(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
S310 : Hold (HOLD) switch in “OFF” position.
S801 : Play/pause (

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.

Important safety notice:
Components identified by
istics important for safety.
Furthermore, special parts which have purposes of fire-re-
tardant (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.

: +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 val-
ues 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 , f or 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.
