and terminal connections.

To correct this problem, first unplug the unit from the AC wall outlet and wait at least thirty minutes. After the pause, reconnect the AC power cord and check the unit's operation. If the system still malfunctions, a system reset may clear the problem. To reset the system, first turn the HK 3480 off by pressing the System Power Control. Next, press and hold the front-panel Mute Button for at least 4 seconds. The Main Information Display will briefly show the word RESET, and then return to normal operation. When the system is reset in this fashion, all tuner presets will be lost and must be reentered. If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor. If these steps do not solve the problem, consult an authorized Harman Kardon service center. 12 TROUBLESHOOTING GUIDE 17 HK3480 harman/kardon 13 HK3480 harman/kardon harman/kardon Service bulletin # H/K2003-10 December 2003 To: All harman/kardon Service Centers Models: AVR130, AVR230, AVR330, HK3380, HK3480 Subject: Volume Level Changes Service Bulletin Warranty labor rate: MAJOR repair On early versions of the AVR130,AVR230,AVR330,HK3380,HK3480, when the volume control is turned, the volume level and display may be erratic, and not track accurately, or the level may progress in an unintended direction. This may happen on a random basis and depends on where the volume control knob is positioned after a volume adjustment. During a running production change, new volume encoders were installed. In the event you receive an AVR model listed above with the complaint "The volume control on my receiver does not track accurately when turned", perform the following procedure: REPLACE VR74 (AVR130/230/330) or VR81 (HK3380/3480) VOLUME ENCODER Note: It is important that the various screws do not get mixed up and inserted in other locations upon reassembly. Make note or label each removed screw set; keep them apart from other screw sets. 1) Remove the top cover, (13) Phillips screws. 2) Remove the volume, bass, treble and balance knobs by pulling them straight out and off. If a tool is necessary for removal of the smaller knobs, make sure the jaws are insulated to avoid knob damage. 3) Remove the (10) Phillips screws holding the front panel ass'y to the chassis: (6) at the bottom and (4) at the sides. 4) Cut all plastic cable ties that would prevent you detaching the front panel ass'y from the chassis. Draw a diagram if necessary, for a location reminder, to aid reassembly. 5) Unplug connector CN15 (6 cond) or CN89 (7 cond) at the left side of the unit. See below. 6) Remove single ground screw at the left side of the unit, near CN15 or CN89. (Black wire) 7) Unplug connector CN72 (32 cond) or CN81 (20 cond) on the DSP PCB, coming from the top of the front panel ass'y. See below. 8) There should now be enough slack in the connecting cables to lift and detach the front panel ass'y from the chassis. Pull the front panel as far away as the remaining connecting wires will allow, enough to tilt and gain access to the rear of the Tone/Volume PCB. See illustration Page 2. 9) Remove the (10) screws or (9) screws holding the Tone/Volume PCB to the front panel. 10) Detach and pull back the PCB; unplug top connector CN84 (7 cond) or CN83 (4 cond) if necessary. 11) Remove and replace VR74 or VR81 (5 soldered pads) with hk part# HSR2A029Z. 12) Reassemble in reverse order, taking care to replace all connectors, cable ties, and ground screw. 13) Power up receiver, and test volume control to assure setting no longer changes settings by itself, or when the volume knob is tapped. 14 HK3480 harman/kardon Model AVR130 Serial Number 120V AN0006-01000 to AN0006-13800 AN0006-13801 and above AN0007-01000 to AN0007-11400 AN0007-11401 and above AN0008-01000 to AN0008-08524 AN0008-08525 and above AN0015-01000 to AN0015-02728 AN0015-02729 and above AN0016-01000 to AN0016-01864 AN0016-01865 and above STATUS Volume control may not track accurately when turned; erratic operation Modified By Factory Volume control may not track accurately when turned; erratic operation Modified By Factory Volume control may not track accurately when turned; erratic operation Modified By Factory Volume control may not track accurately when turned; erratic operation Modified By Factory Volume control may not track accurately when turned; erratic operation Modified By Factory ACTION Change VR74 Rotary encoder NONE REQUIRED Change VR74 Rotary encoder NONE REQUIRED Change VR74 Rotary encoder NONE REQUIRED Change VR81 Rotary encoder NONE REQUIRED Change VR81 Rotary encoder NONE REQUIRED AVR130 AVR230 AVR230 AVR330 AVR330 HK3380 HK3380 HK3480 HK3480 15 HK3480 harman/kardon harman/kardon Service bulletin # H/K2004-02 April 2004 To: All harman/kardon Service Centers Model: HK3380/3480 Subject: Silence During Preset Scan - Upgrade Service Bulletin Warranty labor rate: MINOR repair In the event you receive an HK3380 or HK3480 stereo receiver with the complaint: "When the Preset Scan Function * is activated and the receiver cyles through the list of station presets, there is silence", the unit is in need of a software upgrade.
