4. Handling Precautions ForTraverse Deck
Thelaserdiodeinthetraverse deck (optical pickup)may break downdueto
potential difference causedbystaticelectricity ofclothes or humanbody. So, be
careful ofelectrostaticbreakdownduring repairofthetraverse deck (optical
pickup).
- Handling oftraverse deck (optical pickup)
1. Donotsubject thetraverse deck (optical pickup)tostaticelectricity as itis
extremelysensitive toelectrical shock.
2. To preventthebreakdownofthelaserdiode, anantistaticshorting pinis
insertedintotheflexibleboard (FFCboard).
3. Take carenottoapplyexcessive stress totheflexibleboard (FFCboard). When
removing or connecting theshortpin, finishthejob inas shorttimeas possible.
4. Donotturn thevariableresistor (laserpoweradjustment). Ithas alreadybeen
adjusted.
- Grounding for electrostaticbreakdownprevention
1. Humanbodygrounding
Use theanti-staticwrist straptodischargethestaticelectricity fromyour body.
2. Worktablegrounding.
Putaconductive material (sheet) or steel sheet on thearea wherethetraverse
deck (optical pickup)isplace, and ground thesheet.
Caution:
Thestaticelectricity ofyour clothes will notbegroundedthrough thewrist strap.
So, take carenottolet your clothes touchthetraverse deck (optical pickup).

against electrostatics breakdown. Besuretoremove thesolderfromtheshortpoint
beforemaking connections.

5. Precaution of LaserDiode
Caution:
Thisunitutilizes aclass 1laser. Invisiblelaserradiation isemittedfromtheoptical
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’sspecifiedreplacement
pickup only.
6. Use ofcontrol or adjustments or performance ofprocedures otherthanthose
specifiedhereinmay resultinhazardousradiation exposure.
CAUTION!

1. SwitchtheSELECTORtoCD and set toTAPE STOP state. (CD PLAY STOP)
2. Press the/CLEAR for thefirst twosecondsand followedbytheFAST
FORWARD keys for anothertwosecondswithoutreleasing the/CLEAR key, it
shall enterintotheSelf-Diagnosticmode.
3. At thestate of[T]display, operate as follows:
-OpentheCD lidand close itrightaway.
-Startrecording TAPE, and STOP itat once.
4. Press /CLEAR key.
