  • 1 Before UseBe sure to disconnect the mains cord before adjusting the voltage selector.Use a minus(-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the area in which the unit willbe used. (If the power supply in your area is 117V or 120V, set to the 127V position.)Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage selector for some countries,the correct voltage is already set.)

    2 Before Repair and AdjustmentDisconnect AC power, discharge Power Supply Capacitors C5820 and C5840 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 127 V, 50/60 Hz in NO SIGNAL mode (volume min at CD mode) should be ~500mA.Current consumption at AC 240 V, 50/60 Hz in NO SIGNAL mode (volume min at CD mode) should be ~350mA.

    3 Protection CircuitryThe 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 areshorted, 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) toElectrostatically Sensitive (ES) Devices

    Some semiconductor (solid state) devices can be damaged easily by electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors andsemiconductor chip components. The following techniques should be used to help reduce the incidence of component damagecaused by electro static discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped 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,which should be removed for potential shock reasons prior to applying power to the unit under test.

    2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such asaluminium 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 materialto 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).

    5 Handling the Lead-free Solder5.1. 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 - 70F (30 - 40C) higher. Pleaseuse a high temperature soldering iron. In case of soldering iron with temperature control, please set it to 700 20F (370 10C).

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

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

  • 6 Handling Precautions For Traverse DeckThe laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity ofclothes 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.

    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 thesheet.

    Caution :The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch thetraverse deck (optical pickup).Caution when replacing the Traverse DeckThe traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure toremove the solder from the short point before making connections.

  • 7 Precaution of Laser DiodeCaution :

    This product utilizes a laser diode with the unit turned "ON", invisible laser radiation is emitted from the pick up lens.Wavelength : 780 nmMaximum output radiation power from pick up : 100 W/VDELaser radiation from pick up unit is safety level, but be sure the followings: 1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pick up lens for a long time.

    CAUTION!THIS PRODUCT UTILIZES A LASER.USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULTIN HAZARDOUS RADIATION EXPOSURE.

    The voltage value and waveforms are the reference voltageof this unit measured by DC electronic voltmeter (highimpedance) and oscilloscope on the basis of chassis.Accordingly, there may arise some error in voltage valuesand waveformsdepending upon the internal impedance ofthe tester or the measuring unit.

    Importance safety notice :Components identified by mark have specialcharacteristics important for safety. Furthermore, specialparts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. areused. When replacing any of components, be sure to use

    only manufacturers 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 duringrepair.

    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.
