CAUTION:
Thisproduct utilizes alaserdiodewiththeunitturned"on",
invisiblelaserradiation isemittedfrom thepickup lens.
Wavelength:780 nm
Maximum outputradiation powerfrom pickup:100 W/VDE
Laserradiation from thepickup lensissafetylevel, butbesurethe
followings:
1. Donotdisassembletheoptical pickup unit, since radiation from
exposedlaserdiodeisdangerous.
2. Donotadjust thevariableresistor on thepickup unit. Itwas
alreadyadjusted.
3. Donotlookat thefocuslensusing optical instruments.
4. Recommend nottolookat pickup lensfor along time.

3. Operating Instructions
4. Handling Precautions for Traverse Deck
The laserdiode inthe traverse deck (optical pickup) maybreak downdue to potential difference
causedbystatic electricity
of clothes orhumanbody.
So, be careful of electrostatic breakdownduring repairof the traverse deck (optical pickup).
4.1. Handling thetraverse deck (optical pickup)
1. Thetraverse deck (optical pickup)isanextremely
high-precision construction and must notbesubjected
toimpact, excessivevibration, or othertypes ofrough
handling.
2. Inordertopreventstaticelectricitydamagetothelaser
diode, use ashortpinor similartool toshorttheoptical
pickup’sflexiblecircuitboardsaftertheyhavebeen
disconnectedfrom themaincircuitboard.
3. Handletheflexiblecircuitboardswithcare;excessive
force couldcause themtobebroken.
4. Donotturn thepre-set variableresistor (for adjustmentof
thelaserpower);ithas beenadjustedat thefactory.

4.2. Grounding for electrostaticbreakdownprevention
1. Humanbodygrounding
Use theanti-staticwrist straptodischargethestatic
electricityfrom your body.
2. Worktablegrounding
Putaconductivematerial (sheet) or steel sheet on the
area wheretheoptical pickup isplaced, and ground
thesheet. (as shownin Fig. 2 )

Caution:
Thestaticelectricityofyour clothes will notbegrounded
through thewrist strap.
So, take carenottolet your clothes touchthetraverse deck
(optical pickup).
5. Operation Checks and ComponentReplacement
Procedures

6. Checking the Operation Problemson the Traverse
Deck (Optical Pickup)
Make sure to followthe procedures belowto check the operation problems of the traverse deck
(optical pickup) before replacing it.
Replace the traverse deck onlyafterthe problemis identified.
