Indicated
voltage
values
are
the
standard
values
for
the
unit
measured
by
the
DC
electronic
circuit
tester
(high-impedance)
with
the
chassis
taken
as
standard.
Therefore,
there
may
exist
some
errors
in
the
voltage
values,
depending
on

® 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.
When
replacing
any
of
components,
be
sure
to
use
only
manufacturer’s
specified
parts
shown
in
the
parts
list.
® 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 legs of IC or LSI with the fingers directly.
