2. Before Repair and Adjustment
Disconnect AC power, discharge PowerSupplyCapacitors C506, C507, C508, C584 & C311
through a 10 , 5W resistortoground.
DO NOTSHORT-CIRCUITDIRECTLY (witha screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
-Current consumption at AC 230V, 50 HzinNO SIGNALmode
shouldbe ~300 mA. (For E, EG)
-Current consumption at AC 230V -240V, 50 HzinNO SIGNALmode

3. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions are noticed:
-Nosound isheard when the power isturned on.
-Sound 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.
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.
4. Handling the Lead-free Solder
4.1. 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 than standard solder;
Typicallythe melting point is50 -70°F (30 -40°C)higher. Please
use ahigh temperature soldering iron. Incase of 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.
5. Precaution of Laser Diode
Caution :
Thisproduct utilizes alaser diode with the unitturned "ON",
invisiblelaser radiation isemitted from the pick up lens. /
Wavelength :780 nm / Maximum output radiation power from pick
up :100 W/VDE/ Laser radiation from pick up unitissafetylevel,
but be sure the followings:
1. Donot disassemblethe optical pick up unit, since radiation from
5

exposed laser diode isdangerous.
2. Donot adjust the variableresistor on the pick up unit. Itwas
alreadyadjusted.
3. Donot look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for along time.

6. Handling Precautions For Traverse Deck
The laserdiode inthe traverse deck (optical pickup) maybreak downdue topotential difference
causedbystatic electricityof clothes orhumanbody.
So, be careful of electrostatic breakdownduring repairof the traverse deck (optical pickup).
Handling of CD traverse deck (optical pickup)
1. Donot subject the traverse deck (optical pickup) to static
electricityas itisextremelysensitive to electrical shock.
2. The short land between the No.4(LD)and No.5(GND)pins on the
flexibleboard (FFC)isshorted with asolder build-up to prevent
damage to the laser diode (Fig1).
3. Take care not to applyexcessive stress to the flexibleboard (FPC
board).
4. Donot turn the variableresistor (laser power adjustment). Ithas
alreadybeen adjusted.

Grounding forelectrostatic breakdownprevention
1. Human bodygrounding (Fig2)
Use the anti-staticwrist strap to discharge the staticelectricity
from your body.
2. Work tablegrounding (Fig2)
Put aconductive material (sheet) or steel sheet on the area where
the traverse deck (optical pickup) isplaced, and ground the sheet.
Caution :
The staticelectricityof your clothes will not be grounded through
the wrist strap. So, take care not to let your clothes touch the
traverse deck (optical pickup). Fig2

Caution whenReplacing the Optical Pickup :
The traverse has ashort point shorted with solder to protect the
laser diode against electrostatics breakdown. Besure to remove
the solder from the short point before making connections.
