NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by

26、the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30cm away from the objective lens. BEFORE REPLACING THE OPTICAL PICK-UP BLOCK Please be sure to check thoroughly the parameters as per the “Optical pick- up Block Checking Proce

27、dure” (Part No. : 9-960-027-11) issued separately before replacing the optical Pick-up block. Note and specifications required to check are given below.
