14、acement Parts List -103 RadioFans.CN 收音机爱 好者资料库 3 1Safety Precautions 1.1.General Guidelines 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the prote

15、ctive devices such as insulation barriers, insulation papers shields are properly installed. 3. After servicing, carry out the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.1.1.Leakage Current Cold Check 1. Unplug the AC cord and connect a jumper bet

16、ween 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 metallic part has a return path to the chassis, the reading sh

17、ould 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 this check. 2. Connect a 1.5k, 10 watts resistor, in parallel

18、 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. 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure

19、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 used to make the hot checks, leakage current must not exceed

20、 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. Figure. 1 RadioFans.CN 收音机爱 好者资料库 4 1.2.Caution for AC Cord 5 1.3.Before Repair and Adjustment

21、Disconnect AC power, discharge unit AC Capacitors as such C702, C710, C725, C727 and C728 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 are completed, restore power gradua

22、lly using a variac, to avoid overcurrent. Current consumption at AC 220 - 240V, at 50Hz in NO SIGNAL mode (at volume min in FM Tuner mode) should be 200 mA. 1.4.Caution For Fuse Replacement 1.5.Protection Circuitry The protection circuitry may have operated if either of the following conditions are

23、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 rat

24、ed 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

25、the power is first turned off and then on again. 1.6.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 List. It is essential that these

26、critical parts should be replaced with manufacturers specified parts to prevent shock, fire or other hazards. Do not modify the original design without permission of manufacturer.

Such components commonly are

30、called Elec- trostatically 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 electrostatic discharge

31、(ESD). 1. Immediately before handling any semiconductor component or semiconductor-equiped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reaso

32、ns prior to applying power to the unit under test. 2. After removing an electrical assembly equiped with ES devices, place the assembly on a conductive surface such as alumin- ium foil, to prevent electrostatic charge build up or exposure of the assembly. 3. Use only a grounded-tip soldering iron to

33、 solder or unsolder ES devices. 4. Use only an anti-static solder remover device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges

34、 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, aluminium foil or compara- ble conductiv

35、e 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 ot

36、her 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 lifting of your foot from a carpeted floor can generate static electricity (ESD) suf- ficient to damage an ES dev

37、ice). 7 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) Maximum output radiation power from pickup: 100 W/VDE Laser radiation from the pickup unit is safety level, b

38、ut 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

39、lens for a long time. ACHTUNG : Dieses Produkt enthlt eine Laserdiode. Im eingeschalteten Zustand wird unsichtbare Laserstrahlung von der Lasereinheitadg- estrahit.
