1 Safety Precaution

(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.

1.1 Insulation Resistance Test

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.

2 Before Repair and Adjustment

Disconnect AC power, discharge Power Supply Capacitors C5820 and C5840 through a 10Ω, 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 Circuitry

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:

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 the power is first turned off and then on again.

4 Prevention of Electro 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).

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, whichshould be removed for potential shock reasons 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 aluminium foil, to prevent electrostatic charge build up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to 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 to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges 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 orcomparable conductive 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 other safety precautions.

8. 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).

IMPORTANT SAFETY NOTICE

There are special components used in this equipment which are important for safety.
These parts are marked by in the schematic diagrams, Exploded Views and replacement parts list. It is essential that these
critical parts should be replaced with manufacturer´s specified parts to prevent shock, fire, or other hazards. Do not modify the
original design without permission of manufacturer.

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)

1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock.

2. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FFC board).

3. Take care not to apply excessive stress to the flexible board (FFC board). When removing or connecting the short pin,
finish the job in as short time as possible.

4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted.

5

Grounding for electrostatic breakdown prevention

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

2. Work table grounding
Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, 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 electrostatics breakdown. Be sure to
remove the solder from the short point before making connections.

7 Precaution of Laser 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:

1. Do not look directly into the pick up lens.

2. Do not use optical instruments to look at the pick up lens.

3. Do not adjust the preset variable resistor on the pickup lens.

4. Do not disassemble the optical pick up unit.

5. If the optical pick up is replaced, use the manufacturer’s specified replacement pick up only.

6. 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.
