Thisproduct utilizes alaser diode with the unitturned on, invisible
laser radiation isemitted from the pick-up lens.
Wavelength: 780 nm
Maximum output radiation power from pick-up: 100 W/VDE
Laser radiation from the pick-up lens issafetylevel, but be sure the
followings:
1. Donot disassemblethe optical pick-up unit, since radiation from
exposed laser diode isdangerous.
2. Donot adjust the variableresistor on the pick-up unit. Itwas
alreadyadjusted.
3. Donot look at the focus lens using optical instruments.
4. Recommend not to look at pick-up lens for along time.
4. Handling Precautions for Traverse Deck
The laserdiode inthe traverse deck (optical pick-up) maybreak downdue topotential
difference causedbystatic electricityof clothes orhumanbody.
So, be careful of electrostatic breakdownduring repairof the traverse deck (optical pick-up).
4.1. Handling of traverse deck (optical pick-up)
1. Donot subject the optical pick-up to staticelectricityas itis
extremelysensitive to electrical shock.
2. To protect the laser diode against electrostaticbreakdown, be
sure that the short land of the flexibleboard (FFCboard) should
be short-circuitbysolder before pulling out the FFC. Then
inserting ashort pinor similar object into the tipof the flexible
board. / (Refer to Fig. 4-1. )
3. Take care not to applyexcessive stress to the flexibleboard (FFC
board).
4. Donot turn the variableresistor (laser power adjustment). Ithas
alreadybeen adjusted. (Refer to Fig. 4-1. )
