3. Precaution of LaserDiode
Caution:
Thisproduct utilizes alaserdiodewiththeunitturnedon, invisible
laserradiation isemittedfromthepick-up lens.
Wavelength:780 nm
Maximumoutputradiation powerfrompick-up:100 W/VDE
Laserradiation fromthepick-up lensissafetylevel, butbesurethe
followings:
1. Donotdisassembletheoptical pick-up unit, since radiation from
exposedlaserdiodeisdangerous.
2. Donotadjust thevariableresistoron thepick-up unit. Itwas
alreadyadjusted.
3. Donotlookat thefocuslensusing optical instruments.
4. Recommend nottolookat pick-up lensforalong time.
4. Handling Precautions forTraverse Deck
Thelaserdiodeinthetraverse deck (optical pick-up)may break downduetopotential difference
causedbystaticelectricityofclothes or humanbody.
So, becareful ofelectrostaticbreakdownduring repairofthetraverse deck (optical pick-up).
4.1. Handling oftraverse deck (optical pick-up)
1. Donotsubject theoptical pick-up tostaticelectricityas itis
extremelysensitivetoelectrical shock.
2. To protect thelaserdiodeagainst electrostaticbreakdown, be
surethat theshortland oftheflexibleboard(FFCboard)shouldbe
short-circuitbysolderbeforeinserting ashortpinorsimilarobject
intothetipoftheflexibleboard. / (Referto Fig. 4-1. )
3. Take carenottoapplyexcessivestress totheflexibleboard(FFC
board).
4. Donotturnthevariableresistor(laserpoweradjustment). Ithas
alreadybeenadjusted. (Referto Fig. 4-1. )
