3 SCD-XE600 The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down 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 emis- sion, observe from more than 30 cm away from the objective lens. CLEANING OF OPTICAL PICK-UP LENS In cleaning the lens of optical pick-up, use the air blower. Never use a cotton swab for cleaning the lens of optical pick-up, which otherwise causes a trouble. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT HOW TO OPEN THE TRAY WHEN POWER SWITCH TURNS OFF SECTION 1 SERVICING NOTES A 2 Pull out the tray in the direction of arrow B. 1 Insert a flat-head screwdriver in to a hol e at the bottom, and rotate the cam (66) in the direction of arrow A. cam (66) B
