2. Precaution of LaserDiode
Caution:
Thisproductutilizes alaserdiodewiththeunitturned“on”, invisiblelaserrediation isemitted
from thepickup lens. / Wave length:780nm / Maximum outputradiation powerfrom pickup:100
W/VDE / Laserradiation from thepickup lensissafetylevel, butbesurethefollowings:
1. Donotdisassembletheoptical pickup unit, since radiation from
exposedlaserdiodeisdangerous.
2. Donotadjust thevariableresistoron thepickup unit. Itwas
alreadyadjusted.
3. Donotlookat thefocuslensusing optical instruments.
4. Recommend nottolookat pickup lensforalong time.

3. Handling Precautions forTraverse Deck
Thelaserdiodeinthetraverse deck (optical pickup)may break downduetopotential difference
causedbystaticelectricityofclothes or humanbody.
So, becareful ofelectrostaticbreakdownduring repairofthetraverse deck (optical pickup).
3.1. Handling thetraverse deck (optical pickup)
1. Thetraverse deck (optical pickup)isanextremelyhigh-precision
construction and must notbesubjectedtoimpact, excessive
vibration, orothertypes ofrough handling.
2. Inordertopreventstaticelectricitydamagetothelaserdiode, use
ashortpinorsimilartool toshorttheoptical pickup’sflexible
circuitboardsaftertheyhavebeendisconnectedfromthemain
circuitboard. (as shownin Fig. 1 )
3. Handletheflexiblecircuitboardswithcare;excessiveforce could
cause themtobebroken.
4. Donotturnthepre-set variableresistor(foradjustmentofthe

1. Humanbodygrounding
Use theanti-staticwrist straptodischargethestaticelectricity
fromyourbody. (as shownin Fig. 3 )
2. Worktablegrounding
Putaconductivematerial (sheet) orsteel sheet on thearea where
thetraverse deck (optical pickup)isplaced, and ground thesheet.
(as shownin Fig. 4 )
Caution
Thestaticelectricityofyourclothes will notbegroundedthrough
thewrist strap.
So, take carenottolet yourclothes touchthetraverse deck (optical
pickup).
