CLASS 1 LASER PRODUCTNOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the opt

15、ical 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 th

NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concerated so as to be focused on the disc reflective surface bythe objective lens in the optical pick-up block. Therefore, when checking the lase

17、r diode emission, observe from more than 30cm away from the objective lens. 426/11/048GTLDRAWING.AP16811/11640C EXPLODED ASSEMBLY1: ORIGINAL DRAWING 26/11/04.2418191221756151416931020137211112CDRAWING NOTES:-REVISIONS NOTES:-DATEEDITORREVTHIRD ANGLEPROJECTIONBAABCD123E-MAIL s i mon.fr eet haudi opar
