5. $402
: Power switch in ''on" position.
6. The value in[____]is the reference voltage at stop of turntable,
measured
by DC electronic circuit tester (high-impedance) on
the basis of chassis. (S1.... "'on'')
Therefore, the measured value may include some error depend-
ing on the internal impedance
of DC circuit tester and other
conditions.

8. Important safety Notice:
Components identified by A\ mark have special characteristics
important safety.
When replacing any of these compornents, use only manufacturer's specified parts.
e Reference voltage and waveform at each IC terminal (pin)
This indicated voltage values and waveform are measured by oscilloscope at 33 r.p.m. rotation.
