11、epair parts.The flexible board is easily damaged and should be handled withcare.NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focusedon the disc reflective surface by the objective lens in the opticalpick-up block. Therefore, when checking the laser diod

12、e emission,observe from more than 30 cm away from the objective lens.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” andcheck that the S curve waveform is output two times.HOW TO OPEN THE DISC TRAY WHEN POWER SWITCHTURNS OFFInsert a tapering driver
