Refer
to
Pictorial

(fold-out
from
Page

for
the
following
steps.
(A
Position
the
chassis
as
shown.
NOTE:
When
a
wire
end
is
connected
to
a
hole
in
the
circuit
board,
place
the
wire
through
the
hole
in
the
circuit
board,
solder
the
wire
to
the
foil,
and
cut
off
the
excess
length
close
to
the
foil.
In
the
following
steps,
route
all
cables
and
wires
as
shown
in
the
Pictorial.
At
the
1/2"
prepared
end
of
the
10"
shielded
cable,
connect
the
inner
lead
to
hole
S
(S-1)
and
the
shield
lead
to
hole
R
(S-1)
in
the
circuit
board.
(4
-t
the
other
end
of this
cable,
place
a
1"
length
of
sleeving
over
the
shield
lead.
Con-
nect
the
shield
lead
to
lug
2
of
phone
jack
AC
(S-1)
and
the
inner
lead
to
lug
1
of
ter-
minal
strip
AA
(NS).
7)'onnect
a
22
ics2
(red-red-orange)
resistor
from
lug
2
of
phone
jack
AB
(S-1)
to
lug
1
of
terminal
strip
AA
(NS).
)
Connect
a
22
Kn
(red-red-orange)
resistor
from
lug
1
of
phone
jack
AC
(S-1)
to
lug
1
of
terminal
strip
AA
(S-3).
NOTE:
Use
wire
of
the
proper
color
when
wire
is
called
for
in
a
step.
Do
not
use
the
large
red
wire
or
the
large
black
wire
unless
it
is
speci-
fied.
Position
each
wire
as
shown
in
the
Pictor-
ial.
(/)
Prepare
the
following
lengths
of
colored
hookup
wire.
Cut each
wire
to
the
correct
length
and
remove
1/4"
of
insulation
from
both
ends.
These
wires
are
listed
in
the
order
in
which
they
will
be
used:
6-3/4"
black
9-1/4"
yellow
8-3/4"
red
10"
brown
4-3/4"
white
7-1/2"
white
7-3/4" orange
NOTE:
Connections
should
be
made
to
solder
tabs
in
the
following
manner:
Place
the
wire
end
through
the
slot
in
the
chassis.
Then
turn
the
chassis
over,
wrap
the
lead
around
the
tab,
and
solder
the
connection
as
instructed
in
the
step.
