Notes:
1:
Description
of
the
"FM
IF
Adjustment”
is
not
carried
on
this
Manual.
It
is
because
the
IF
coil
in
the
FM
front
end
section
has
been
best
adjusted
in
the
factory
so
that
its
further
adjustment
is
not
needed
at
the
field.
When
replacing
the
FM
front
end
assembly,
no
adjustment
is
needed
either.
2:
The
parts
in
the
FM
front
end
section
are
prepared
in
a
complete
unit,
so
you
can't
obtain
each
part
individually.
