SECTION 1Important Safety Precautions
1.1 Safety Precautions(1) This design of this product contains special hardware and
many circuits and components specially for safety purposes.For continued protection, no changes should be made to theoriginal design unless authorized in writing by the man-ufacturer. Replacement parts must be identical to thoseused 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 special safetycharacteristics are identified in the Parts List of Service Manu-al. Electrical components having such features are iden-tified by shading on the schematics and by ( ) on theParts List in the Service Manual. The use of a substitute re-placement which does not have the same safety character-istics as the recommended replacement parts shown in theParts List of Service Manual may create shock, fire, or oth-er 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 reassembling.
(5) Leakage shock hazard testing)After reassembling the product, always perform an isolationcheck on the exposed metal parts of the product (antennaterminals, knobs, metal cabinet, screw heads, headphonejack, control shafts, etc.) to be sure the product is safe tooperate without danger of electrical shock.Do not use 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 an ACvoltmeter having, 1,000 ohms per volt or more sensitivity inthe following manner. Connect a 1,500 ohm 10W resistorparalleled by a 0.15 F AC-type capacitor between an
exposed 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 metal part,particularly any exposed metal part having a return path tothe chassis, and measure the AC voltage across the resistor.Now, reverse the plug in the AC outlet and repeat eachmeasurement. Voltage measured any must not exceed 0.75V AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.).
1.2 Warning(1) This equipment has been designed and manufactured to
meet 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 the same typeand rating as specified by the manufacturer. (Except the JC version)

1.6 Preventing static electricityElectrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.1.6.1 Grounding to prevent damage by static electricityStatic electricity in the work area can destroy the optical pickup (laser diode) in devices such as CD players. 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 optical
pickup 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.
1.7 Handling the traverse unit (optical pickup)(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. (2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the replace-
ment procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a timewhen attaching it to the connector.
(3) Handle the flexible cable carefully as it may break when subjected to strong force. (4) I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.
1.8 Attention when traverse unit is decomposed*Please refer to "Disassembly method" in the text for the CD pickup unit. Apply solder to the short land sections before the flexible wire is disconnected from the connector CN101 on the CD servo board.
(If the flexible wire is disconnected without applying solder, the CD pickup may be destroyed by static electricity.) In the assembly, be sure to remove solder from the short land sections after connecting the flexible wire.

Precautions for measurement
1. Apply 30pF and 33k to the IF sweeper output
side and 0.082 F and 100k in series to the
sweeper input side.
2. The IF sweeper output level should be made as
low as possible within the adjustable range.
3. Since the IF sweeper is a fixed device, there is no
need to adjust this sweeper.
4. Since a ceramic oscillator is used, there is no need
to perform any MIX adjustment.
5. Since a fixed coil is used, there is no need to adjust
the FM tracking.
6. The input and output earth systems are separated.
In case of simultaneously measuring the voltage in
both of the input and output systems with an
electronic voltmeter for two channels, therefore, the
earth should be connected particularly carefully.
7. In the case of BTL connection amp., the minus
terminal of speaker is not for earthing. Therefore, be
sure not to connect any other earth terminal to this
terminal. This system is of an BTL system.
8. For connecting a dummy resistor when measuring
the output, use the wire with a greater code size.
9. Whenever any mixed tape is used, use the band
pass filter (DV-12).
