For continued protection, no changes should be madeto the original design unless authorized in writing by themanufacturer. Replacement parts must be identical tothose used in the original circuits. Services should be per-formed by qualified personnel only.(2) Alterations of the design or circuitry of the product shouldnot be made. Any design alterations of the product shouldnot be made. Any design alterations or additions will voidthe manufacturers warranty and will further relieve themanufacture of responsibility for personal injury or propertydamage resulting therefrom.(3) Many electrical and mechanical parts in the products havespecial safety-related characteristics. These characteris-tics are often not evident from visual inspection nor can theprotection afforded by them necessarily be obtained by us-ing replacement components rated for higher voltage, watt-age, etc. Replacement parts which have these specialsafety characteristics are identified in the Parts List of Ser-vice Manual. Electrical components having such featuresare identified by shading on the schematics and by ( ) onthe Parts List in the Service Manual. The use of a substitutereplacement which does not have the same safety charac-teristics as the recommended replacement parts shown inthe Parts List of Service Manual may create shock, fire, orother hazards.(4) The leads in the products are routed and dressed with ties,clamps, tubings, barriers and the like to be separated fromlive parts, high temperature parts, moving parts and/orsharp edges for the prevention of electric shock and firehazard. When service is required, the original lead routingand dress should be observed, and it should be confirmedthat they have been returned to normal, after reassem-bling.(5) Leakage shock hazard testingAfter reassembling the product, always perform an isola-tion check 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 productis safe to operate without danger of electrical shock.Do notuse a line isolation transformer during this check. Plug the AC line cord directly into the AC outlet. Using a“Leakage Current Tester“, measure the leakage currentfrom each exposed metal parts of the cabinet, particular-ly any exposed metal part having a return path to thechassis, to a known good earth ground. Any leakage cur-rent must not exceed 0.5mA AC (r.m.s.). Alternate check methodPlug the AC line cord directly into the AC outlet. Use anAC voltmeter having, 1,000 per volt or more sensitivityin the following manner. Connect a 1,500 10W resistorparalleled by a 0.15µF AC-type capacitor between an ex-posed metal part and a known good earth ground.Measure the AC voltage across the resistor with the ACvoltmeter. Move the resistor connection to each exposed metalpart, particularly any exposed metal part having a returnpath to the chassis, and measure the AC voltage acrossthe resistor. Now, reverse the plug in the AC outlet andrepeat each measurement. Voltage measured any mustnot exceed 0.75 V AC (r.m.s.). This corresponds to 0.5mA AC (r.m.s.). 1.2 Warning(1) This equipment has been designed and manufactured tomeet international safety standards.(2) It is the legal responsibility of the repairer to ensure thatthese safety standards are maintained.(3) Repairs must be made in accordance with the relevantsafety standards.(4) It is essential that safety critical components are replacedby approved parts.(5) If mains voltage selector is provided, check setting for localvoltage.1.3 CautionBurrs formed during molding may be left over on some partsof the chassis. Therefore, pay attention to such burrs in the case of pre-forming repair of this system.1.4 Critical parts for safetyIn regard with component parts appearing on the silk-screenprinted side (parts side) of the PWB diagrams, the parts that areprinted over with black such as the resistor ( ), diode ( )and ICP ( ) or identified by the “ “ mark nearby are criticalfor safety. When replacing them, be sure to use the parts of thesame type and rating as specified by the manufacturer. (This regulation dose not Except the J and C version)Good earth groundPlace this probe on each exposedmetal part.AC VOLTMETER(Having 1000 ohms/volts,or more sensitivity)1500 10W0.15 F AC TYPE1-6 (No.MB706)1.5 Preventing static electricityElectrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laserdiode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.1.5.1 Grounding to prevent damage by static electricityStatic electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products. Be careful to use proper grounding in the area where repairs are being performed. (1) Ground the workbenchGround the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing thetraverse unit (optical pickup) on it.(2) Ground yourselfUse an anti-static wrist strap to release any static electricity built up in your body. (3) Handling the optical pickup In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement opticalpickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.) Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easilydestroy the laser diode. 1MConductive material(conductive sheet) or iron palate(caption)Anti-static wrist strap(No.MB706)1-71.6 Importance administering point on the safetyW109W110 W114ZD121R1226.2B (2.7B)R150R151R152R131R191 R181C133R156R155R154W108W103W107W1 13W1 15W1 19W105IC152IC154378R05278R12(278R05)R15716.FD(+) 15.FD(-) 14.-29VA13.GND 12.5.3VA11.5.3VA10.GND9.GND 6.GND 3.GND 2.3.3V 1.3.3V5.12V 4.12V audio8.P-CON 7.5V loaderW1 17W104W102W106C152L123C126D131R121R144 R145 R146 R143 C143C125D126C124C122C121C123C131D133D122SB360SB360D124D132HER303SB360D121D123(B5A60VI)B5A60VI10A06L127IC15178R12C154C151C153R153J101P10178R33IC153W116W182IC103 D130W183 W111D125R141R142W112L124C132C111C103W101R104C105C106D101BC101R105D102C107 C109IC102T101C104ZD103ZD10110B33BR109FH102C115W118IC101R101C102C110C101R100V101BD101F101T1.6AL 250VFH101L102PW101Graphic symbol mark (This symbol means fast blow type fuse.)FOR CONTINUED PROTECTION AGAINST RISKOF FIRE, REPLACE ONLY WITH SAME TYPEAND RATING OF FUSES ;should be read as follows ;F901 : 3.5A 125V F901 : 3.5A 125VFull Fuse Replacement MarkingFUSE CAUTIONLe symbole graphique (Ce symbole signifiefusible de type a fusion rapide.)POUR UNE PROTECTION CONTINUE CONTREDES RISQUES D'INCENDIE, REMPLACERSEULEMENT PAR UN FUSIBLE DU MEME TYPE ;Marquage Pour Le RemplacementComplet De FusiblePRECAUTIONS SUR LES FUSIBLESdoit etre interprete comme suit ;fast blow type / type a fusion rapide1-8 (No.MB706)1.7 Important for laser products1.CLASS 1 LASER PRODUCT 2.CAUTION : (For U.S.A.)
