  • Page 7 5. Handling Precautions For Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). - Handling of traverse deck (optical pickup) 1.
  • Page 8 2. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FFC board). 3. Take care not to apply excessive stress to the flexible board (FFC board). When removing or connecting the short pin, finish the job in as short time as possible.
  • Page 9 6. Precaution of Laser Diode Caution: This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. When the unit is turned on: 1. Do not look directly into the pickup lens. 2. Do not use optical instruments to look at the pickup lens.
  • Page 10 3. Do not adjust the preset variable resistor on the pickup lens. 4. Do not disassemble the optical pickup unit. 5. If the optical pickup is replaced, use the manufacturer’s specified replacement pickup only. 6. Use of control or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
