INSTRUCTION FOR HANDLING OPTICAL SYSTEM BLOCK PICK-UP
Electrostatic breakdown of the laser diode in the optical system block may occur due to a potential difference caused
by electrostatic charge accumulated on clothing, human body, etc. A ground must be provided as follows to prevent
any electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a ground band (1M ohm) that is properly to remove any static electricity that may be charged on the
body.
2. Ground for Work Bench
Be sure to place a conductive sheet (1M ohm) or copper plate with proper grounding on the work bench or other sur-
face on which the pick-up is to be placed.
3. Because the static electricity charge on the clothing does not discharge through the body grounding band, do not
let clothing to get in contact with the pick-up unit.
INCORRECT CORRECT
NOTE: Laser diodes are so susceptible to damage from
static electricity that even if a static discharge does not
ruin the diode, it can shorten its life or cause it to work
improperly.
