15、ch are important for safety. These parts are marked by in the Schematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical parts should be replaced with manufacturers specified parts to prevent X-RADIATION, shock, fire, or other hazards. Do

16、 not modify the original design without permission of manufacturer. 2. An Isolation Transformer should always be used during the servicing of AC Adaptor whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents res

17、ulting in personal injury from electrical shocks. It will also protect AC Adaptor from being damaged by accidental shorting that may occur during servicing. 3. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the

18、 short circuit. 4. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. 5. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.1.1.Leakage Curren

19、t Cold Check 1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. measure the resistance value, with an ohmmeter between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed met

20、allic part has a return path to the chassis, the reading should be between 1M and 5.2M. When the exposed metal does not have a return path to the chas- sis, the reading must be 1.1.2.Leakage Current Hot Check 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for th

21、is check. 2. Connect a 1.5k, 10 watts resistor, in parallel with a 0.15F capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1-1. 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across th

22、e resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be

23、 used to make the hot checks, leakage current must not exceed 1/2 milliamp. In case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.

24、库 4 1.2.Before Repair and Adjustment Disconnect AC power to discharge AC Capacitors (C5700, C5701, C5702, C5705 and C5706) through a 10W, 1W resistor to ground. Caution : DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs ar

25、e completed, restore power gradually using a variac, to avoid overcurrent. Current consumption at AC 220V - 240V, at 50Hz in NO SIGNAL mode (at volume min in FM Tuner mode) should be 200 mA. 1.3.Protection Circuitry The protection circuitry may have operated if either of the following conditions are

26、 noticed: No sound is heard when the power is turned on. Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are shorted, or if speaker systems with an impedance less than the indicated ra

27、ted impedance of the amplifier are used. If this occurs, follow the procedure outlines below: 1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute. Note: When the protection circuitry functions, the unit will not operate unless

28、 the power is first turned off and then on again. 1.4.Caution For Fuse Replacement 1.5.Safety Part Information Safety Parts List: There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Exploded View & Replacement Parts

29、 List. It is essential that these critical parts should be replaced with manufacturers specified parts to prevent shock, fire or other hazards.

32、66ADTRANSFORMER 5 2Warning 2.1.Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensi- tive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. The following

33、 techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain a

34、nd wear a commercially available discharging ESD wrist strap, 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 alumi- num foil, to

35、prevent electrostatic charge buildup 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 (ESD protected)” can generate electrical charge s

36、ufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges 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

37、packaged with leads electrically shorted together by conductive foam, aluminum foil or compara- ble 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

38、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 of your clothes fabric or the lifti

39、ng of your foot from a carpeted floor can generate static electricity (ESD) suf- ficient to damage an ES device). 6 2.2.Precaution of Laser Diode Caution: This product utilizes a laser diode with the unit turned on, invisible laser radiation is emitted from the pickup lens. Wavelength: 790 nm (CD) M

40、aximum output radiation power from pickup: 100 W/VDE Laser radiation from the pickup unit is safety level, but be sure the followings: 1. Do not disassemble the pickup unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pickup unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pickup lens for a long time. ACHTUNG : Dieses Produkt enthlt eine Laserdiode. Im eingeschalteten
