2. Precaution of Laser Diode
Caution:
Thisproduct utilizes aclass 1laser. Invisiblelaser radiation is
emitted from the optical pick-up lens when the unitisturned on:
1. Donot look directlyinto the pick-up lens.
2. Donot use optical instruments to look at the pick-up lens.
3. Donot adjust the preset variableresister on the optical pick-up.
4. Donot disassemblethe optical pick-up unit.
5. Ifthe optical pick-up isreplaced, use the manufacture’sspecified
replacement pick-up only.
6. Use of control or adjustments or performance of procedures other
than those specified hereinmayresultinhazardous radiation
exposure.

3. 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).
3.1. 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 tipoftheflexible
board. / (Refer to Fig. 3-1. )
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. 3-1. )
Fig. 3-1.
3.2. Caution when replacing traverse deck
The newtraverse deck short-circuits bythe short pin, the foil (B) and short lands toprotect the
laserdiode against electrostatic breakdown. Be sure toreplace tonewone following
procedures.
1. Remove the short pinfrom the FFC, and then connect itto the
connector.
2. Cut the foil (B). (Refer to Fig. 3-1. )(Take care not to make contact

with cutting point each other.)
3. Unsolder the short lands. (Refer to Fig. 3-1. )
3.3. Grounding for electrostaticbreakdownprevention
3.3.1. Human bodygrounding
Use the anti-static wrist straptodischarge the static electricityfromyourbody. (RefertoFig. 3-2.
)
Fig. 3-2.
3.3.2. Worktablegrounding
Put a conductive material (sheet) orsteel sheet on the area where the traverse deck (optical pick
-up) is placed, and ground the sheet. (Referto Fig. 3-3. )
Fig. 3-3.
Caution:
The staticelectricityof your clothes will not be grounded through
the wrist strap.
So take care not to let your clothes touch the traverse deck (optical
pick-up).
