Horizontal time base : 0.5 S/div. (3) Observe the waveform is 1.5V p-p +/-5% and the eye pattern is at its best shape (see F

24、rostatic 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

25、 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 ban

26、d, do not let clothing to get in contact with the pick-up unit. PRECAUTIONS FOR CHECKING BEAM EMISSION The 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 12 inches (30 cm) away from the objective lens

27、 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 properly. (The optical system should be at the l

28、ead-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) movement of the objective lens (2 or 3 tim

29、es) will take place. 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. 1.Grounding band 1M ohm 1M ohm 2.Conductive Sheet or Copper Plate - 11 - PRE

30、CAUTIONS WHEN CHANGING LASER PICK-UP When removing the pick-up assembly, short circuit the PCB tracks on the optical block as show in the drawing in order to protect the pick-up before removal. NOTE: Replacement pick-up assemblies are supplied with the PCB pattern already protected. DO NOT REMOVE TH

31、E SHORT CIRCUITS UNTIL YOU HAVE FINISHED FITTING THE PICK-UP. Caution: Laser diodes are extremely susceptible to damage from static electricity. Even if a static discharge does not ruin the diode, it can shorten its life or cause it to work improperly. When replacing the pick-up, use a conductive ma

32、t, a grounded soldering iron, and so on, to protect the laser diode from static damage.
