I 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 (DO 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.

* The parenthesized is the voltage for test disc (1 kHz, L+Fi, 0 dB)
in play mode, and the other, for no disc in stop mode.
* AC adaptor is used for power supply.

0 I: : Positive voltage lines.

=> : Audio signal lines.

0 Important safety notice:

Components identified by A mark have special characteristics
important for safety. Furthermore, special parts which have
purposes of fireeretardant (resistors), high-quality sound
(capacitors). low-noise (resistors), etc. are used. When replacing
any of components, be sure to use only manufactures specified
parts shown in the parts list.

Caution!

IC and LS! are sensitive to static electricity.

Secondary trouble can be prevented by taking care during repair.
0 Cover the pans boxes made of plastics with aluminum toll.

0 Ground the soldering iron.

I Put a conductive mat on the work table.

0 Do not touch the pins of IE or LSl with fingers directly.
