The
other
method of
voltage selection
is
a
little
more
complicated.
It is
done by
changing
the position
of
a
PC
card
inside
the fuse
case.
There
are four voltages
that
can be
selected,
two from
each
side
of
the
PC
card,
and
they
are:
1.
120 or
240
VAC,
and
2.
100 or 230
(referred to as
"220"
on
the voltage
select
PCB) VAC.
The
diagram below shows
the location
of
the voltage select
PCB.
