This supply
voltage switch is preset by
the
factory at
117
volts.
If you
are
in an area
where the
supply
voltage
is
lower than
110
volts;
loosen
the
holding
screw
and
slide the
switch
to
expose the
105
volt stamping,
refasten
holding
screw.
WARNING
—
Do not
move line voltage switch
from 117
volt
position
unless
you
are certain the supply voltage is
below
110
volts.
Operating the
receiver
under high supply
voltage condi-
tions
with the
switch
in
105
volt position
can
burn out the
tubes
or
materially
shorten
their
life.
It is
possible
that
the
supply voltage can change
throughout
the
day since
more electricity is
usually
being
used
during the
early
evening
hours
when
the
demand is greatest. If the
supply
voltage
switch
has
been set
in
105
volt position for
the
evening
hours of
low
voltage, the
supply
voltage may exceed
110
volts dur-
ing
the
hours
of
small
demand.
If
this
situation
occurs,
the supply
voltage
switch
must then be
moved
to 117
volt
position.
