1 Safety Precautions1.1. General Guidelines
1. IMPORTANT SAFETY NOTICEThere are special components used in this equipment which are important for safety. These parts are marked by in theSchematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical partsshould be replaced with manufacturer’s specified parts to prevent X-RADIATION, shock, fire, or other hazards. Do not modifythe original design without permission of manufacturer.
2. An Isolation Transformer should always be used during the servicing of AC Adaptor whose chassis is not isolated from the ACpower line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personalinjury from electrical shocks. It will also protect AC Adaptor from being damaged by accidental shorting that may occur duringservicing.
3. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated ordamaged by the short circuit.
4. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properlyinstalled.
5. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
1.1.1. Leakage Current Cold Check1. Unplug the AC cord and connect a jumper between the two prongs on the plug.2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on
the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to thechassis, the reading should be between 1MΩ and 5.2MΩ.When the exposed metal does not have a return path to the chassis, the reading must be
1.1.2. Leakage Current Hot Check1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF capacitors, between each exposed metallic part on the set and a
good earth ground such as a water pipe, as shown in Figure 1-1.3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor.4. Check each exposed metallic part, and measure the voltage at each point.5. Reverse the AC plug in the AC outlet and repeat each of the above measurements.6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent)
may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. In case a measurement is outside of thelimits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it isreturned to the customer.
Figure 1-1

1.2. Before Use (For PH only)Be sure to disconnect the mains cord before adjusting the voltage selector as shown in Figure 1-2Use a minus(-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the area in which the unit will beused.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.)
Figure 1-2
1.3. Before Repair and AdjustmentCaution:
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 110~127 V / 220~240 V, 50/60 Hz in FM Tuner at volume minimum mode should be ~ 500 mA (PH).Current consumption at AC 120 V, 60 Hz in FM Tuner at volume minimum mode should be ~ 500 mA (PN).
1.4. 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 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.

2 Warning2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensi-
tive (ES) DevicesSome semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-trostatically Sensitive (ES) Devices.
The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge(ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on yourbody 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 as alumi-num foil, to prevent electrostatic charge buildup 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 removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can
generate electrical charge sufficient 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, aluminum foil or compara-ble 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 bodily 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) suf-ficient to damage an ES device).

2.2. Precaution of Laser Diode
Caution:This product utilizes a laser diode with the unit turned “on”, invisible laser radiation is emitted from the pickup lens.Wavelength: 790 nm (CD)Maximum output radiation power from pickup: 100 µW/VDELaser radiation from the pickup unit is safety level, but be sure the followings: 1. Do not disassemble the pickup unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pickup unit. It was already adjusted.3. Do not look at the focus lens using optical instruments.4. Recommend not to look at pickup lens for a long time.

2.3. Service caution based on Legal restrictions
2.3.1. General description about Lead Free Solder (PbF)The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for thisequipment in considering the globally environmental conservation.
The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin(Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30 degrees C (86°F) more than thatof the normal solder.
Definition of PCB Lead Free Solder being used
Service caution for repair work using Lead Free Solder (PbF)• The lead free solder has to be used when repairing the equipment for which the lead free solder is used.
(Definition: The letter of “PbF” is printed on the PCB using the lead free solder.)• To put lead free solder, it should be well molten and mixed with the original lead free solder.• Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC.• Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the
lead free solder.• Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30 degrees
C (662±86°F).Recommended Lead Free Solder (Service Parts Route.)
• The following 3 types of lead free solder are available through the service parts route.RFKZ03D01K-----------(0.3mm 100g Reel)RFKZ06D01K-----------(0.6mm 100g Reel)RFKZ10D01K-----------(1.0mm 100g Reel)
Note* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
The letter of “PbF” is printed either foil side or components side on the PCB using the lead free solder. (See right figure)

2.4. Handling Precautions for Traverse UnitThe laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must betaken avoid caution to electrostatic breakdown when servicing and handling the laser diode in the traverse unit.
2.4.1. Cautions to Be Taken in Handling the Optical Pickup UnitThe laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body.Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser diode.
1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise structure.2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed
should be short-circuited with a short pin or a clip.3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the flexible cable.4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexi-
ble cable, cut off the antistatic FPC.
Figure 2-2
10
2.5. Grounding for electrostatic breakdown prevention• As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working environ-
ment. Repair in the working environment that is grounded.
2.5.1. Worktable grounding• Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed and ground the sheet.
2.5.2. Human body grounding• Use the anti-static wrist strap to discharge the static electricity form your body Figure 2-3

16 Appendix Information of Schematic Diagram
16.1. Voltage & Waveform ChartNote:
• Indication Voltage Values are in standard values for the unit measured by the DC electronic circuit tester (high-impedance) withthe chassis taken as standard.Therefore, there may exist some errors in voltage values, depending on the internal impedance of the DC circuit tester.
• Circuit voltage and waveform described herein shall be regarded as reference information when probing defect point because itmay differ from actual measuring value due to difference of Measuring instrument and its measuring condition and product itself.
