1 Safety Precaution

1.1 Insulation Resistance Test

(This “Safety Precaution” is applied only in U.S.A.)

Before servicing, unplug the power cord to prevent an electric

shock.

When replacing parts, use only manufacturer’s recommended

components for safety.

Check the condition of the power cord. Replace if wear or

damage is evident.

After servicing, be sure to restore the lead dress, insulation

barriers, insulation papers, shields, etc.

Before returning the serviced equipment to the customer, be

sure to make the following insulation resistance test to prevent the customer from being exposed to a shock hazard.

Unplug the power cord and short the two prongs of the plug

with a jumper wire.

Turn on the power switch.

Measure the resistance value with ohmmeter between the jumper AC plug and each exposed metal cabinet part, such as screwheads, antenna, control shafts, handle brackets, etc.Measure the resistance value with ohmmeter between the jumper AC plugand each exposed metal cabinet part, such as screwheads, antenna, control shafts, handle brackets, etc. Equipment with antenna terminals should read between 2.7M and

3.9M to all exposed parts*. ( Fig.1 ) Equipment without antenna terminals should read approximately infinity to all exposed parts. ( Fig.2 ) *Note : Some exposed parts may be isolated from the chassisby design. These will read infinity.

If the measurement is outside the specified limits, there is a

possibility of a shock hazard. The equipment should be repaired and re-checked before it is returned to the customer.

Fig.1

Fig.2

2 Before Repair and

4 Prevention of Electr o

Adjustment

Disconnect AC power, discharge Power Supply Capacitors C520 and C540 through a 10˜, 5W resistor to ground.

DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.

After repairs are completed, restore power gradually using a variac, to avoid overcurrent.

Current consumption at AC 120V, 60 Hz in NO SIGNAL mode (volume min at CD mode) should be ~600mA.

3 Protection Cir cuitry

The protection circuitry may have operated if either of the following conditions are 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 rated impedance of the amplifier are used.

If this occurs, follow the procedure outlines below:

Turn off the power.

Static Discharge (ESD) to Electrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easily by electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistorsand semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge (ESD).

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, whichshould be removed for potential shock reasons prior to applying power to the unit under test.

After removing an electrical assembly equiped with ES

devices, place the assembly on a conductive surface such as aluminium foil, to prevent electrostatic charge build up or exposure of the assembly.

Use only a grounded-tip soldering iron to solder or unsolder

ES devices.

Use only an anti-static solder remover device. Some solder

removal devices not classified as “anti-static (ESD protected)” can generate electrical charge to damage ES devices.

Determine the cause of the problem and correct it.

Turn on the power once again after one minute.

Note :

When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

Do not use freon-propelled chemicals. These can generate

electrical charges sufficient to damage ES devices.

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 orcomparable conductive material).

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 other safety precautions. Minimize body 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) sufficient todamage an ES device).

5 Handling the Lead-free Solder

5.1 About lead free solder (PbF)

Distinction of PbF P.C.B.:

P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.

Caution:

• Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of soldering iron with temperature control,please set it to 700 ± 20°F (370 ± 10°C).

• Pb free solder will tend to splash when heated too high (about 1100°F/600°C).

• When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the soldering points with the Pb free solder until it melts enough.

6 Handling Precautions For Traverse Deck

The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body.

So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).

• Handling of traverse deck (optical pickup)

Do not subject the traverse deck (optical pickup) to static

electricity as it is extremely sensitive to electrical shock.

The short land between the No.4(LD) and No.5(GND) pins on

the flexible board (FFC) is shorted with a solder build-up to prevent damage to the laser diode.To connect to the PC board, be sure to open by removing the solder build-up, and finishthe workquickly.

Take care not to apply excessive stress to the flexible board

(FFC).

Do not turn the variable resistor (laser power adjustment). It

has already been adjusted.

Fig 6.1

Grounding for electrostatic breakdown prevention

Human body grounding

7 Precaution of Laser

Use the anti-static wrist strap to discharge the static electricity from your body.

Work table grounding

Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed,

and ground the sheet.

Caution :

The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup).

Caution when Replacing the Traverse Deck :

The traverse deck has a short point shorted with solder to protect the laser diode against electroststics breakdown. Be sure to remove the solder from the short point before making connections.

Fig 6.2

Diode

CAUTION:

This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. Wavelength: 780nm. When the unit is turned on:

Do not look directly into the pick up lens. Do not use optical instruments to look at the pick up lens. Do not adjust the preset variable resistor on the pickup lens. Do not disassemble the optical pick up unit. If the optical pick up is replaced, use the manufacturer’s

specified replacement pick up only.

Use of control or adjustments or performance of procedures

other than those specified herein may result in hazardous radiation exposure.

CAUTION!

THIS PRODUCT UTILIZES A LASER.

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUSRADIATION EXPOSURE.

• The voltage value and waveforms are the reference voltage of this unit measured by DC electronic voltmeter (high impedance) and oscilloscope on the basis of chassis. Accordingly, there may arise some error in voltage values and waveformsdependingupon the internal impedance of the tester or the measuring unit.

No mark : Playback << >> : Rec < > : FM (( )) : CD

• Importance safety notice :

Components identified by

mark

have special characteristics important for safety. Furthermore, special parts which have purposes of fireretardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used. Whenreplacingany of components, be sure to use only manufacturer´s specified parts shown in the parts list.

Caution !

IC, LSI and VLSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair.

• Cover the parts boxes made of plastics with aluminium foil.

• Put a conductive mat on the work table.

• Ground the soldering iron.

• Do not touch the pins of IC, LSI or VLSI with fingers

directly.

• The load impedance of any speaker used with this unit must be 6˜.

• Be sure to connect the cable from the right speaker to the right terminal and the cable from the left speaker to the left terminal.

Strip off the outer covering, and twist the center

conductor. Make sure the bare ends of the wires are not unravelled. (If they are, twist them tight again.)

Insert the wire to the rear panel of the unit and close

the lever.

Connection of the Speaker Wiring

Notes :

• To prevent damage to circuitry, never short-circuit positive (+) and negative (-) speaker wires.

• Be sure to connect only positive (red) wires to positive (+) terminals and negative (black) wires to negative (-) terminals.
