20、tery x 2 RadioFans.CN 收音机爱 好者资料库 (No.YD072)1-3 SECTION 1 PRECAUTION 1.1Safety Precautions (1) This design of this product contains special hardware and many circuits and components specially for safety purpos- es. For continued protection, no changes should be made to the original design unless auth

21、orized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services should be per- formed by qualified personnel only. (2) Alterations of the design or circuitry of the product should not be made. Any design alterations of the product should no

22、t be made. Any design alterations or additions will void the manufacturers warranty and will further relieve the manufacture of responsibility for personal injury or property damage resulting therefrom. (3) Many electrical and mechanical parts in the products have special safety-related characterist

23、ics. These characteris- tics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by us- ing replacement components rated for higher voltage, watt- age, etc. Replacement parts which have these special safety characteristics are identified in th

24、e Parts List of Ser- vice Manual. Electrical components having such features are identified by shading on the schematics and by ( ) on the Parts List in the Service Manual. The use of a substitute replacement which does not have the same safety charac- teristics as the recommended replacement parts

25、shown in the Parts List of Service Manual may create shock, fire, or other hazards. (4) The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of el

26、ectric shock and fire hazard. When service is required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after reassem- bling. (5) Leakage shock hazard testing After reassembling the product, always perform an isola- tion chec

27、k on the exposed metal parts of the product (an- tenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the product is safe to operate without danger of electrical shock.Do not use a line isolation transformer during this check. Plug the AC line cord dir

28、ectly into the AC outlet. Using a Leakage Current Tester, measure the leakage current from each exposed metal parts of the cabinet, particular- ly any exposed metal part having a return path to the chassis, to a known good earth ground. Any leakage cur- rent must not exceed 0.5mA AC (r.m.s.). Altern

29、ate check method Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 per volt or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by a 0.15F AC-type capacitor between an ex- posed metal part and a known good earth ground. Measure the

30、AC voltage across the resistor with the AC voltmeter. Move the resistor connection to each exposed metal part, particularly any exposed metal part having a return path to the chassis, and measure the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement.

31、Voltage measured any must not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.). 1.2Warning (1) This equipment has been designed and manufactured to meet international safety standards. (2) It is the legal responsibility of the repairer to ensure that these safety standards are maint

32、ained. (3) Repairs must be made in accordance with the relevant safety standards. (4) It is essential that safety critical components are replaced by approved parts. (5) If mains voltage selector is provided, check setting for local voltage. 1.3Caution Burrs formed during molding may be left over on

33、 some parts of the chassis. Therefore, pay attention to such burrs in the case of pre- forming repair of this system. 1.4Critical parts for safety In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the parts that are printed over with black suc

34、h as the resistor ( ), diode ( ) and ICP ( ) or identified by the mark nearby are critical for safety. When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer. (This regulation dose not Except the J and C version) Good earth ground Place this probe

35、on each exposed metal part.

Avoid direct

36、 exposure to beam. 3.CAUTION : There are no serviceable parts inside the Laser Unit. Do not disassemble the Laser Unit. Replace the complete Laser Unit if it malfunctions. 4.CAUTION : The CD,MD and DVD player uses invisible laser radiation and is equipped with safety switches which prevent emission

37、of radiation when the drawer is open and the safety interlocks have failed or are defeated. It is dangerous to defeat the safety switches. 5.CAUTION : If safety switches malfunction, the laser is able to function. 6.CAUTION : Use of controls, adjustments or performance of procedures other than those

38、 specified here in may result in hazardous radiation exposure. ! Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check.

39、1-5 1.6Hard Disk Drive (HDD) Handling Precautions The HDD is a precision device for use in reading and writing a large amount of data on or from a disk rotating at a high speed. If it is not handled carefully, either abnormal operation may result or it may not be possible to read data. The HDD is se

40、nsitive to the following items and special care is required in safeguarding against them when handling an HDD. Also take care in handling a set incorporating an HDD. (1) Vibrations and impacts (2) Static electricity (3) Rough handling 1.6.1Handling in transport, etc. Be sure to place the HDD in the

41、manufacturers specified pack- age carton before transport. When receiving a package containing an HDD, check that the package carton is not damaged (such as having holes in the carton, crushed corners, etc.). Do not impact the packaging carton when loading or unloading it. It is not permitted to use

42、 the inner package carton only for transporting an HDD. Do not stack package cartons one upon another. 1.6.2Handling an HDD in the stand-alone status When handling an HDD on a hard workbench, place an anti- static mat (rubber sheet) or similar object on the hard surface (to prevent any impacts occur

43、ring between the HDD and bench). Do not stack the HDDs one upon another. Do not knock an HDD with a hard object (such as a screwdriv- er). Do not place an HDD on its side panel without using a support (do not place an HDD in an unstable position). 1.6.3Handling the installation of an HDD Place antis

44、tatic mats or similar sheets on all of the surfaces on which work is conducted or when the HDD is transported. Do not permit the HDD to knock against the sets brackets. When screwing the brackets, be careful not to knock the HDD. When using a power screwdriver, use a low-shock model and arrange the

45、tightening torque properly. When mounting an HDD in a main body, take care not to apply excessive force to the brackets. HDD Do not throw or drop packages. Be sure to package and transport the HDDs correctly. 1-6 (No.YD072) SECTION 2 SPECIFIC SERVICE INSTRUCTIONS Please refer to DR-MH20SE, DR-MH20SE
