Ð 3 Ð CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT CHUCK PLATE JIG ON REPAIRING On repairing CD section, playing a disc without the lid (CD), use Chuck Plate Jig. ¥ Code number of Chuck Plate Jig: X-4918-255-1 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 from more than 30 cm away from the objective lens. This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT table is location on the rear exterior. SECTION 1 SERVICING NOTES LASER DIODE AND FOCUS SEARCH OPERATION CHECK 1. Turn OPERATE switch on with to disc inserted and press FUNCTION button to CD position. 2. Open the lid (CD). 3. Turn on S801 as following figure. 4. Press the ( (CD) button. 5. 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 three times for focus search. S801
