– 3 – NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, 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 focused on the disc reflective surface by the objective lens in the optical pick- up block. Therefore, when checking the laser diode emission, ob- serve more than 30 cm away from the objective lens.LASER DIODE AND FOCUS SEARCH OPERATION CHECK 1. Close the tray for CD. 2. Press CD u button. 3. Confirm the laser diode emission while observing the objecting lens. When there is no emission, Auto Power Control circuit or Optical Pick-up is broken. Objective lens moves up and down once for the focus search. CAUTION DURING WHEN MOUNTING THE PULLEY FOR THE LOADING MOTOR Make the following adjustment when mounting the loading motor (part number : 1-698-999-11) and motor pulley (part number : 2- 627-174-01) of the CD section. Specification : A = 0.9 to 1.1mm SECTION 1 SERVICE NOTE
