1. Before Repair and Adjustment
Disconnect AC power, discharge PowerSupplyCapacitors C905, C910 through a 10 , 5W
resistortoground.
DO NOTSHORT-CIRCUITDIRECTLY (witha screwdriverblade, forinstance), as this may
destroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
[EG]
-Current consumption at AC 230V, 50 HzinNO SIGNALmode
shouldbe ~160mA.
[EB]
-Current consumption at AC 240V, 50 HzinNO SIGNALmode
shouldbe ~160mA.
2. 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
3

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 Precautions For Traverse Deck (CD/MD)
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.
3. Take care not to applyexcessive stress to the flexibleboard (FPC
5

board).
4. Donot turn the variableresistor (laser power adjustment). Ithas
alreadybeen adjusted.
Handling of MD Unit (optical pickup)
1. Donot subject the MDunit(optical pickup) to staticelectricityas
itisextramelysensitive to electrical shock.
2. The short land between the No.25 (LD-GND)and No. 24 (LD)pins
on the flexibleboard isshorted with asolder builder up to prevent
damage to the laser diode.
3. Take care not to applyexcessive stress to the flexibleboard (FFC).
4. Donot turn the variableresistor (laser power adjustment). Ithas

Grounding forelectrostatic breakdownprevention
1. Human bodygrounding
Use the anti-staticwrist strap to discharge the staticelectricity
from your body.
2. Work tablegrounding
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).
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.
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 mW/VDE/ Laser radiation from pick upunitissafetylevel,
but be sure the followings:
1. Donot disassemblethe optical pick up unit, since radiation from
7

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.
ACHTUNG :

ungefährlich, wenn folgende Punkte beachtet werden:
1. DieLasereinheitnicht zerlegen, da dieStrahlung an der
freigelegten Laserdiode gefährlich ist.
2. Den werkseitigjustierten Einstellregler der Lasereinhitnicht
verstellen.
3. Nicht mitoptischen Instrumenten indieFokussierlinse blicken.
4. Nicht über längere ZeitindieFokussierlinse blicken.
