1. SafetyPrecaution
(This “SafetyPrecaution”is appliedonlyinU.S.A.)
1. Beforeservicing, unplug thepowercord topreventanelectric
shock.
2. Whenreplacing parts, use onlymanufacturer’srecommended
components for safety.
3. Check thecondition ofthepowercord. Replace ifwearor
damageisevident.
4. Afterservicing, besuretorestoretheleaddress, insulation
barriers, insulation papers, shields, etc.
5. Beforereturning theservicedequipmenttothecustomer, besure
tomake thefollowing insulation resistance test topreventthe
customerfrom being exposedtoashock hazard.
-Insulation Resistance Test
1. Unplug thepowercord and shortthetwoprongsoftheplug with
ajumperwire.
2. Turn on thepowerswitch.
3. Measuretheresistance valuewithohmmeterbetweenthejumper

BatteryService Life
UM-1 (D-size)Batteries / Approximately30 hrs of Tape Recording. (EIAJ)/ Approximately16 hrs
of Tape Playback. (EIAJ)/ Approximately11.5 hrs of CD Recording. (EIAJ)/ Approximately10.5
hrs of CD Playback. (EIAJ)
The batteryservice life is measuredaccording to the conditions setforth byEIAJ. (Electronic
Industries Association of Japan). As the batteryservice life varies with the method of operation
and environmental conditions, use these values as reference.
2. Before Repairand Adjustment
DisconnectAC power, discharge PowerSupplyCapacitors C120, C220, C317 through a 10 , 5
Wresistorto ground. DONOTSHORT-CIRCUITDIRECTLY(with a screwdriverblade, for
instance), as this maydestroysolidstate devices.
Afterrepairs are completed, restore powergraduallyusing a variac, to avoidovercurrent.
Current consumption atAC 120 V, 60 HzinNOSIGNALmode shouldbe ~75 mArespectively.
3. Protection Circuitry
The protection circuitrymayhave operatedifeitherof the following conditions are noticed:
-Nosound isheard whenthepoweristurnedon.
-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 Precautions For Traverse Deck
The laserdiode inthe traverse deck (optical pickup) maybreak downdue to potential difference
causedbystatic electricityof clothes orhumanbody. So, be careful of electrostatic breakdown
during repairof the traverse deck (optical pickup).
-Handling oftraverse deck (optical pickup)
1. Donotsubject thetraverse deck (optical pickup)tostatic
electricityas itisextremelysensitivetoelectrical shock.

2. Topreventthebreakdownofthelaserdiode, anantistatic
shorting pinisinsertedintotheflexibleboard (FFCboard).
3. Take carenottoapplyexcessivestress totheflexibleboard (FFC
board). Whenremoving or connecting theshortpin, finishthejob
inas shorttimeas possible.
4. Donotturn thevariableresistor (laserpoweradjustment). Ithas
alreadybeenadjusted.
-Grounding for electrostaticbreakdownprevention
1. Humanbodygrounding
Use theanti-staticwrist straptodischargethestaticelectricity
from your body.
2. Worktablegrounding.
Putaconductivematerial (sheet) or steel sheet on thearea
wherethetraverse deck (optical pickup)isplace, and ground the
sheet.
Caution:
Thestaticelectricityofyour clothes will notbegroundedthrough
thewrist strap. So, take carenottolet your clothes touchthe
traverse deck (optical pickup).
Caution whenreplacing the Traverse Deck
The traverse deck has a shortpoint shortedwith solderto protectthe laserdiode against
electrostatics breakdown. Be sure to remove the solderfrom the shortpoint before making
connections.

6. Precaution ofLaser Diode
Caution:
Thisunitutilizes aclass 1laser. Invisiblelaserradiation isemitted
from theoptical pickup lens. Whentheunitisturnedon:
1. Donotlookdirectlyintothepickup lens.
2. Donotuse optical instruments tolookat thepickup lens.

3. Donotadjust thepreset variableresistor on thepickup lens.
4. Donotdisassembletheoptical pickup unit.
5. Iftheoptical pickup isreplaced, use themanufacturer’sspecified
replacementpickup only.
6. Use ofcontrol or adjustments or performance ofprocedures
otherthanthose specifiedhereinmayresultinhazardous
radiation exposure.
CAUTION!
THIS PRODUCTUTILIZES ALASER.
USE OFCONTROLS ORADJUSTMENTS ORPERFORMANCE OF
PROCEDURES OTHERTHANTHOSE SPECIFIEDHEREINMAY
RESULTINHAZARDOUS RADIATIONEXPOSURE.
