1. Before Repair and Adjustment
Disconnect AC power, discharge PowerSupplyCapacitors C301 through a 10 , 5 W resistor
toground. DO NOTSHORT-CIRCUITDIRECTLY (witha screwdriverblade, forinstance), as this
maydestroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, toavoidovercurrent.
Current consumption at AC 220 V, 240 V, 60 Hz inNO SIGNALmode shouldbe ~100 mA
respectively.
2. 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.
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
The laserdiode inthe traverse deck (optical pickup) maybreak downdue topotential difference
causedbystatic electricityof clothes orhumanbody. So, be careful of electrostatic breakdown
during repairof the traverse deck (optical pickup).
-Handling of traverse deck (optical pickup)
1. Donot subject the traverse deck (optical pickup) to static
electricityas itisextremelysensitive to electrical shock.
2. To prevent the breakdownof the laser diode, an antistatic
shorting pinisinserted into the flexibleboard (FFCboard).
3. Take care not to applyexcessive stress to the flexibleboard (FFC
board). When removing or connecting the short pin, finish the job
4

inas short time as possible.
4. Donot turn the variableresistor (laser power adjustment). Ithas
alreadybeen adjusted.
-Grounding for electrostaticbreakdownprevention
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) isplace, 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 Traverse Deck
The traverse deck 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 utilizers aclass 1laser. Invisiblelaser radiation is
emitted from the optical pick up lens.
When the unitisturned on:
1. Donot disassemblethe optical pick up unit, since radiation from
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.

9.1.1. Setting of CD self-diagnosismode /
1. Remove the cassette from the deck.
2. Switch to CD function.
3. Press the CD/TAPE STOPkeyof the mainset for more than 2
seconds. Whilepressing thiskey, press the FF keyon the main
set for another 2seconds to enter into the Self-Diagnosismode.
*Even ifSTOP/ FUNCTIONkeyof the mainset ispressed while
the SelfDiagnosismode ison, function shall not be switched.
Instead, confirmation of error numbers shall begin. /
9.1.2. Setting of cassettemechanism self-diagnosismode /
1. Activate the SelfDiagnosismode with the Deck unloaded.
2. The test mode display([T]at the 1st digitshowsTEST )shall be
made and detection shall be executed to check RECINH SW,
HALFSW are inOFF state.
(the tape counter displayisretained )
3. Load acassette tape (with recording preventive tab present )into
adeck and close the cassette holder.
4. Atthisinstant with the cassette loaded inRECINH SW, HALF SW

shall be checked and confirmed at thisstage bythe software.
Press FF keyto proceed the self-diagnosis. The FF operation shall
stop automaticallyafter 3sec. Ifabnormal operation isdetected,
the tape shall stop automaticallyafter 1sec. During the FF
operation, the Reel Pulse shall be checked bythe software.
5. After the tape stop, the Error codes shall be displayed bytoggling
