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
the
internal
impedance
of the DC circuit tester.
Important safety notice:
Components
identified
by
“\
mark
have
special
characteristics
important
for
safety.
When
replacing
any
of
these
components,
use
only
manufacturer's
specified
parts.
*Caution!
IC and LSI are sensitive to static electricity.
Secondary
trouble
can
be
prevented
by
taking
care
furing
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.
