1. Safety Precautions
1.1. GENERALGUIDELINES
1. When servicing, observe the original lead dress. Ifashort circuit
isfound, replace all parts which have been overheated or
damaged bythe short circuit.
2. After servicing, see to itthat all the protective devices such as
2

insulation barriers, insulation papers shields are properly
installed.
3. After servicing, make the following leakage current checks to
prevent the customer from being exposed to shock hazards.
1.1.1. LEAKAGE CURRENTCOLD CHECK
1. Unplug the AC cord and connect ajumper between the two
prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the
jumpered AC plug and each exposed metalliccabinet part on the
equipment such as screwheads, connectors, control shafts, etc.
When the exposed metallicpart has areturn path to the chassis,
the reading shouldbe between 1M and 5.2 . / When the
exposed metal does not have areturn path to the chassis, the
reading must be . Fig. 1
1.1.2. LEAKAGE CURRENTHOTCHECK (See Figure1.)
1. Plug the AC cord directlyinto the AC outlet. Don not use an
isolation transformer for thischeck.
2. Connect a1.5k , 10 watts resistor, inparallel with a0.15 F
capacitors, between each exposed metallicpart on the set and a
good earth ground such as awater pipe, as showninFigure 1.
3. Use an AC voltmeter, with 1000 ohms/voltor more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallicpart, and measure the voltage at
each point.
5. Reverse the AC plug inthe AC outlet and repeat each of the above
measurements.
6. The potential at anypoint shouldnot exceed 0.75 volts RMS. A
3

leakage current tester (Simpson Model 229 or equivalent) maybe
used to make the hot checks, leakage current must not exceed 1/2
milliamp. Incase ameasurement isoutside of the limits specified,
there isapossibilityof ashock hazard, and the equipment should
be repaired and rechecked before itisreturned to the customer.
2. Handling the Lead-free Solder
2.1. About lead free solder (PbF)
Distinction of PbF P.C.B. :
P.C.B.s (manufactured) using leadfree solderwill have a PbF stampon the P.C.B.
Caution:
-Pb free solder has ahigher melting point that standard solder;
Typicallythe melting point is50 -70°F (30 -40°C)higher. / Please
use ahigh temperature soldering iron. Incase of the soldering
iron with temperature control, please set itto 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 completelyremove all of
the solder on the pins or solder area, and be sure to heat the
soldering points with the Pb free solder until itmelts enough.
3. Before Repair and Adjustment
Disconnect AC power, discharge PowerSupplyCapacitors C546, C547, C548, C549 through a
10 , 1 W resistortoground.
DO NOTSHORT-CIRCUITDIRECTLY (witha screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
Current consumption at AC 230~240V, 50Hz inNO SIGNALmode shouldbe ~250 mA (EB).
Current consumption at AC 230V, 50Hz inNO SIGNALmode shouldbe ~250 mA (EG).
4. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions are noticed:
-Nosound isheard when the power isturned on.
-Stops during aperformance.
The function of this circuitryis toprevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are “shorted”, orif speakersystems withanimpedance less
thanthe indicatedratedimpedance of the amplifierare used.
If this occurs, followthe procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
4

3. Turn on the power once againafter one minute.
Note:
Whenthe protection circuitryfunctions, the unit will not operate unless the poweris first turned
off and thenon again.
5. Connection of the Speaker Cables
-Besure to connect speaker cables before connecting the AC
mains lead.
-The load impedance of anyspeaker used with thisunitmust be 6 .
1. Connect with the included monaural connection cableto the
receiver or amplifier’ssubwoofer output terminal.
2. Connect the AC mains lead to the householdAC outlet.
6. Disassembly Procedure
“ATTENTION SERVICER”
Some chassis components mayhave sharpedges.
Be careful whendisassembling and servicing.
1. Thissection describes procedures for checking the operation of
the major printed circuitboards and replacing the main
5

components.
2. For reassemblyafter operation checks or replacement, reverse
the respective procedures.
Special reassemblyprocedures are described onlywhen required.
3. Select items from the following index when checks or
replacement are required.
6.1. Disassemblyflow chart
The following chart is the procedure fordisassembling the casing and inside parts forinternal
inspection whencarrying out the servicing.
To assemble the unit, reverse the steps showninthe chart below.
