  • 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. 3.
