1. SAFETY PRECAUTIONS

1.1. GENERALGUIDELINES

1. Whenservicing. observetheoriginal leaddress. Ifashortcircuit

isfound, replace all parts whichhavebeenoverheatedor

damagedbytheshortcircuit.

2. Afterservicing, see toitthat all theprotectivedevices suchas

insulation barriers, insulation papersshieldsareproperly

installed.

3. Afterservicing, make thefollowing leakagecurrentchecks to

preventthecustomerfrom being exposedtoshock hazards.

1.1.1. LEAKAGE CURRENT COLD CHECK

1. Unplug theACcord and connect ajumperbetweenthetwo

prongson theplug.

2. Measuretheresistance value, withanohmmeter, betweenthe

jumperedACplug and eachexposedmetalliccabinet parton the

equipmentsuchas screwheads, connectors, control shafts, etc.

Whentheexposedmetallicparthas areturn pathtothechassis,

thereading shouldbebetween1M and 5.2 . / Whenthe

exposedmetal does nothaveareturn pathtothechassis, the

reading must be . Fig. 1

1.1.2. LEAKAGE CURRENT HOT CHECK (See Figure1.)

1. Plug theACcord directlyintotheACoutlet. Donotuse an

isolation transformerfor thischeck.

2. Connect a1.5k , 10 watts resistor, inparallel witha0.15 F

capacitors, betweeneachexposedmetallicparton theset and a

good earthground suchas awaterpipe, as showninFigure1.

3. Use anACvoltmeter, with1000 ohms/voltor moresensitivity, to

measurethepotential across theresistor.

4. Check eachexposedmetallicpart, and measurethevoltageat

eachpoint.

5. Reverse theACplug intheACoutlet and repeat eachoftheabove

measurements.

6. Thepotential at anypointshouldnotexceed0.75 volts RMS. A

leakagecurrenttester(Simpson Model 229 or equivalent) maybe

usedtomake thehotchecks, leakagecurrentmust notexceed1/

2milliamp. Incase ameasurementisoutsideofthelimits

specified, thereisapossibilityofashock hazard, and the

equipmentshouldberepairedand recheckedbeforeitisreturned

tothecustomer.

2. Caution for ACMains Lead

3. Before Repairand Adjustment

DisconnectAC power, discharge PowerSupplyCapacitors C707, C717, C718 and C924 through

a 10 , 10 Wresistorto ground. DONOTSHORT-CIRCUITDIRECTLY(with a screwdriver

blade, forinstance), as this maydestroysolidstate devices.

Afterrepairs are completed, restore powergraduallyusing a variac, to avoidovercurrent.

-Currentconsumption at AC230-240 V, 50 HzinNO SIGNALmode

shouldbe~400 mA.

4. Protection Circuitry

The protection circuitrymayhave operatedifeitherof the following conditions are noticed:

-Nosound isheard whenthepoweristurnedon.

-Sound stopsduring aperformance.

The function of this circuitryis to prevent circuitrydamage if, forexample, the positive and

negative speakerconnection wires are

“shorted”, orifspeakersystems with animpedance less thanthe indicatedratedimpedance of

the amplifierare used.

Ifthis occurs, followthe procedure outlines below:

1. Turn off thepower.

2. Determinethecause oftheproblemand correct it.

3. Turn on thepoweronce againafteroneminute.

Note :

Whenthe protection circuitryfunctions, the unitwill not operate unless the poweris firstturned

off and thenon again.

5. Handling the Lead-free Solder

5.1. Aboutleadfree solder(PbF)

Distinction of PbF P.C.B.:

P.C.B.s (manufactured) using leadfree solderwill have a PbF stamp on the P.C.B.

Caution:

-Pbfree solderhas ahighermelting pointthanstandard solder;

Typicallythemelting pointis50 -70°F(30 -40°C) higher. Please

use ahigh temperaturesoldering iron. Incase ofsoldering iron

withtemperaturecontrol, please set itto700 ±20°F(370 ±10°C).

-Pbfree solderwill tend tosplashwhenheatedtoo high (about

1100°F/600°C).

-Whensoldering or unsoldering, please completelyremoveall of

thesolderon thepinsor solderarea, and besuretoheat the

soldering points withthePbfree solderuntil itmelts enough.
