23、 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 BodyBe sure to wear a ground band (1M ohm) that is properly to re

24、move any static electricity that may be charged on the body.2. Ground for Work BenchBe 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 doe

25、s not discharge through the body grounding band, do not let clothing to get in contact with the pick-up unit. PRECAUTIONS FOR CHECKING BEAM EMISSIONThe laser beam of this unit is focused on the reflecting surface of the objective lens in the optical system block. Therefore, keep your eyes at least 1

26、2 inches (30 cm) away from the objective lens when the laser diode is ON.(Operation Check Method for Laser Diode and Focus Search Function.)When the POWER switch is turned ON after the chucking plate is removed, observe the objective lens and confirm that the following operations are performed prope

27、rly.(The optical system should be at the lead-in area position when it is checked at this time.)(1) The laser should be at the innermost position after the chucking plate is removed.(2) The diffused light of the laser beam can be seen when the POWER switch is turned ON.(3) Vertical (up and down) mov
