3 Schematic Diagram Notes
3.1. Schematic Diagram Notes
Notes:
S201 : Laser ON/OFF switch in �OFF� position. (It turns �ON� with disc holder closed.) S202: Rest detector in �OFF� position. (It turns �ON� when optical pickup comes to innermost periphery.) S309 : Play mode selector (MODE) in �NORMAL� position. (RANDOM � NORMAL � RESUME) S310 : Hold (HOLD) switch in �OFF� position. S801 : Play/pause ( / ) switch. S802 : Stop/power off ( / POWER OFF) switch. S803,: Skip/search ( / , / ) switches. S804 [S803 : / , S804 : / ] S805 : Repeat (REPEAT) switch. S806 : Memory/recall (MEMORY/RECALL) switch. S807 : EQ selector (EQ)switch. S808 : Anti-shock (A.SHOCK) switch. S809 : Battery check (BATT CHECK) switch. VR11 : Power supply voltage adjustment. VR701-1, 2 : Headphones volume (VOLUME) control. Important safety notice: Components identified by mark have special characteristics important for safety. Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), lownoise (resistors), etc. are used. When replacing any of components, be sure to use only manufacture�s specified parts shown in the parts list. The supply part number is described alone in the replacement parts. : +B lines. : CD playback signal lines. The voltage value and waveforms are the reference voltage of this measured by DC electronic voltmeter (high impedance) and oscilloscope on the basis of GND terminal (DC IN Jack). Accordingly, there may arise some errors in the voltage values and waveforms depending upon the internal impedance of the tester or measuring unit. Measurement conditions: *AC adaptor is used for power supply. *Set the headphones VR(VR701) to center position(No.5). *Set the hold lock and ANTI-SHOCK switches to ON. *The parenthesized is the voltage for test disc (1 kHz, L+R, 0 dB) in play mode, and the other, for no disc in stop mode.

Caution!!
IC and LSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair. Cover the parts boxes made of plastics with aluminum foil. Ground the soldering iron. Put a conductive mat on the work table. Do not touch the pins of IC or LSI with fingers directly.
