for the
following steps.

Cut
a 1" length of
double-adhesive
tape
from
the
1-foot
length furnished.
Lay this
piece
aside
for use
later.
NOTE: When the
circuit board
is mounted,
lockwashers
must
be
installed
between
the chassis and
the
foil
side
of the
circuit board.
This assures
a
good
ground
between
the circuit
board and
the chassis.
This operation
can be simplified
if
you place
a 1-112"
piece
of
tape over
each screw
head after
the screws
are
placed
in the
holes
from the lettered
side
of
the circuit board.
The
tape
will
hold the screws
in
place
until
lockwashers and
nuts are
installed.
The
tape
furnished
has
adhesive
with a
protective
covering
on each
side.
Remove
the
covering
from one side
only
when
you
tape
the screw
heads.

Cut
six 1'1
12"
lengths
of tape.

Mount
the
circuit
board
on
the
chassis.
(Position
the
board
as shown
in
Plctorial
14.)
Use
6-32
x
318"
hardware.
Tape the
screw
heads
into
place
with
the
1-1
12"
pieces
of
tape.
On
the
lettered
side
of
the
circuit
board,
place
a
#6
solder
lug
under
the screw
head
at
BE. At
BD
place
a
#8
plain
solder
lug on
the
screw
instead
of
a
lockwasher.
Then
raise
the
circuit
board
into
place
and
secure
the
screws
with
lockwashers
and
nuts.
Do
not
place
nuts or
lockwashers
on
the
screws
at
BF
or
BS.

Place
a
#6
solder

Remclve the
tape
from the
screw
heads,
position
each
solder
lug as shown
in the
Pictorials,
and
tighten
each
mounting
screw
securely
so
the
lockwashers
will
bite
into the
circuit
board
foil to
form a
good
connection
to the
chassis.
