35、So, be careful of electrostatic breakdown during repair of the optical pickup. e Handling of optical pickup Optical pickup 1. Do not give excessive shock to the optical pickup because it is of extremely precise structure. 2. To prevent the breakdown of the laser diode, an anti- static shorting pin i

36、s inserted into the flexible board. (FPC board) When removing or connecting the short pin, finish the job in as short time as possible. 3. Take care not to apply excessive stress to the flexible board. (FPC board) 4. Do not turn the variable resistor (laser power adjust- ment). It has already been a

37、djusted. Variable resistor / - (Do not turn) .Be sure to short this portion (Use the shorting pin or clip.)

So, take care not to let your clothes touch the optical pickup. iron plate or some metals e to conduct electricity. _ B DISASSEMBLY INSTRUCTIONS CAUTION: _ It is very dangerous to look at or touch laser radiation. (Laser radiation is invisible.) o With the unit turned “on”, laser radia
