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 genera

11、ted 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 L

12、ASER 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

22、J MODE The following operations are performed in the ADJ mode, which is set by connecting the TP1 (ADJ : JW75) terminal to the Ground and turning on the power. During playback, there is no problem even if the GFS is continu- ously LOW. High speed search is prohibited during access. During playback,

23、the gain of focus servo and spindle servo does not decrease. Servo related manual operations and measurement can be performed. (For details of operations, refer to Table of Key Operrations in ADJ Mode.) 4-3. CLV-S MODE The spindle servo for playback sets into the CLV-S mode when the TP2 (AFADJ) term
