Ñ 3 Ñ SECTION 1 SERVICING NOTE HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF Insert a screwdriver into the aperture of the unit bottom, and move it in the direction of arrow. 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, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the ÒS curve checkÓ in ÒCD section adjustmentÓ and check that the S curve waveform is output two times.
