During rep

10、air, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be foc

11、used on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment”

12、and check that the S curve waveform is output two times. HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF Insert a tapering driver into the aperture of the unit bottom, and turn in the direction of arrow. *To close the disc table, turn the driver in the reverse direction.
