3、lshouldbefollowedduringservicing. 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 designat

4、ed 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 electric

5、ity. 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 caus

6、ed 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 sho

7、uld 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

8、 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 genera

9、te 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 com

10、parable 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

11、 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 devi

LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by co

13、nnecting 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 m

14、easured 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

(See pages 1619 for more information on speaker setup and configuration.) 7 Surround Mode Group Selector: Press this button to select the top-level group of surround modes. Each press of the button will select t

20、he current mode in each of the major groupings (e.g., Dolby, DTS, Logic 7, DSP, Stereo). When the button is pressed so that the name of a mode in the desired surround-mode group appears in the on- screen display and in the Lower Display Line , press the Surround Mode Selector 8 to cycle through the

21、individual modes available. For example, press this button to select Dolby modes,and then press the Surround Mode Selector 8 to choose from the various mode options.

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 assy to the chassis: (6) at

24、 the bottom and (4) at the sides. 4) Cut all plastic cable ties that would prevent you detaching the front panel assy 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.

25、 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 assy. See below. 8) There should now be enough slack in the connecting cables to lift and detach th

See illustration Page 2. 9) Remove the (10) screws or (9) screws holding the Tone/Volume PCB to the front panel. 10)

27、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,
