(For (GC) area only.)
¢The voltage value and waveforms
are the reference
voltage of this unit measured by DC electronic voltmeter
(high impedance)
and
oscilloscope
on
the basis
of
chassis.
;
Accordingly,
there may
arise
some
error
in voltage
values
and
waveforms
depending
upon
the
internal
impedance of the tester or the measuring unit.
* The parenthesized
are the values of voltage generated
during playing (Test disc 1kHz, L+R, OdB), others are
voltage values in stop mode.

e Important safety notice:
Components
identified
by
A
mark
have _ special
characteristics
important
for
safety.
Furthermore,
special
parts which
have
purposes
of fire-retardant
(resistors),
high-quality
sound
(capacitors),
low-noise
(resistors),
etc.
are
used
as
occation
calls.
When
replacing
any
of components,
be sure
to use
only
manufacturer's specified parts shown in the parts list.
¢The

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.
e Put a conductive mat on the work table.
¢ Do not touch the pins of IC or LSI with fingers directly.
