NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic 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 Never look into the laser diode emission from right avove when checking it for adustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (KMS-241C/J1NP). The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform m easures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care.

NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Schematic Diagram: · All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. · All resistors are in and 1/4 W or less unless otherwise specified. · % : indicates tolerance. f · : internal component. · C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. · U : B+ Line. · Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords. · Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. · Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. · Circled numbers refer to waveforms. · Signal path. E : MD PLAY F : FM f : MW/LW L : BUS AUDIO IN
